Alaska wolves poisoned by mercury after switching to sea otter diet
Some coastal wolves in Alaska, U.S., have toxic levels of mercury in their bodies after shifting from a terrestrial diet of deer and moose to a marine diet heavy with sea otters, new research finds. Mercury is a naturally occurring heavy metal found in the Earth’s crust. However, human activities like burning coal and fossil […]
No respite for Indonesia’s Raja Ampat as nickel companies sue to revive mines
- Three companies are suing the Indonesian government to be allowed to mine for nickel in the Raja Ampat archipelago, a marine biodiversity hotspot, Greenpeace has revealed.
- The finding comes after the government’s recent revocation of four other mining permits in the area, following a public outcry over environmental damage and potential zoning violations.
- At the same time, the government is also encouraging the development of a nickel processing plant nearby, raising concerns this could fuel pressure to reopen canceled mines to supply the smelter.
- Greenpeace has called for a total mining ban across Raja Ampat and for an end to the smelter project to ensure the conservation of the archipelago’s unique ecosystems and biodiversity.
Paris goal of 1.5°C warming is still too hot for polar ice sheets, study warns
At the landmark Paris climate agreement, nearly every country in the world pledged to a goal to limit warming to well below 2° Celsius (3.6° Fahrenheit) above preindustrial levels by 2100, and work toward a more ambitious goal to limit warming to 1.5°C (2.7°F). The hope is that such a limit will help Earth avoid […]
Pacific island nations launch plan for world’s first Indigenous-led ocean reserve
The governments of the Solomon Islands and Vanuatu have announced their commitment to create a massive multinational Melanesian Ocean Reserve. If implemented as envisioned, the reserve would become the world’s first Indigenous-led ocean reserve, covering an area nearly as big as the Amazon Rainforest. Speaking at the U.N. Ocean Conference underway in Nice, France, representatives […]
‘It’s our garden’: PNG villages fight to prevent mine waste dumping in the sea
- Communities in Papua New Guinea filed a lawsuit asking for a review of an environmental permit awarded in 2020 to companies for the Wafi-Golpu copper and gold mine. But a decision from the country’s Supreme Court had been delayed several times, before happening on June 12, even as other officials have signaled the government’s apparent support for the project.
- The villages are located near the outflow of a proposed pipeline that would carry mining waste, or tailings, from the mine and into the Huon Gulf.
- The companies say the method, known as deep-sea tailings placement (DSTP), would release the waste deep in the water column, below the layer of ocean most important for the fish and other sea life on which many of the Huon Gulf’s people rely.
- But community members are concerned this sediment and the potentially toxic chemicals it carries could foul the gulf — risks they say they were not adequately informed of.
French Polynesia creates world’s largest marine protected area
French Polynesia has announced the creation of the world’s largest marine protected area. Speaking on the first day of the United Nations Ocean Conference in France, French Polynesian President Moetai Brotherson said the MPA will cover the territory’s entire exclusive economic zone (EEZ), or 4.8 million square kilometers (roughly 1.9 million square miles). “We have […]
Coral reefs and seagrass get new protections off Tanzania’s Pemba Island
Tanzania will establish two new marine protected areas off the eastern coast of Pemba Island in the semiautonomous region of Zanzibar, the fisheries minister for Zanzibar announced at the United Nations Ocean Conference in Nice, France, on June 10. Zanzibar’s minister for blue economy and fisheries, Shaaban Ali Othman, said at the conference that the […]
Record-breaking heat wave due to climate change hits Iceland & Greenland: Scientists
In May, both Iceland and Greenland experienced record-breaking heat. A new rapid analysis has found that the heat wave in both regions was made worse and more likely in today’s warmer climate. The analysis was conducted by World Weather Attribution (WWA), a global network of researchers that evaluates the role of climate change in extreme […]
Global ocean acidification has passed safe planetary boundary threshold: Study
A new assessment finds that the world’s oceans crossed the safe threshold for acidification in 2020, breaching a key planetary boundary and posing serious threats to marine life. Ocean acidification is caused when excess atmospheric carbon dioxide, resulting from human activities like burning fossil fuels, dissolves in seawater, forming carbonic acid that increases the water’s […]
‘Madness’: World leaders call for deep-sea mining moratorium at UN ocean summit
- World leaders have renewed calls for a global moratorium on deep-sea mining at the 2025 U.N. Ocean Conference (UNOC) in Nice, France, as the U.S. moves to mine the deep sea in international waters under its own controversial authority.
- Four additional countries have joined the coalition of nations calling for a moratorium, precautionary pause, or ban on deep-sea mining, bringing the total number to 37.
- The U.S., which did not have an official delegation at UNOC, is pushing forward with its plans to mine in international waters — a decision that has drawn criticism from the international community.
Death of tagged white shark on bather protection gear in South Africa sparks debate
The recent killing of a juvenile great white shark on a drum line — a shark control method consisting of baited hooks attached to floating drums — off the east coast of South Africa has sparked a debate over the measures employed to protect swimmers at the expense of the threatened species. The 2.2-meter (7.2-foot) […]
New study dismisses Amazon River runoff as primary cause of sargassum blooms
- Brazil’s northern beaches recently suffered from arrivals of sargassum blooms, a phenomenon affecting Caribbean nations that most scientists so far have associated with nutrients coming from the Amazon River plume into the Atlantic Ocean.
- A recent study suggests that ocean changes are the primary nutrient source for sargassum blooms since 2011, challenging previous hypotheses.
- Sargassum is causing considerable health and economic concerns as large amounts of this brown macroalgae arrive and accumulate in coastal ecosystems of western Africa and the greater Caribbean Sea every year.
- Brazilian authorities are learning from Caribbean countries how to manage sargassum blooms best, and experts think they should keep monitoring possible ocean current changes.
Stars & lighthouses: Marine conservation that blends Pacific Islander wisdom and Western knowledge (commentary)
- The U.N. Ocean Conference this week is tackling a range of issues, such as how to conserve and sustainably use the oceans and marine resources: a new op-ed argues that the strength of Indigenous islander conservation practices lies in their flexibility and adaptability, while Western conservation efforts bring clear, formal, and intentional goals — and that blending the two can return inspiring results.
- “Conservation is not just about the number of lighthouses we build — about visible policies and formal designations — but we must also name and recognize the stars that have guided us all along; the quiet, steadfast traditions that have protected our oceans for thousands of years,” the author writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Indonesian women sustain seaweed traditions in a changing climate
- The women of Indonesia’s Nusa Penida and Nusa Lembongan islands have harvested seaweed for generations.
- Climate change and tourism development now threaten seaweed cultivators’ centuries-old practices.
- In the face of these changes, seaweed cultivators are working with tourism operators and coral-conservation groups to preserve, and adapt, their traditional practices.
Penguin poop helps form clouds over Antarctica, potentially cooling it
In Antarctica, penguin poop, or guano, can cover the ground for miles, especially around penguin colonies with thousands of individuals. In fact, large, brown guano stains on Antarctica’s white ice have even helped scientists discover new penguin colonies from space. A recent study now finds that the massive amounts of guano play a critical role: […]
When our oceans can’t breathe, a sea change is needed (commentary)
- “Even if we can’t see it, the ocean is telling us it can’t breathe. It’s time to listen and to act,” a new op-ed argues as global leaders and changemakers gather for the U.N. Oceans Conference this week.
- When oxygen levels in parts of the ocean drop dangerously low due to land-based pollution, hypoxic “dead zones” where marine life can no longer thrive are the result, driving ecosystem and fisheries collapses.
- These zones have grown by an area the size of the European Union over the past 50 years, but the Global Environment Facility’s Clean and Healthy Ocean Integrated Program is aimed at tackling this overlooked yet expanding threat.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
One-two punch for mangroves as seas rise and cyclones intensify
- More than half of mangroves worldwide may face high or severe risk by 2100 due to increased tropical cyclones and sea level rise, with experts predicting Southeast Asia to be hardest hit under all emissions scenarios.
- A new risk index combines multiple climate stressors — cyclones and sea level rise — with ecosystem service value, providing a novel, globally scalable tool for risk assessment and conservation planning.
- Mangrove loss has major human and economic costs, jeopardizing flood protection worth $65 billion annually and threatening 775 million people dependent on coastal ecosystems.
- Urgent, dynamic conservation and emissions cuts are essential; restoring degraded areas, enabling inland migration, and reducing emissions could significantly reduce risk and buy adaptation time.
Bumble Bee asks court to dismiss lawsuit alleging forced labor in tuna supply chain
- In March, four Indonesian men filed a landmark lawsuit in the U.S. against canned tuna giant Bumble Bee Foods, accusing the company of profiting from abuse and exploitation aboard Chinese-owned vessels supplying its tuna.
- The plaintiffs described brutal conditions while working on vessels that allegedly supplied albacore tuna directly to Bumble Bee, including physical violence, inadequate food, lack of medical care and withheld wages.
- Despite claims of traceability and sustainability, Bumble Bee and its parent company, Taiwan-based FCF, have been linked to a network of vessels implicated in labor abuses. Critics argue the company failed to act on repeated warnings from rights groups and resisted regulatory changes.
- On June 2, Bumble Bee filed papers requesting the federal court handling the case dismiss it on legal grounds. The next step will be for a judge to decide whether to dismiss it or let it proceed.
Climate change and shrinking Arctic sea ice threaten bowhead whales
Bowhead whales are endemic to the icy waters of the Arctic and prefer living in shallow waters near sea ice, filtering krill and tiny crustaceans called copepods for food. However, the Arctic is warming faster than any other region on Earth, and a recent study estimates that if this continues, then by 2100 the whales […]
World Oceans Day: Scientists find new clues about frontiers of ocean life
In 2008, the United Nations recognized June 8 as World Oceans Day to spotlight the rising vulnerabilities facing the oceans that cover more than 70% of Earth’s surface. Seventeen years later, average ocean temperatures have never been higher. Heat stress has hit 84% of the world’s coral reefs. In places as far as Antarctica, whales […]
Researchers race to understand disease killing Caribbean corals at unprecedented rates
- Stony coral tissue loss disease (SCTLD) is a novel coral disease that first emerged in Florida in 2014, and has now spread to 33 countries and territories in the Caribbean, including along the Mesoamerican Reef.
- SCTLD affects an unprecedented number of species (more than 30 species of reef-building corals), spreads quickly, and has a very high mortality rate.
- Researchers are still trying to figure out exactly what causes the disease.
- Researchers are also trying to understand how the coral microbiome is involved in or responds to SCTLD infection, and developing probiotics that they hope will offer an alternative treatment to antibiotics, with fieldwork in Belize, Colombia and elsewhere.
New method can detect nearly every coral genus in Japan from water samples
- Environmental DNA (eDNA) coral research involves analyzing water samples to identify corals based on the DNA that they secrete into the water, largely via their mucus.
- eDNA research on corals can help scientists understand the changes wrought by global warming and marine pollution by providing coral identification data faster and in some cases more accurately than visual surveys by scientists.
- A team of marine scientists based in Japan, an archipelagic nation with a high level of coral biodiversity, has used an eDNA method to develop a system that can detect nearly all of the country’s 85 reef-building coral genera; no other research group in the world has achieved the same level of detection accuracy and coverage for corals using eDNA.
- They released their findings in a study published on May 22.
Hundreds die after flash floods tear through Nigerian market town
At least 200 people have been confirmed dead and 500 more remain missing after flash floods devastated a Nigerian market town, media reported. Torrential rain started early on May 29, and within just a few hours caused intense flooding in the town of Mokwa, Niger state, a major trading hub for northern farmers selling beans, […]
Signs of hope as elephant seals rebound from avian flu in remote Chilean fjord
- An outbreak of avian flu in 2023 hammered a colony of southern elephant seals in Chile’s Tierra del Fuego region, leading to a 50% decline in its population.
- But over the 2024-2025 breeding season, the colony’s population recovered, with 33 pups being born.
- An alliance between the Chilean branch of the Wildlife Conservation Society and the regional environmental department has been monitoring this particular colony for years, braving the remoteness and extreme weather at the southern tip of the Americas.
- Experts posit that the site, Jackson Bay, may serve as a natural refuge from the avian flu because it’s geographically isolated as a fjord.
Samoa’s new marine spatial plan protects 30% of the country’s ocean
- The Samoan government announced June 3 that it has enacted a law establishing a marine spatial plan to sustainably manage 100% of its ocean by 2030.
- The country has also created nine new marine protected areas that cover 30% of its ocean.
- Fishing is prohibited in the new protected areas, which include a migration route for humpback whales.
- The plan became law on May 1.
Cargo ship carrying ‘hazardous material’ capsizes off India coast
On the morning of May 25, a Liberian-flagged cargo ship, MSC ELSA 3, carrying roughly 640 declared containers, sank off the coast of Kerala state in southern India. Indian authorities rescued all 24 crew on board, but most of the containers remain untraced and their contents unknown, raising environmental concerns, reports contributor Navya PK for […]
Marine artificial upwelling, problematic climate solution slow to advance
- Artificial upwelling is a form of geoengineering that aims to use pipes and pumps to channel cool, nutrient-rich water from the deep ocean to the surface. In doing so, it could fertilize surface waters, prompting the growth of plankton, which can then absorb and store large amounts of atmospheric carbon.
- Long considered a potential marine carbon dioxide removal (CDR) method, artificial upwelling has more recently been coupled with seaweed farming to potentially soak up even more atmospheric CO2.
- But technological challenges have plagued open-water upwelling experiments, while environmentalists worry that large-scale use could ultimately prove ineffective and ecologically harmful.
- Experts state that though upwelling could prove a viable solution to improve fisheries and protect coral reefs from marine heat waves, more research is needed. Considering the rapid current pace of climate change, it’s debatable as to whether implementation at scale could come in time to stave off dangerous warming.
From local planting to national plan, Belize bets on mangrove recovery
- Mangroves in Belize protect coastlines, are nursery grounds for fish, and store vast amounts of carbon.
- In 2021, the government of Belize committed to restoring 4,000 hectares (nearly 10,000 acres) of mangroves, and protecting an additional 12,000 hectares (nearly 30,000 acres) within a decade, as part of its emissions reduction target under the Paris climate agreement.
- To support this restoration target, WWF Mesoamerica is developing a national mangrove restoration action plan.
- Restoration initiatives are already underway in areas like Gales Point, Placencia Caye and elsewhere.
US pioneers restoration of deep water corals damaged by country’s worst oil spill
- Scientists are conducting a pioneering large-scale deep-sea coral restoration in the Gulf of Mexico following the 2010 Deepwater Horizon oil spill, which damaged 1,994 square kilometers (770 square miles) of seafloor habitat.
- Underwater robots and Navy divers using specialized gear to work at depths up to 100 meters (328 feet) plant coral fragments on the ocean floor, while labs in Texas, South Carolina and Florida grow corals in tanks for future transplantation.
- The novel eight-year, multi-million-dollar project has achieved milestones including high deepwater coral survival rates at sea and the first successful spawning of deep-sea corals in captivity, which produced more than 1,000 baby corals.
- The restoration faces ongoing threats from climate change, commercial fishing, agricultural runoff and potential future oil spills, with nearly 1,000 spills occurring in U.S. waters in 2021 and 2022 alone.
Only a tiny % of the deep seafloor has ever been visually observed: Study
- Just 0.001% of the deep seafloor has ever been captured by photo or video images, a new study finds.
- That which has been captured is “biased” and potentially unrepresentative: 65% of observations have been in the waters of the United States, Japan or New Zealand, according to the study.
- Experts told Mongabay that policymakers at a wide range of international institutions should bear the study’s findings in mind, including those governing high seas fisheries, deep-sea mining, and the use of marine carbon dioxide sequestration systems.
UK signs deal handing over Chagos to Mauritius, but tensions remain
The U.K. recognized the Indian Ocean island of Mauritius’ claim to the Chagos Archipelago in an agreement signed May 22. While Mauritian Prime Minister Navin Ramgoolam praised the deal, it elicited mixed reactions from many Chagossians, the islands’ original inhabitants. Starting in 1968, they were displaced from the chain of islands by British colonial rulers to […]
New map highlights complex web of marine migrations
- Scientists have launched a new database on marine migratory patterns to address gaps in the knowledge of policymakers and conservationists.
- The Migratory Connectivity in the Ocean (MiCO) database pulled data from 1,300 existing studies in the scientific literature to describe the migratory patterns of 109 mammal, bird and fish species.
- The database highlights the interconnected nature of marine migrations, and underscores the need for cross-border collaboration in conservation efforts.
Tuna fishing devices drift through a third of oceans, harming corals, coasts: Study
- Drifting fish aggregating devices (dFADs) are floating rafts with underwater netting used by fishing vessels to attract tuna.
- A recent study estimated that between 2007 and 2021, 1.41 million dFADs drifted through 37% of the world’s oceans, stranding in 104 maritime jurisdictions and often polluting sensitive marine habitats.
- Strandings were most frequent in the Indian and Pacific oceans, with the Seychelles, Somalia and French Polynesia accounting for 43% of cases; ecosystem damage and cleanup costs fall on local communities.
‘Satellites for Biodiversity’ upgrades with new projects and launches insight hub
The Airbus Foundation and the Connected Conservation Foundation (CCF) recently announced the winners of their “Satellites for Biodiversity” grant, which now uses higher-resolution satellite imagery to aid conservation efforts. They also launched an Ecosystem Insight Hub, which comprehensively documents the processes and findings of their grantees. The latest batch of six “Satellites for Biodiversity” awardees […]
Coral reef research dominated by rich countries, plagued with inequities: Study
- A new study finds that coral reef researchers come mainly from institutions in high-income countries, and that the contributions of researchers from tropical, lower-income nations aren’t adequately recognized.
- “Parachute” research that leaves out local input is common, and when more local researchers are included, they report that it’s often done in a tokenistic way, the study finds.
- The lead authors say the same communities that face the most direct impacts from the demise of coral reefs are left out of the scientific study of reefs.
Brazil advances with plan to drill oil at the mouth of the Amazon River
Brazil’s environmental agency, IBAMA, approved a key step that could soon allow Petrobras, the nation’s state oil company, to begin offshore oil drilling near the mouth of the Amazon River. In a May 19 decision, the agency greenlit a concept for an emergency response plan by Petrobras (PBR) to protect marine animals in case of […]
Indigenous Bajo suffer child deaths & toxic sludge amid green energy push
- Nickel mining on Kabaena Island has caused severe environmental degradation, threatening the health, livelihoods and cultural identity of the Indigenous Bajo people and resulting in child deaths due to toxic sludge.
- Investigations by environmental groups revealed dangerous heavy metal contamination, deforestation and violations of environmental laws, linking the mining operations to politically exposed persons and global electric vehicle supply chains.
- Indonesia’s Environment Ministry has acknowledged the crisis, pledged enforcement and is developing restoration plans but has so far avoided criminal charges.
- Local activists and experts call for a moratorium on mining permits and stronger law enforcement, stressing that temporary fixes and economic gains must not come at the cost of human lives and ecological collapse.
The blobby little sea squirt that stowed away across the Pacific to California
- In 2023, scientists found a nonnative species of marine invertebrate in a private marina near Los Angeles, California.
- The arrival of this new member of California’s marine fauna highlights the massive, largely uncontrolled movement of marine species via ships that travel the world.
- Concerned about potential ecological and economic impacts, the state of California has tried to curb the movement of nonnative marine species through regulations of large ships and commercial ports, but the regulations don’t apply to smaller vessels.
- Beginning in 2025, California will have to comply with less-stringent federal biofouling and ballast water regulations.
West Sulawesi erupts in protest over sand mining for Indonesia’s new capital
- Hundreds of protesters, including Indigenous and coastal youth from Karossa, Pasangkayu and Kalukku, rallied on May 5 at the West Sulawesi governor’s office to demand the closure of PT Alam Sumber Rezeki’s sand mining operations, citing environmental harm, permit irregularities and lack of community consent.
- Tensions flared after Governor Suhardi Duka dismissed anti-mining resistance as “thuggery,” triggering public outrage and a clash with security forces during the protest, where demonstrators were met with water cannons and no official response.
- The mining, tied to supplying materials for Indonesia’s new capital, Nusantara, has fueled a wider grassroots resistance across West Sulawesi, with activists condemning the criminalization of local opposition and calling for meaningful community involvement in environmental decision-making.
Scientists underestimate frequency of South Atlantic heating events: Study
A new study finds that scientists have likely underestimated heat stress on coral reefs in the South Atlantic Ocean, further raising concerns for coral bleaching amid climate change. The study notes that while the Caribbean and Indo-Pacific have well-established long-term ocean temperature and coral monitoring programs, the South Atlantic Ocean has lagged behind, causing gaps […]
New study maps the fishmeal factories that supply the world’s fish farms
- In April, scientists published the first-ever open-source map of fishmeal and fish oil factories around the world.
- The scientists found 506 factories across some 60 countries, and in most cases were able to identify the companies that own them.
- Fishmeal and fish oil production is controversial because it can incentivize the overexploitation of ocean ecosystems, depleting marine food webs, and negatively impact coastal communities that rely on fish for nutrition and livelihoods.
- In addition to location data, the scientists collected data on the types of fish many of the factories use and whether the raw material they process is fish byproduct or whole fish, which critics view as more problematic.
Brazil’s offshore wind farms could sacrifice small-scale fishing in Ceará
- In Brazil, the expansion of coastal wind energy has already disrupted traditional communities’ way of life; now, the concern is that these impacts will be repeated at sea, after a bill regulating offshore wind energy was signed into law in January.
- In the state of Ceará, 26 projects overlap with small fishing zones used by hundreds of traditional communities, including maroon, Indigenous, fisher and extractivist groups that have had a direct relationship with the sea for generations.
- The northeast region seeks to expand offshore wind energy, as it is vital to the production of green hydrogen aimed for European markets.
Antibiotic pollution widespread in world’s rivers, study finds
Nearly a third of all antibiotics that people consume end up in the world’s rivers, a new study finds. This could potentially harm aquatic life and impact human health by promoting drug resistance, researchers say. Antibiotics, critical for treating various bacterial infections, are widely consumed by people, livestock and aquaculture fish, but the drugs are […]
How a road engineer became an ocean activist & won the world’s top environmental prize
Carlos Mallo Molina has been awarded the 2025 Goldman Environmental Prize for protecting the marine biodiversity of Tenerife, the most populated of the Canary Islands. On this episode of Mongabay’s podcast, Molina explains what led him to quit his job as a civil engineer on a road project impacting the Teno-Rasca marine protected area (MPA) […]
The Great Whale Conveyor Belt (cartoon)
While migrating between their feeding and mating grounds, baleen whales transport massive amounts of nutrients across latitudes. This phenomenon is termed “The Great Whale Conveyor Belt”, prompting scientists to argue that whale conservation can help improve the resilience of global marine ecosystems.
Cruise ships and intensified tourism in Mexico threaten whale shark habitat
- In Baja California Sur, Mexico, a private tourism company, Aquamayan Adventures, and the port administration have reached an agreement that allows mega cruise ships to enter Bahía de La Paz. Environmental organizations are urging the government to cancel the agreement.
- The agreement allows at least 150,000 annual visitors, a figure four times that of cruise passengers received in 2023 and equivalent to 60% of the resident population of the city of La Paz, the state’s capital.
- In addition, the company intends to build a large tourism and commercial complex that could have serious environmental, social and economic impacts on the city and surrounding area, according to organizations concerned about the project.
- Bahía de La Paz is a critical location for marine species like the whale shark, which was affected by the presence of a high number of mega cruise ships in 2020, and which could now be the victim of collisions with vessels arriving to port.
Angling for answers, this saltwater fishing group boosts research for better conservation
- Though anglers aren’t generally thought of as environmentalists, many people who fish are conservation minded, whether because it’s an outdoor pursuit, or because they wish to ensure future harvests.
- Whatever their reasons, there aren’t many groups that help anglers advocate for sustainable fishing regulations based on solid science, nor ones that also work to generate new data that helps them argue for better conservation.
- “Until we came along, there was no voice for those saltwater anglers who cared about conservation, but didn’t have enough time to put into it to really understand it,” says American Saltwater Guides Association vice president Tony Friedrich.
- His team not only helps its members articulate the need for conservation and regulation, they actively participate in developing data that helps managers set better limits, through projects like their GotOne App.
Down on the ranch with Mafia Island’s free-range sea cucumbers
- Sea cucumbers are prized as a delicacy in East Asia and used in some forms of traditional medicine.
- Because of the high demand for them, their populations have fallen off a cliff in Tanzania and elsewhere, landing many species on the IUCN’s red list.
- After banning exports from mainland Tanzania in 2003, the government has recently begun to encourage sea cucumber farming and ranching.
European body proposes mass killing of cormorants to protect fish stocks
A regional fishery body is seeking to reduce cormorant numbers across Europe through “coordinated” culling, citing the aquatic birds’ reported impacts on fisheries and aquaculture. The European Inland Fisheries and Aquaculture Advisory Commission (EIFAAC), a body under the Food and Agriculture Organization (FAO) of the U.N., published its draft plan on April 25. The proposal […]
There’s something fishy about ‘blue economy’ proposals for sustainable marine management (commentary)
- Proposals for developing a “blue economy” emerged in the 2010s as a vision for sustainable ocean development, as communities across the world grappled with challenges of declining ocean health, economic crises and stalling development outcomes.
- Central to their appeal is a promise to transform human interactions with the ocean, promoting a shift toward ecological health, improved livelihoods and job creation, but too often these proposals have been driven by large nations and interests, rather than small coastal nations whose prosperity is most heavily linked with marine ecosystems.
- The author of this commentary warns that this sustainable ocean vision may be operating as a tool for pacifying demands for sustainable and equitable ocean relations, rather than as one that advances them.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Our responsibility for cetacean conservation grows with proof of their intelligence (commentary)
- In the search for other intelligent life in our galaxy, we must look to the oceans before we turn to the stars, states the writer of a new commentary.
- In recent years, cetacean researchers have shown that whales, dolphins and porpoises live socially complex lives that require elaborate communication systems, and possibly even language.
- “If people can understand what they have in common with an animal that is seemingly so alien on the surface, it would allow for a greater extension of empathy,” and therefore greater conservation efforts, the writer argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
World’s top seafood firms lobby against ocean conservation measures: Report
- The world’s most influential seafood companies and industry associations mostly lobby against environmental protections, a report by the U.K.-based NGO InfluenceMap found.
- The report assesses the biodiversity-related lobbying efforts of a list of the 30 most influential seafood companies in the world and 12 of the main industry associations they’re members of.
- The vast majority of the companies and industry associations engage in lobbying that’s misaligned with international biodiversity goals agreed to in a 2022 treaty.
- Industry associations told Mongabay that they support science-based policy and that the report is flawed.
Mozambique announces petrochemical city on sensitive Inhambane seascape
In April this year, Mozambican President Daniel Chapo announced the launch of a national petrochemical city project in Mavanza village in Vilankulo district of Inhambane province. The coastline of Inhambane province, or the Inhambane seascape, is a globally important area that conservation groups have previously urged the government of Mozambique to protect for its threatened […]
Warming seas and illegal trawlers threaten West Africa’s fishing future, study warns
A new paper paints a grim picture for the future of fishing communities in the Gulf of Guinea along coastal West Africa. Faced with increasing ocean warming and declining fish stocks, fishing communities in Ghana, Côte d’Ivoire and Nigeria struggle to survive. The paper’s authors advocate for income diversification among fishing communities as a critical […]
Annual ocean conference nets $9.1 billion for initiatives, despite US absence
- The 10th annual Our Ocean Conference took place in Busan, South Korea, April 28-30.
- Delegates announced 277 new commitments totaling around $9.1 billion for initiatives across the conference’s six main target areas: the ocean-climate nexus, marine pollution, MPAs, sustainable fisheries, the blue economy and maritime security.
- Notable commitments at this year’s conference included Panama moving to increase fisheries transparency, $6 billion in funding for blue economy initiatives and more pledges to ratify the high seas treaty.
- This marked the first OOC without delegates or financial pledges from the U.S. government, which initiated the conference in 2014.
A Honduran reef stumps conservationists with its unlikely resilience
- The latest “report card” on Mesoamerica’s coral reefs made clear that 2024’s hottest-ever recorded summer temperatures devastated some of the region’s most iconic reef sites.
- But against all odds, a reef in Tela Bay on Honduras’s Caribbean coast, composed largely of critically endangered elkhorn corals (Acorpora palmata), displays remarkable health.
- Known affectionately as “Cocalito,” this patch of coral is raising urgent questions about what qualities endow coral with heat resilience and whether they can be harnessed to help save other reefs.
Building a future from seaweed in coastal Tanzania
PEMBA ISLAND — Tanzania. The coastal communities on Pemba Island, off the coast of Tanzania, have long depended on the rich marine resources of the Indian Ocean. But in recent years, fish stocks have declined due to overfishing, habitat loss, and the impacts of climate change. Many have had to seek new ways to earn […]
Blue whale decline in Sri Lanka tied to climate and human activity
- A resident population of blue whales has for many years lived in the coastal waters of Sri Lanka, but in recent years sightings of the animals have declined rapidly.
- With multiple pressures on these massive creatures — from ship traffic on one of the world’s busiest shipping lanes, to disturbance from whale tourism, pollution and surface sea temperature rise and climate change — there are several possible factors for the disappearance of the whales.
- Sri Lanka’s leading marine researchers agree that increasing sea temperatures in the North Indian Ocean, warming at the fastest rate of any of the world’s oceans, have likely pushed the whales to new waters.
The Metals Company applied to the U.S. for a deep-sea mining license
- The Metals Company (TMC) has submitted its first application to commercially exploit seabed minerals in international waters, along with applications for two exploration licenses, under the U.S. regulatory authority.
- The contentious move follows a recent executive order from the Trump administration that directed the U.S. government to fast-track deep-sea mining in an effort to secure supplies of critical minerals for the U.S.
- Both TMC and the U.S. have faced international pushback over these plans, with both the U.N.-affiliated International Seabed Authority (ISA) and China criticizing them as potentially violating international law because only the ISA has the authority to permit mining in international waters.
- While the U.S. regulator and TMC say they will manage environmental risks, critics say deep-sea mining could cause significant and potentially irreversible damage to marine ecosystems.
Protecting coastal waters may be the best investment you’ve never heard of, says Kristin Rechberger
- In this interview, Kristin Rechberger—founder of Dynamic Planet and a Mongabay board member—discusses Revive Our Ocean, a new initiative empowering coastal communities to establish marine protected areas (MPAs) that benefit both nature and livelihoods.
- With only 3% of the ocean fully protected and the 2030 “30×30” target looming, Rechberger argues that waiting on governments isn’t enough; community-led efforts are crucial to scaling marine conservation rapidly and equitably.
- Drawing on a decade of experience creating large offshore marine reserves, Rechberger is now focusing on coastal regions where local communities have a direct stake in healthy seas—but often lack the legal authority, tools, or support to act.
- She emphasizes that marine protection is not only ecologically effective but economically smart, citing examples like Spain’s Medes Islands Reserve and Mexico’s booming dive tourism as models for prosperity through conservation.
Under Trump, US retreats from global fisheries and oceans leadership
- The United States has long been an international leader in fisheries and oceans science, with influence at international fora that it has sometimes wielded to support conservation measures and crackdowns on illegal fishing.
- However, U.S. influence at fisheries and oceans fora appear to be waning during the second Trump administration, which could compromise fisheries health and marine conservation, experts say.
- The administration, which took office Jan. 20, has begun to institute a program of budget and staff cuts at U.S. departments and agencies that work on fisheries and oceans governance, while turning away from or undercutting multilateral organizations.
Scientists warn coral restoration can’t keep pace with global reef collapse
- Coral restoration is vastly outpaced by degradation, while intensifying climate stress, prohibitive costs, poor site selection and lack of coordination make large-scale restoration currently unviable, a new study has found.
- The scale-cost mismatch is staggering: Restoring just 1.4% of degraded coral could cost up to US$16.7 trillion, while current global funding is only US$258 million.
- The study found most projects assessed prioritize convenience over ecological value, restoring easily accessed reefs instead of climate-resilient or biologically strategic ones, undermining long-term outcomes.
- Researchers say standardized data and smarter planning are urgently needed to ensure that global coral restoration is scientifically informed and strategically targeted, and not merely symbolic.
‘We belong to one ocean’: Indigenous leaders push for seat at the table of high seas biodiversity treaty
- Members of Indigenous peoples and coastal communities convened at the United Nations Permanent Forum on Indigenous Issues to call for their inclusion in the Agreement on Marine Biodiversity of Areas Beyond National Jurisdiction (BBNJ), also known as the High Seas Treaty.
- These are the first-ever calls by Indigenous and coastal communities as members attending the forum prepare for the entry into force of the BBNJ agreement.
- Their participation could include involvement in governance, environmental management, and best-practice strategies based on traditional ecological knowledge and values.
- The BBNJ agreement will enter into force once at least 60 countries ratify it. So far, 113 countries have signed the agreement, while 19 have ratified the treaty.
Southeast Asia’s fisheries thrive despite decades of overfishing warnings: Study
- Overfishing in Southeast Asia’s coastal waters is a long-standing concern, but recent research suggests a more optimistic outlook, with 43% of marine stocks classified as underfished — 3.6 times higher than the global average.
- The study, covering stocks across the Indian and Pacific Oceans, highlights the region’s relatively abundant fisheries, particularly among pelagic species, 63% of which are underfished.
- Southeast Asia’s fisheries production surged by 7.1 million metric tons from 1993 to 2022, the largest increase globally, with Indonesia, Vietnam and Myanmar as major contributors.
- The research underscores the importance of small-scale artisanal fisheries that use nonselective methods to target multiple species, and co-management frameworks to maintain production and sustainability.
Global offshore oil platforms are among top ocean polluters, report finds
Most new oil and gas projects in 2024 were located offshore, where spills can be hard to detect. Researchers at the nonprofit SkyTruth recently published a report identifying the biggest sources of pollution from offshore oil, including oil leaks, transportation emissions and methane flaring, as well as the most polluted locations. Christian Thomas, a geospatial […]
Oil companies have downplayed extent of spills in Gulf of Mexico, investigation finds
- Mongabay Latam and Data Crítica examined and compared official data of oil spills in the Gulf of Mexico, including satellite images by scientists studying oil spills and evidence compiled by fishing communities. Their analysis found that most oil spills are not reported.
- Occasionally, even the spills that are reported are played down. The volume of the Ek’ Balam oil spill in 2023 — the most serious spill in Mexico in recent years — was under-reported by 10 to 200 times, according to calculations performed by scientists using satellite images of the disaster.
- Between January 2018 and July 2024, the government of Mexico initiated 48 sanctioning processes against oil companies, but fines were only imposed in fewer than half of those cases. And only eight of those fines have been paid.
- Fishers are demanding oil companies release actual data and take responsibility and the government take action to protect their environment and livelihood.

Trump moves to begin deep-sea mining despite environmental and legal concerns
U.S. President Donald Trump signed an executive order on April 24 to expedite the process of exploring and mining for valuable minerals found on the deep ocean seafloor, in both U.S. and international waters. It’s a highly controversial move that critics say imperils an important but poorly understood ecosystem and flouts international rules on deep-sea […]
Whales and dolphins at risk as report reveals ecological decline in Gulf of California
- The recent “Assessment of the Ecological Health of the Gulf of California” report shows a decline in several populations of animals throughout the narrow sea flanked by the Mexican mainland and Baja California.
- The report was compiled by the Next Generation Sonoran Desert Researchers (N-Gen) in the U.S. in collaboration with Prescott College’s Kino Bay Center field station in Mexico, and draws on long-term monitoring studies.
- Many of the assessed groups, such as seabirds, whales, giant squid, crabs, starfish and fish, are in decline.
- Basic primary productivity, which nurtures species diversity and abundance in the Gulf of California, remains stable.
‘It has been worth it’: The local women saving Yucatán’s mangroves
- Mangrove forests provide important ecosystem services, from acting as nurseries for fish to buffering coasts from storms.
- Mangroves along the northern coast of the Mexican state of Yucatán have been impacted by deforestation and highway and port development.
- A group of women called Las Chelemeras has for the past 15 years worked to restore the region’s mangrove forests and ecosystem function.
- Their restoration tasks involve opening and maintaining channels so that water can infiltrate and drain with the tides, and planting mangrove tree seedlings.
The wisdom of the elders: Why the oldest animals matter
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In the twilight of their lives, the world’s oldest creatures carry the weight of wisdom, experience, and resilience. Yet, these elders — fish that spawn in abundance, coral that shelters marine life, or elephants that guide their herds […]
Indian trawlers leave Sri Lankan small-scale fishers a ravaged, bereft sea
- Bottom trawlers from India’s southern state of Tamil Nadu have been encroaching Sri Lanka’s northern waters for years, carrying out destructive fishing practices that have caused serious depletion of fish stocks and damaged marine habitats.
- Meanwhile, Sri Lanka’s local small-scale fishers continue to struggle due to reduced catches, destruction of their fishing nets and financial loss while being forced to fish in limited nearshore areas or abandon fishing temporarily to avoid conflict with the trawlers.
- In this political bone of contention, Tamil Nadu has been demanding reclamation of Katchatheevu — an uninhabited island between India and Sri Lanka — to gain unrestricted fishing rights, and the past bilateral promises to phase out bottom trawling have gone unfulfilled.
- Sri Lanka banned bottom trawling in 2017 and now needs to take specific actions to prevent illegal bottom trawling in its northern waters to avoid the risk of fisheries there from collapsing.
Ongoing global coral bleaching event affects 84% of world’s reefs
Coral reefs around the world have been subjected to unprecedented heat stress since early 2023. A new report finds heat-related coral bleaching has damaged corals in more than 80 countries, making it the most extensive bleaching event ever recorded, with no clear end in sight. Between January 2023 and April 2025, heat stress impacted 84% […]
Earth Day: The wonder of iconic satellite images
There’s something about viewing Earth from space — the shift in perspective has for decades moved us emotionally, scientifically, and philosophically. The iconic Earthrise image of our planet rising above the lunar horizon, taken in 1968 by astronauts aboard the Apollo 8 mission, is widely credited with fueling the environmental movement that led to the […]
With deep-sea mining plans in limbo, Norwegian companies fold or dig in
- Norway’s plans to mine seabed minerals in Arctic waters remain in limbo after the first licensing round was delayed in December 2024. However, the government maintains that progress will resume soon, with a licensing round tentatively set for 2026.
- Some deep-sea mining companies have faced significant financial struggles due to the delay, with one company going bankrupt and another slashing costs; yet, other firms remain optimistic, insisting the industry’s future is still secure.
- Experts warn that considerable knowledge gaps must be addressed before deep-sea mining can proceed, particularly regarding environmental impacts.
- In Norway, the industry also continues to face heavy opposition from environmental groups, the fishing sector, and several political parties.
Earth Day check-in: Planetary boundaries in peril
Scientists have identified nine planetary boundaries that help regulate a livable planet. Human activities have pushed six of those nine critical Earth systems beyond safe limits, threatening the stability of life as we know it. Mongabay has consistently reported on all nine systems: Climate change, largely driven by fossil fuel emissions, is causing sea level […]
15 years after the BP oil spill disaster, how is the Gulf of Mexico faring?
- The Deepwater Horizon disaster on April 20, 2010, was the largest offshore oil spill in U.S. history, releasing an estimated 4.9 million barrels of oil into the Gulf of Mexico over nearly three months.
- Fifteen years later, the gulf ecosystem shows a complicated picture of both resilience and lingering damage, with some species, like brown pelicans, recovering, while others, like humans, dolphins and deep-sea corals, continue to struggle with long-term health impacts.
- The disaster prompted an unprecedented legal settlement directing billions toward restoration projects, though experts debate whether these funds have been used effectively for ecosystem-scale recovery.
- Climate change remains the “800-pound gorilla in the room,” threatening the gulf’s future resilience, one expert said, with others warning that continued pressure from fossil fuel development, agricultural runoff and other threats could push the system beyond its capacity to recover.
Critically endangered right whales spotted in the Bahamas for first time
Two North Atlantic right whales, among the most at-risk marine mammals, were spotted swimming in the Bahamas on April 15, marking the first time the species has been seen in the nation’s waters. “That moment for me was breathtaking, and I couldn’t fully gather myself. I thought it was fake at first,” Isaac Ellis, a […]
Mangroves mount a fragile green revival in Iraq’s toxic south
- Sea-level rise and upstream damming have worsened saltwater intrusion in the Shatt al-Arab River, pushing brine deep into Iraq’s interior and threatening agriculture, fishing and marshland ecosystems.
- A mangrove-planting project has been launched as a nature-based solution to combat coastal erosion, saltwater intrusion and pollution — threats that not only endanger Basra’s coastline but also the freshwater marshlands farther inland.
- Despite scientific backing and community support, the project faces significant obstacles like untreated sewage and industrial waste, while limited government support further hampers the project’s long-term viability and impact.
Trump opens massive marine protected area to commercial fishing
U.S. President Donald Trump has signed a proclamation allowing commercial fishing in Pacific Islands Heritage Marine National Monument (PIH), a massive marine protected area home to threatened fish, sea turtles and marine mammals. The proclamation says U.S.-flagged vessels may now fish within 50-200 nautical miles (90-370 kilometers) inside PIH’s boundaries. While the proclamation and factsheet […]
Even in death, Indigenous Fijians protect the sea
In the waters surrounding Fiji, an ancient tradition endures. Indigenous (iTaukei) communities have long established designated both freshwater and marine ecosystems where fishing and harvesting are temporarily forbidden in honor of their deceased. Though historically practiced for cultural and spiritual reasons, these aquatic funerary protected areas (FPAs) have inadvertently contributed to sustainable resource management — […]
Plastic-eating seabird chicks show signs of organ failure and cognitive decline
- Seabirds and other marine wildlife are ingesting an increasing amount of plastics as pollution in the ocean rises.
- A recent study finds that sable shearwater chicks that consume high levels of plastics have abnormal levels of certain proteins in their blood, including some that suggest tissue damage, multiple organ failure and cognitive decline, despite showing no signs of obvious ill health.
- Conservationists say the study’s findings in young chicks show plastics could threaten entire populations of sable shearwaters.
- Although the study’s findings are limited to a single species, they raise concern for other marine life, say conservationists, who urge immediate action to reduce marine plastic pollution.
Baby colossal squid recorded for the first time in its deep-sea home
Researchers exploring the deep sea near Antarctica have made the first confirmed recordings of a colossal squid, the world’s heaviest invertebrate, in its natural environment. But the squid captured on camera was just 30 centimeters (12 inches) long — a baby. The recording was made by the U.S.-based Schmidt Ocean Institute on March 9 during […]
Why conservation research findings are rarely surprising
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. “We already knew that.” I frequently receive complaints from readers about findings in scientific papers being commonsense or obvious. And yes, it’s true: science often confirms what we’ve long suspected or seen in practice. By its nature, science […]
In an ancient Javanese sultanate, coastal women battle climate fallout
- The coast of Demak district, the site of the first Islamic sultanate on the island of Java, has been inundated by the sea over decades owing to groundwater extraction and development.
- The erosion of human settlements is likely introducing new risks for women: “Our conclusion is that women and children, as well as poor families, including the elderly and disabled, are the most vulnerable,” a local legal aid nonprofit told Mongabay.
- Globally, around 90% of fish species are either fully exploited or overfished, and climate change is set to worsen the crisis by disrupting fish reproduction as oceans warm and acidify.
Icelandic whaling company calls off fin whale hunt this summer
Iceland’s largest commercial whaling company, Hvalur hf., has said it will not hunt any fin whales in the summer of 2025. In December 2024, Iceland’s government granted Hvalur hf., run by billionaire Kristján Loftsson, a five-year license to hunt 209 fin whales (Balaenoptera physalus) each year between 2025 and 2029. Another whaling company, Tjaldtangi ehf., […]
Fishing rights, and wrongs, cast small-scale South African fishers adrift
- A community of mixed-race families has lived and fished in South Africa’s Langebaan Lagoon since the 1800s.
- Starting with the former apartheid government in the 1970s, a series of conservation-oriented decisions ostensibly aimed at protecting fish stocks have slowly squeezed the number of these fishers allowed to operate in the lagoon.
- The government now says fish stocks have collapsed and it has reduced the number of small-scale fishers operating in the lagoon even further, while allowing recreational fishing to continue unimpeded. For their part, the fishers deny the stocks have collapsed, and blame declining catches on industrial developments.
- One expert likened the three-decade-long exclusion of the Langebaan net fishers to a case of fortress conservation, in which local people are squeezed out of nature and denied access to resources they’ve long used in order to preserve them for elites.
Even the Gulf of Aqaba’s ‘supercorals’ bleached during 2024 heat wave
- Scientists have long considered the corals in the Gulf of Aqaba in the northern Red Sea to be uniquely resilient to extreme temperatures.
- For the first time on record, however, the heat wave of 2024 bleached some of these super-resilient corals in Israeli and Jordanian waters, according to scientists.
- Scientists studying the episode’s severity and extent estimate that perhaps 5% of the corals in their study area in Israeli waters bleached during the oppressive Northern Hemisphere summer; a small fraction died, but most recovered over the relatively cooler months that followed.
- Tackling threats like pollution that could reduce the corals’ ability to withstand extreme heat is the best way to protect them from rising marine temperatures, and scientists say an oil terminal that sits barely half a kilometer from some of the “supercorals” poses an imminent threat.
Seychelles becomes first country to comply with fisheries transparency standard
- Seychelles, an archipelagic nation off the eastern coast of Africa, has become the first country to comply with the Fisheries Transparency Initiative (FiTI) standard that lays down what information about a country’s fisheries sector should be published online by public authorities.
- When it committed in 2016 to becoming FiTI-compliant, Seychelles signed up to provide complete and up-to-date information on its fisheries sector that would be useful not just to policymakers but also to civil society organizations and the public.
- Seychelles’ FiTI-compliant status signals marked improvements in data availability, but it doesn’t guarantee that all the information on the fisheries sector is complete and fully accessible, with experts pointing out that some critical gaps remain.
- For example, fishing access agreements struck between the Seychelles and other governments, industry associations and private companies are now available online, but critics say decision-makers remain unable to evaluate them fully.
Corals recover faster on artificial structures than on natural reefs, study finds
As climate change causes ocean temperatures to rise, coral bleaching events are expected to become more frequent. So, scientists are looking for ways to help coral reefs recover more quickly, and a new study from Japan suggests that artificial structures like breakwaters may be helpful. When oceans become excessively warm, corals can expel the symbiotic […]
Award-winning film highlights lasting damage from X-Press Pearl disaster in Sri Lanka
- “This Is Not a Pearl,” a short film by Sri Lankan filmmaker Tharindu Ramanayaka, uses a poetic narrative of a pearl oyster mistaking toxic plastic pellets, or nurdles, for her pearl to symbolize the environmental devastation caused by the 2021 MV X-Press Pearl disaster.
- The sinking of the MV X-Press Pearl off Sri Lanka’s coast released 1,680 metric tons of plastic nurdles, marking the world’s largest nurdle spill and triggering long-term damage to marine ecosystems.
- Scientific studies show that toxic chemicals from the spill continue to harm marine life, especially zooplankton like sea urchin larvae and copepods, threatening the broader ocean food web.
- Sri Lanka’s legal efforts for compensation, including cases in both Singapore, where the ship’s operator is based, and the Sri Lankan Supreme Court, remain unresolved; meanwhile, nurdles continue to wash ashore, requiring continuous cleanup efforts nearly four years later.
97-year-old Galápagos tortoise becomes a first-time mom
A pair of Galápagos tortoises in their 90s recently made headlines for successfully producing offspring for the first time. The female tortoise, aptly named Mommy, at Philadelphia Zoo is now considered the oldest recorded first-time mom for the Western Santa Cruz Galápagos tortoise (Chelonoidis porteri), at the age of 97. Mommy, who has been with […]
In Panama, Indigenous Guna prepare for climate exodus from a second island home
- The island of Uggubseni, located in Panama’s Guna Yala provincial-level Indigenous region, spent the month of February participating in region-wide celebrations to mark the centenary of a revolution in which the Indigenous Guna expelled repressive Panamanian authorities and established their autonomy in the region.
- Though the intervening century has left the Guna’s fierce independence undimmed, new existential threats now face Uggubseni: Accelerating sea level rise due to human-caused climate change and overpopulation.
- A consensus now exists among Uggubseni residents that moving inland is necessary; but it remains unclear whether the government will be able to deliver the necessary funding and support.
- Although 63 communities nationwide are at risk of sinking due to climate change, there’s only one other model for climate relocation: In June 2024 the Panamanian government relocated around 300 families from Gardi Sugdub, another island in Guna Yala, to a new community on the mainland where problems remain rife.
Indonesia bets on ‘reuse’ to curb plastic waste and build a circular economy
- Indonesia is promoting “reuse” as a key solution to its plastic waste crisis, with civil society and the Ministry of Environment launching a “reuse road map” to mainstream practices like refilling and returning containers, aiming to shift focus from recycling to more sustainable waste prevention.
- The country produces 7.8 million metric tons of plastic waste annually, with nearly 5 million tons mismanaged and more than 1 million tons ending up in the ocean, making Indonesia one of the top contributors to marine plastic pollution.
- Experts say reuse is more effective than recycling, but receives far less investment globally; activists warn that reliance on recycling, especially chemical recycling, allows continued plastic overproduction and worsens environmental damage.
- Expanding reuse can also boost the economy, creating jobs in packaging, logistics and cleaning services, while reducing plastic-related harm; however, it requires significant infrastructure, regulatory support and public awareness to scale up.
Dugong numbers plummet amid seagrass decline in Thailand’s Andaman Sea
- Thailand’s dugongs are disappearing fast, reflecting an unfolding crisis in the region’s seagrass ecosystems.
- Seagrass beds on Thailand’s Andaman Sea coast that support one of the world’s most significant populations of dugongs have died off in recent years, creating an increasingly challenging environment for the charismatic marine mammals.
- Scientists point to a combination unsustainable coastal practices and climate change as the main factors driving the decline.
- Government agencies, marine scientists and volunteers are taking emergency steps to save the remaining dugongs, but experts warn their long-term survival in Thailand depends on fixing the root causes of the seagrass loss.
Honduras pays the climate cost as its forests disappear and storms rise
- Despite its high vulnerability to extreme weather events, Honduras continues to clear its forests, seen as one of its best protections against climate change and intensifying storms and hurricanes.
- Between 1998 and 2017, Honduras was the world’s second-most affected country by climate change.
- The biggest driver of deforestation in Honduras is shifting agriculture, responsible for nearly three-quarters of all tree loss, with cattle ranching being a top culprit.
- International organizations focusing on climate adaptation and mitigation are urging the Honduran government to do more to prioritize long-term preparedness, with the country recently making progress in that direction.
As Acapulco’s mangroves disappear, Mexico takes strides to protect its coastal forests
- One of Acapulco’s lagoons has experienced the near-complete loss of its mangroves due to urbanization and hurricanes.
- Another Acapulco lagoon has also lost portions of its mangroves, affecting the local fishing industry.
- Overall, the Mexican state of Guerrero has lost more than half of its mangroves since 1979.
- Mexico’s government is working with international organizations, scientists and local communities to restore the country’s lost mangroves.
122 companies responsible for a third of present day sea-level rise: Study
What’s new: Almost half of global average temperature rise and a third of sea-level rise can be attributed to the “carbon majors,” the world’s 122 largest fossil fuel and cement producers, a recent paper shows. What the study says: Research from U.S.-based science advocacy NGO Union of Concerned Scientists (UCS) used climate-carbon cycle models, and […]
Melting Antarctic ice could weaken world’s strongest ocean current, study warns
The strongest ocean current on Earth circles Antarctica. It’s the primary way water moves between the Atlantic, Pacific and Indian oceans, and helps regulate the global climate. But a new study suggests the Antarctic Circumpolar Current (ACC), which until now has been extremely stable, might begin to slow down in the next 25 years, with […]
Bangladesh witnesses coastal erosion, salinization as tourism crushes a flowering creeper
- Bangladesh’s sandy beaches have been witnessing the disappearance of a once-common flowering vine, the beach morning glory, especially on Cox’s Bazar beach.
- Seashore erosion is now increasing in the region as this plant is supposed to retain soil and protect the beach from erosion.
- Experts and studies indicate the excessive and unchecked tourism in the coastal district as one of the major reasons for this loss.
Study delves into increase in humpback whale sightings in UK and Ireland
Earlier this year, U.K. media reported an increase in humpback whale sightings in British and Irish waters. Between December 2024 and January, The Guardian reported some 17 sightings of humpback whales (Megaptera novaeangliae) from the Isles of Scilly in southwest England. Meanwhile, the nonprofit Sussex Dolphin Project reported more than 50 sightings from Sussex in […]
Global seabed regulator concerned by mining company’s unilateral actions
The International Seabed Authority has expressed concern following reports that the U.S. subsidiary of The Metals Company is seeking deep-sea mining permits from the U.S. instead of waiting for the global regulator’s finalization of a mining code. Mongabay recently reported that The Metals Company (TMC), based in Canada, has started a process to apply for […]
Peruvian fishers sue for additional compensation after big December oil spill
- On Dec. 22, 2024, a pipeline leak at the New Talara Refinery in northern Peru spilled oil into the Pacific Ocean, coating 10 kilometers (6 miles) of coastline in black.
- Three days later, the Peruvian environment ministry declared a 90-day environmental emergency, paralyzing tourism and work for more than 4,000 artisanal fishers.
- Now, more than three months later, the fishers have returned to work on a sea dominated by the oil industry. They say the compensation they received from the refinery owner, state-owned oil company Petroperú, is insufficient and they are seeking more.
- For its part, the company says it has met its commitments.
‘Substantial’ transshipment reforms adopted at North Pacific fisheries summit
- The annual meeting of the North Pacific Fisheries Commission (NPFC), a multilateral body that manages most non-tuna fisheries in the region’s international waters, was held March 24-27 in Osaka, Japan.
- In a bid to deter illegal fishing, the NPFC’s nine members agreed to require independent observers on ships that transfer fish at sea.
- The parties agreed to study the impact of bottom fishing on ocean habitats and to protect two small areas on one seamount. They also increased transparency in the NPFC compliance process and reduced the total allowable catch for two key pelagic species.
Huge iceberg breaks from Antarctica, revealing a rich seafloor ecosystem
A massive iceberg broke off from the George VI Ice Shelf in Antarctica in January, giving researchers a rare opportunity to observe a part of the planet never before seen by humans. Coincidentally, a team of researchers from the Schmidt Ocean Institute in California, U.S., happened to be nearby when the ice spanning 510 square […]
Deep-sea miner TMC seeks U.S. approval, potentially bypassing global regulator
- The Metals Company (TMC) has announced that it is in discussions with U.S. regulators to apply for an exploration license and commercial recovery permit under the Deep Seabed Hard Mineral Resources Act (DSHMRA), a U.S. law that oversees deep-sea mining activities.
- This move could serve as an alternative to TMC seeking approval from the International Seabed Authority (ISA), the U.N.-mandated body overseeing deep-sea mining in international waters, that has previously issued exploration licenses to the company.
- However, legal experts warn that if TMC is able to move forward with its plans, it would be in violation of international law and strain relations with Pacific communities.
- While TMC argues that deep-sea mining is vital for U.S. national security and mineral independence, critics warn of irreversible ecological damage and financial risks.
In Pakistan, sea level rise & displacement follow fisherfolk wherever they go
- Rising sea levels are displacing fisherfolk in Pakistan’s coastal areas, forcing them to move to higher ground, such as Karachi, where they now face saltwater intrusion and other climate impacts.
- For many, this displacement is not just about losing homes, but also cultural heritage, traditions and livelihoods, with women, in particular, losing economic freedom as fishing communities decline.
- The Pakistani government lacks a formal policy for the voluntary migration of climate refugees, and while efforts like mangrove restoration have been attempted, they have not significantly alleviated the fishing community’s problems.
- Karachi is projected to receive 2.3 million climate migrants by 2050, primarily due to rising sea levels, saltwater intrusion, and other climate-related catastrophes.
Panama conducts large illegal fishing bust in protected Pacific waters
- Panamanian authorities seized six longliner vessels on Jan. 20 for fishing illegally in protected waters. They also opened an investigation into an additional 10 vessels that surveillance data showed had apparently been fishing in the area but left by the time authorities arrived.
- The seizures took place in the Cordillera de Coiba, a marine protected area that’s part of the Eastern Tropical Pacific Marine Corridor, which connects several MPAs in four countries. It was the largest illegal fishing bust in the history of Panama’s MPAs.
- The vessels, whose activity is still under investigation, were Panamanian-flagged, meaning they were registered in the country, but the identity and nationality of the owners isn’t clear.
- The surveillance work in the case was done in part through Skylight, an AI-powered fisheries intelligence platform, and was supported by a group of fisheries monitoring nonprofits.

Pirates of the Pacific terrorize artisanal fishers on the Peruvian coast
- For more than 15 years, artisanal fishers in the Tumbes region of northwestern Peru have been plagued by an evil that seems straight out of an adventure book: pirate attacks.
- But this is no fiction: more than 20 fishers have been killed in the past 21 years during pirate attacks.
- To date, no one has been tried or even arrested for these crimes.
- Although the police dismantled a pirate gang in 2018, the situation hasn’t improved significantly, and fishers are forced to pay protection fees to the pirates.
Surgically implanted tags offer rare insight into rehabilitated sea turtles
In 2021, the New England Aquarium in the U.S. state of Massachusetts began surgically implanting acoustic tags in rescued loggerhead sea turtles before returning them to the ocean. Four years on, these tags are providing a rare peek into where rehabilitated turtles travel. “Surgically implanted acoustic transmitters have been used for many years in many […]
How Peruvian cockfighters could tip the scales for endangered sawfish
- In Peru, where cockfighting is not only legal but regarded as an important cultural practice, cockfighters have long brought their roosters to fight wearing sharp spurs fashioned from the “teeth” of sawfish.
- The largetooth sawfish (Pristis pristis), the only sawfish that lives in Peru, is incredibly rare and considered critically endangered.
- Advocates for the species both within and outside the sport have increasingly realized that cockfighting plays a role in preventing or hastening its demise in Peru and are working to eliminate sawfish spurs from the sport.
- Although trade in sawfish parts is now illegal in Peru, times are tough for the country’s artisanal fishers. Experts worry that demand for sawfish spurs could drive more sawfish killings than the species can support.
5 takeaways from the 2022 Repsol oil spill in Peru
- On Jan. 15, 2022, the largest oil spill in Peruvian history occurred when a pipeline broke during the offloading of oil from a tanker to a refinery owned by the Spanish company Repsol.
- 11,000 barrels of crude oil spilled into the ocean off the coast of Callao, near Lima. It sullied miles of beaches, killed untold marine animals and upended the livelihoods of thousands of fishers.
- Three years later, the consequences of the tragedy persist, even as the oil industry’s activities along the coast of Peru continue to cause environmental disasters.
- These are the latest details of the case, which has continued to affect Peru’s marine ecosystem and the fishers who depend on it to survive.
Plastic pollution cuts into fishers’ livelihoods in Ecuador and Peru
- A new study in Peru and Ecuador has found that artisanal fishers are losing revenue due to prolific plastic pollution in the ocean.
- Researchers surveyed 1,349 artisanal fishers in Ecuador and Peru and found that the more waste generated locally, the greater the financial losses.
- This is reflected in the national economy, with losses in Ecuador and Peru’s domestic product from fisheries.
- The study is part of the Pacific Plastic: Science to Solutions initiative, which is represented on an intergovernmental committee currently negotiating a treaty on plastic pollution.
Conservationists, fishing industry find balance on protecting African penguins
Conservation NGOs and commercial sardine and anchovy fisheries in South Africa have reached an out-of-court settlement agreeing to extents of fishing closures around six key African penguin breeding colonies. The agreement, endorsed by the environment minister, was made a court order on March 18. The boundaries of the new fishing closures achieve “the sweet spot […]
‘Fatal Watch’: Interview with documentary makers on fisheries observer deaths
- A new documentary, “Fatal Watch,” shows the dangers of work as a fisheries observer, a job that involves collecting scientific data aboard industrial fishing vessels and documenting compliance with conservation and other rules.
- The film focuses on four cases in which fisheries observers died or disappeared on the job during the last decade.
- “Fatal Watch” also casts a critical eye on the fishing industry as a whole, touching on management and transparency issues that the filmmakers see as intertwined with the observer safety problem.
- The film will premiere in California on March 21 at the Sonoma International Film Festival and play in Washington, D.C., on March 24 at the DC Environmental Film Festival, where Mongabay is a media partner.
World Rewilding Day: Four species bouncing back from the brink of extinction
March 20 marks World Rewilding Day. Established just four years ago by the Global Rewilding Alliance, the day celebrates the herculean effort behind rebuilding ecosystems and reminds us that nature can bounce back. Mongabay has reported on rewilding efforts from Southeast Asia to South America and beyond, with teams restoring habitats and releasing captive-bred species […]
Seal ‘oceanographers’ reveal fish abundance in Pacific Ocean’s twilight zone
- The open ocean’s twilight zone, a vast deep ecosystem rich in fish biomass, is poorly understood because it is expensive and challenging for humans to reach its depths 200–1000 meters (660–3,280 feet) below the surface.
- A new study used northern elephant seals (Mirounga angustirostris) — marine predators that forage in the twilight zone — to help understand fish abundance deep down, both five decades into the past and two years into the future.
- The findings illustrate how apex marine predators, such as elephant seals, can serve as sentinels in understanding how fish abundance cascades through marine food webs.
- Given increased interest in fishing in the twilight zone and the unfolding effects of climate change, seals and other deep-diving marine predators could help keep an eye on changes in the oceans’ depths.
Australia faces inflation, agriculture losses after Cyclone Alfred
The Australian government has warned of impacts to the country’s economy in the wake of Cyclone Alfred that caused massive losses to infrastructure, agriculture and the dairy industries when it struck in late February. The horticultural industry was among the worst hit, with strong winds toppling and damaging hundreds of orchard trees, and floodwaters inundating […]
‘Sham’ federal firings suspended, but NOAA’s future remains uncertain
On March 13, U.S federal Judge James Bredar issued an order requiring the Trump administration reinstate thousands of probationary federal employees recently fired as part of government downsizing. The reinstatement order applies across 18 agencies including the Department of Commerce, which administers the National Oceanic and Atmospheric Administration (NOAA). NOAA, which had already fired roughly […]
USAID funding cuts jeopardize creation of Ghana’s first Marine Protected Area
- The U.S. foreign aid freeze blocks the establishment of Ghana’s first Marine Protected Area (MPA).
- The MPA was being created under the Ghana Fisheries Recovery Activity (GFRA), a USAID-funded program that aimed to restore pelagic fish stocks crucial for the country’s food security.
- Ghana’s small pelagics, consisting mostly of sardines, anchovy and mackerels, make up about 60% of local fish landings and serve as a primary source of protein for almost two-thirds of the country’s population.
- The West African nation depended heavily on U.S. foreign aid to preserve its small pelagic fisheries sector, and without other funding, there could be cascading impacts on its economy.
Caribbean reef sharks rebound in Belize with shark fishers’ help
- Endangered Caribbean reef sharks (Carcharhinus perezi) and other shark species are making a striking recovery in Belize after plummeting due to overfishing between 2009 and 2019, according to recent observations.
- Experts say the establishment of no-shark-fishing zones around Belize’s three atolls in 2021 is what enabled the population boom.
- A remarkable cooperation and synergy among shark fishers, marine scientists and management authorities gave rise to the shark safe havens and led to their success, experts say.
Gas leak from BP platform off West Africa worries fishermen, environmentalists
In January, U.K. oil giant BP announced it had started producing gas from the Greater Tortue Ahmeyim (GTA) project, a natural gas production platform it operates off the coast of Mauritania and Senegal. A month later, Mauritanian media reported that a gas leak had been detected at one of the wells. In a statement shared […]
To save a Honduran reef, locals craft custom gear and hunt invasive lionfish
Without a natural predator, invasive lionfish, which damage coral reefs, have become widespread throughout the Caribbean over the last several decades. To prevent further harm off the northern coast of Honduras, locals have resorted to crafting their own spears to effectively and safely hunt lionfish, reports Mongabay contributor Fritz Pinnow. Julio San Martín Chicas, program […]
Whale songs rise and fall with food supply, study finds.
Each year, during summer and fall, large groups of baleen whales gather off the coast of California, U.S., to feast on krill and fish before heading south to breeding areas in the tropics. It’s a crucial time for whales to fatten up, and a new study suggests some whale species announce an abundance of food […]
Flash floods, blackouts and a ‘sharknado’ as Cyclone Alfred lashes Australia
Heavy rainfall and flooding damaged homes and vehicles in Australia, with locals even reporting shark sightings in inland canals. Cyclone Alfred formed over the Coral Sea on Feb. 22, NASA Earth Observatory reported. It intensified for a week offshore causing heavy rainfall along the coast even before making landfall in Australia on March 8. The […]
Scientists identify more than 800 new species in global Ocean Census

Liberia to start industrial shrimp fishing, worrying artisanal fishers
- Liberia plans to expand industrial bottom trawling in the country by authorizing a new fishery for high-value shrimp.
- However, the government has released few details about the plan, including how much shrimp it will allow the new fishery to exploit, when the trawling would begin, or how it would be regulated.
- The country’s umbrella organization for artisanal fishers casts the move as a threat to the livelihoods, safety and food security of Liberia’s more than 57,000 artisanal fishers, as well as to the country’s marine life.
‘Misguided & lazy’ staff cuts at NOAA will hurt global science, experts warn
The Trump administration recently fired roughly 800 probationary employees from the U.S. National Oceanic and Atmospheric Administration (NOAA). Former NOAA workers warn that these cuts will have global repercussions, affecting nations and industries that rely on NOAA’s freely available data. NOAA collects and shares data, from the depths of the ocean to outer space and […]

From Kenya to Madagascar, massive effort aims to put seagrasses on the map
In 2019, scientists set out to map the extent of seagrass in Seychelles, an island nation off the eastern coast of Africa. There, they hit upon a startling number: More than 90% of the country’s “blue carbon,” or the carbon stored in marine ecosystems, is contained within seagrass meadows. Under the Large-scale Seagrass Mapping and […]
Illegal sea fence displaces fishers and sparks land scandal near Jakarta
- A property developer installed 30 kilometers (19 miles) of bamboo fencing in the sea near Jakarta, blocking fishers’ access; an investigation revealed it encompassed 280 ocean plots for which title deeds had been illegally issued.
- The fence has forced many fishers to stop working, while coastal farmers have lost their land to the same luxury development; residents also face eviction with no clear alternatives.
- Authorities have sanctioned a handful of individuals from the public and private sectors and started revoking the illegal deeds, but activists are demanding criminal prosecutions against the companies responsible.
- The case highlights weak oversight of Indonesia’s national strategic projects, raising concerns over environmental destruction, loss of livelihoods, and government favoritism toward big developers.
New Zealand blocks tighter trawling rules at South Pacific fisheries meeting
- The South Pacific Regional Fisheries Management Organisation (SPRFMO), a multilateral body that regulates fishing in the vast waters of the South Pacific Ocean, held its annual meeting Feb. 17-21 in Santiago, Chile.
- At the meeting, Aotearoa New Zealand blocked an effort to implement a rule that would reduce bottom trawling, a fishing practice that disrupts the seabed, in areas occupied by vulnerable marine ecosystems.
- Conservationists lambasted New Zealand’s move, while a New Zealand official defended the country’s approach.
- In other meeting news, the parties raised the fishing quota for jack mackerel above scientifically advised limits and, at the same time, moved forward toward adopting a harvest strategy for the stock that could prevent such abrupt quota hikes in the future.
Funerary practices in Fiji protect marine areas while honoring the deceased
- Indigenous (iTaukei) people across Fiji have historically protected their freshwater and marine areas in memory of chiefs and community members who have passed away. These are called aquatic funerary protected areas (FPAs).
- Researchers published a study to shine a light on this sustainable resource management practice, which they say could present a community marine conservation solution in the region but is largely absent from scientific literature and rarely implemented as a strategy.
- FPAs differ in size and practice but can stretch from shoreline to fringing reefs and tend to ban fishing and harvesting of many species for 100 nights after they are declared.
- From 1960 to 2019, communities established a total of 188 FPAs where 44% of FPAs were protected for 100 nights, and 47% protected all resources and associated ecosystems form fishing and harvesting.
India’s fisherwomen getting left behind by blue economy policies
Women make up nearly half of India’s marine fisheries workforce, yet policies to strengthen the country’s blue economy are leaving women behind, reports contributor Priyamvada Kowshik for Mongabay India. India’s draft blue economy policy framework aims to significantly boost the contribution of marine resources to the country’s GDP, and at the same time improve the […]
Concerns of illegal sea turtle trade persist in Bali as police foil smugglers
- Seizures of large consignments of live turtles in northwest Bali in January have raised concerns among conservationists that trade in the protected species may remain pervasive despite recent progress by civil society and law enforcement.
- Six of the world’s seven species of sea turtle live in the waters around Indonesia, the world’s largest archipelago country.
- WWF Indonesia said the scale of the seizures in January indicated that the trade may be to supply turtle meat for consumption, rather than just for Hindu ceremonial uses.
- A 2019 investigation found authorities in Indonesia, Malaysia and Vietnam seized at least 2,354 whole turtles and more than 91,000 eggs from 163 law enforcement operations between 2015 and July 2019.
The U.S. terminated its 30×30 conservation plan but this also presents an opportunity (commentary)
- “We should be proud of the progress that was made over the last years, but conservation priorities have always evolved [to] save the whales, save the rainforest, to today’s focus on climate change and area targets,” and the recent U.S. withdrawal from the global 30×30 conservation initiative won’t change that, a new op-ed argues.
- The U.S.’s 30×30 goal was central to President Biden’s America the Beautiful for All initiative and mobilized federal funding, new protections, and an all-of-government approach to conservation.
- “We should not accept these rollbacks as permanent defeat,” the authors say, but rather as “an opportunity to make our efforts sharper and more effective.” The loss of 30×30 should not be seen as a rejection of conservation values, but as a call to reimagine a conservation strategy that works for more people in more places.

A sheet of black plastic, snagged on a rock 50 kilometers (30 miles) […]
Oil drilling in the mouth of the Amazon – Lula on a course to disaster (commentary)
- Brazil’s president Lula has greatly escalated his pressure for approval of oil drilling in the mouth of the Amazon River since the February 1st election of a senator from the state nearest the proposed oil field as the new president of the National Senate.
- As shown by the 2010 disaster in the Gulf of Mexico when oil spilled out of control for 5 months from a leak at 1.5-km depth, no one has the technology to control a leak at that depth, much less at the 2.88-km depth of the proposed oil field. The economics of opening the new oil field imply that extraction would continue for decades, long past the time when the world must abandon fossil fuels.
- The hypocrisy of Lula’s claims that the oil project will finance an energy transition sacrifices the opportunity offered by COP 30 for Brazil to assume a leadership role in fighting global warming. The disastrous consequences for Brazil if climate change passes a tipping point make Lula´s current course a formula for disaster.

Conservationists suspect fishing nets, increased tourism for sea turtle deaths in Bangladesh
- More than 100 olive ridley turtles were found dead in Bangladesh’s Cox’s Bazar Beach in the last few weeks.
- Conservationists blame the uncontrolled use of fishing nets and increased tourism during the turtle nesting period to have played a key role in the incident.
- The olive ridley’s main nesting grounds are the various islands in the southeastern district, Cox’s Bazar in the Bay of Bengal, and they come to the beaches to lay eggs before returning to the sea.
- Over the last three years, Bangladesh saw there was an increased number of olive ridley turtles and hatchlings thanks to different conservation programs.
Wisdom, the world’s oldest known bird at 74, has a new chick

Illegal seabed dredging surges as Indonesia resumes sand exports
- Reports of unauthorized seabed dredging have surged following Indonesia’s decision to resume sea sand exports in 2023, raising environmental concerns and exposing weak marine law enforcement.
- Officials argue that removing sediment helps ocean health and prevents land buildup, but experts and activists warn the policy contradicts marine conservation efforts and lacks transparency.
- Dredging threatens mangroves, coral reefs, and fish populations, with projected losses to fishing communities far outweighing state revenue and corporate profits.
- Experts urge the government to reinstate the export ban, conduct thorough environmental impact assessments, and allocate funds for ecological restoration and affected communities.
Conservation groups look for new strategies, tech to halt vaquita decline
- Experts believe fewer than 10 vaquita, the world’s smallest porpoise, survive in Mexico’s Gulf of California, also known as the Sea of Cortez, the only place the species lives.
- Illegal fishing has decimated their population, forcing environmental groups to come up with innovative conservation solutions.
- Vaquitas get caught in illegal gillnets that fishermen use to target totoaba, a fish whose swim bladder can go for tens of thousands of dollars per kilo on the international black market.
- Some environmental groups have focused on patrolling vaquita habitats with ships, sonar, radar and drones, while others maintain that dismantling the organized crime groups behind the totoaba trade is a better use of resources.
How a Philippine town is dealing with the fallout of its own popularity
El Nido in the Philippines was once a small fishing town, but promotion on social media over the last decade led to a dramatic influx of tourists. Tourism has helped the local economy, but also resulted in coastal water contamination, Mongabay’s Keith Anthony Fabro reports. Home to 50,000 residents, El Nido welcomed 10 times that […]
Order restored in Indonesia as fishers recapture scores of farmed crocodiles
- On Jan. 13, several hours of extreme rain over Indonesia’s Batam archipelago, a one-hour ferry from Singapore, caused a breach in the perimeter of a large saltwater crocodile (Crocodylus porosus) farm on the east of Bulan Island.
- More than 100 of the stir-crazy predators reportedly escaped in the storm, causing panic among the population while halting local fishing activities.
- Elected representatives in Batam have since called for the farm to be closed, citing tax irregularities.
- The global supply of reptile skins remains concentrated in northern Australia for the fashion industry, which claims to operate high animal welfare standards despite allegations of extensive suffering on farms.
Small-scale fishers’ role in feeding the planet goes overlooked: Study
- A new study found that small-scale fishing accounts for at least 40% of catch worldwide and provides employment for 60 million people, more than a third of whom are women.
- Small-scale fishing could provide a significant proportion of the micronutrient intake for the 2.3 billion people on Earth who live near coastlines or inland bodies of water, the study found.
- More than 60% of small-scale fishing catch in the studied countries came from places where small-scale fishers had no formal rights to participate in management and decision-making processes.
- “We wanted to have a paper that provided key findings at the global level for each of these dimensions, so that it will be clear for governments that small-scale fishing cannot continue to be overlooked in terms of policymaking,” one of the study authors told Mongabay.
Lawsuit is latest push to curb bottom trawling in protected European waters
- The fishing practice of bottom trawling continues in European marine protected areas (MPAs) despite conservation concerns over its destruction of seabed habitats and indiscriminate catches.
- Four NGOs have sued the Netherlands to stop bottom trawling in the Dutch section of Dogger Bank, an MPA in the North Sea, citing its ecological importance.
- Advocacy efforts across Europe, including other lawsuits, have led to some restrictions on the practice, such as the closure of the U.K. section of Dogger Bank to bottom trawling, but most European MPAs remain insufficiently protected, a 2024 study indicates.
- Fishing interests often disagree with the NGOs’ position on bottom trawling in MPAs, saying that regulated bottom trawling can coexist with conservation goals and support communities socioeconomically, and that blanket restrictions risk marginalizing fishing communities without addressing broader environmental challenges like pollution or climate change.
Mass salmon deaths hit Scottish farms as government investigates
- Hundreds of thousands of Atlantic salmon (Salmo salar) died on fish farms in Scottish waters in the final months of 2024.
- Poisonous jellyfish, disease and parasites were behind the mass mortality events, despite major investments by the salmon industry to combat these threats.
- In January, a parliamentary committee concluded an inquiry into the industry, saying it was “disappointed” by the lack of progress on environmental pollution and animal welfare issues.
Unchecked illegal trawling pushes Indonesia’s small-scale fishers to the brink
- Small-scale fishers in Indonesia face declining catches as illegal trawlers deplete fish stocks in near-shore waters, violating exclusion zone regulations.
- Trawling, a destructive fishing method banned in certain areas, is widely practiced due to weak law enforcement, with local authorities citing budget constraints for lack of patrols.
- The impact on traditional fishers has been severe, with daily catches and incomes plummeting, leading to economic hardship, job changes and social issues, such as increased poverty and divorce rates.
- Fishers and advocacy groups are calling for stricter enforcement of fishing laws and government action to protect small-scale fishers’ rights and livelihoods.
The world’s kelp needs help — less than 2% is highly protected
- Kelp forests support a kaleidoscope of biodiversity and perform crucial ecosystem functions, yet they are in trouble globally.
- A recent journal commentary shows that just 15.9% of kelp forests are in protected areas, and only 1.6% of them are in areas with the highest levels of protection.
- The authors said they hope their findings will motivate policymakers to include kelp forests in international conservation targets, such as the “30×30” mandate to protect 30% of Earth’s land and sea by 2030.
Researchers find microplastics for the first time in the Finnish Sámi waters
- Scientists and Indigenous Skolt Sámi knowledge holders have detected microplastics in the lakes and rivers that the Indigenous Sámi communities have used for generations.
- The concentration of microplastics was small, researchers found, but it was still higher than the quantity expected, given that the area is thought to be pristine.
- The average size of the microplastics was 100 micrometers and concentrations ranged from 45 to 423 microplastic particles per cubic meter.
- While the source of the microplastics is unknown, researchers say one of the sources could be from the transboundary pollution accumulated in fish that come from the ocean to the freshwaters for spawning.
Study suggests algal blooms disorient whales, putting them in danger
- Harmful algal blooms (HABs) in the ocean produce toxins that can sicken humans and marine animals.
- A new study has found an increase in large-whale deaths and injuries near HABs on the U.S. East and West Coasts, mainly due to ship strikes and entanglement in fishing gear.
- The authors propose the reason may be that HAB toxins disorient whales, decreasing their ability to avoid ships and fishing gear. However, they say more research is needed to confirm the link.
- They recommend using advanced HAB prediction models to reduce whale deaths by limiting activities like fishing when HABs and whales overlap.
Underwater volcano in Barents Sea reveals diverse marine life, study finds
What’s new: Following the discovery of the underwater Borealis Mud Volcano on the Arctic seabed in 2023, researchers have now confirmed that the methane-spewing volcano is home to a diverse array of marine life thriving in the unique habitat. What the study says: In 2023, scientists from UiT The Arctic University of Norway discovered the […]
As global genetic diversity declines, conservation efforts offer some hope
Genetic diversity within many species is declining globally, according to a recently published study. “Any threat that reduces the size of a population, or which causes a larger population to become fragmented into two or more smaller populations, can cause a loss of genetic diversity,” lead researcher Catherine Grueber, from the Conservation Genetics Specialist Group […]
Over 1,100 dead olive ridley turtles wash ashore in southern India
More than 1,100 dead olive ridley turtles have washed ashore on the beaches of Tamil Nadu state in southern India this month. Most were found near the state capital, Chennai. “I never heard [of] such large numbers of turtles stranded at any beaches of Tamil Nadu at least in the last three decades,” K. Sivakumar, […]
Underwater citizen science reveals the specter of ghost fishing in Thailand
- Teams of scientists and hobbyist scuba divers have assessed the extent of discarded fishing gear on Thailand’s marine wildlife, finding it poses a pervasive threat to a huge range of species.
- Discarded or “ghost” fishing gear comprises 10% of all marine plastic debris in the ocean, persisting for decades and passively catching and killing species from sea snails to whale sharks.
- Thailand is famed for its recreational diving, and efforts are underway to retrieve ghost gear from the ocean and rescue animals found entangled, as well as to work with fishers to help them recycle their old equipment.
- Experts say preventing gear from entering the ocean in the first place is paramount; solutions must extend beyond cleanup and recycling efforts to encompass policy reform, economic incentives, and improved infrastructure.
Marshall Islands protects ‘pristine’ Pacific corals with first marine sanctuary
The Marshall Islands government has announced it will protect an area of the Pacific Ocean described as one of the most “remote, pristine” marine ecosystems on Earth. The 48,000-square-kilometer (18,500-square-mile) marine sanctuary covers two of the country’s northernmost uninhabited atolls, Bikar and Bokak, and the surrounding deep sea, and it is the first federal marine […]
Lessons from successful mangrove forest restoration in El Salvador (analysis)
- Mangrove forests are important coastal ecosystems worldwide, and many areas that have suffered loss of these trees are the focus of restoration projects, but these suffer from a 70% failure rate.
- Not only are they key habitats for numerous organisms from crabs to fish and birds, they also supply a wealth of seafood for local communities.
- That makes community involvement a key aspect of the Community-Based Ecological Mangrove Restoration (CBEMR) method, which focuses on improving local hydrology and topography while removing or reducing mangrove stressors, and encouraging the trees’ natural regeneration.

Salmon farms under fire on U.S. East Coast after being shuttered on West Coast
- An advocacy group has sued the last company in the U.S. still farming salmon in sea cages, citing alleged violations of the Clean Water Act.
- Cooke Aquaculture runs more than a dozen sites in the northeastern state of Maine. The lawsuit accuses the company of illegally discharging pollutants, exceeding limits on effluents and nutrient buildup, and reporting violations.
- The legal action comes the same month that the state of Washington banned industrial salmon aquaculture over environmental concerns, making Maine the only U.S. state where the practice continues.
- Critics argue that netpen salmon farming not only pollutes the marine environment but also threatens wild salmon populations, while requiring the harvest of too much wild fish and krill for feed.
In Panama, major port construction begins at key mangrove site
- The Puerto Barú project, located outside the town of David in the Pacific province of Chiriquí, will be a new industrial port on Panama’s west coast, where channels and lagoons support mangroves, breeding grounds and nurseries for a variety of marine species.
- The project requires dredging a riverbed and increasing maritime traffic of cargo ships, cruise ships and yachts.
- More than 50 conservation groups have organized a “No to Puerto Barú” campaign, but an initial injunction to stop construction was shot down in court.
Fishing boats spotted competing with whales in Antarctica for krill
Nearly all of Antarctica’s iconic wildlife, from penguins to seals and whales, depend on krill, tiny crustaceans that make up the base of the food chain. Krill are also sought after by humans, who scoop them up using massive fishing boats, potentially putting whales in danger, scientists warn. The fishing boats and whales are “going […]

Ogoni women restore mangroves and livelihoods in oil-rich Niger Delta
- After decades of crude oil spills and the introduction of invasive plant species, thousands of hectares of mangroves in the Niger Delta are destroyed, impacting aquatic species and women’s livelihoods.
- Ogoni women from coastal villages, supported by the Lokiaka Community Development Centre, have been at the forefront of reforestation efforts.
- The women have planted 2.6 million mangrove trees since 2018, drawing attention from a government agency that hired them to share their knowledge and plant mangroves for its oil spill rehabilitation project.
- Around 300 women from Ogoni communities have been trained in mangrove reforestation.
Global ocean temperatures set new record in 2024
- Average temperatures across the world’s oceans reached an all-time high in 2024, according to a multi-team study published Jan. 10.
- The temperatures surpassed even those of 2023, which themselves represented a marked uptick over any previous years on record.
- Each of the two main metrics for ocean temperature hit a record high in 2024, while a commonly cited overall metric that accounts for both land and sea temperatures also reached a new high.
- The findings fit with a decades-long trend of ocean heating. The long-term rise is both a result of climate change and a cause of climate change effects like sea-level rise and increased likelihood of extreme weather.

Atlantic puffins are perilously attracted to artificial light, new study shows
- When they make their first journey into the ocean, fledgling Atlantic puffins are prone to being stranded on land, imperiling them. For years, scientists have wondered what leads to these strandings.
- A new study provides experimental evidence to show that artificial light lures young puffins toward land, contributing to strandings.
- The study found pufflings don’t have a strong preference for any particular light source or color. However, once stranded, they move more under darkness and high-pressure sodium lights than under LED lights.
- Reducing artificial lights along the coast and offshore could save puffin lives, say conservationists, as Atlantic puffin populations are decreasing in parts of Europe. It can also save other threatened seabirds, such as Leach’s storm petrel found off Canada’s coast.
We need a North Pole Marine Reserve to secure a healthy future for Arctic waters (commentary)
- In 2024, the cod fishing moratorium on Newfoundland’s Grand Banks was lifted, 32 years after a historically significant ecological collapse of the fish’s population was caused by overfishing.
- The Central Arctic Ocean Fisheries Agreement signed in 2019 provides an example of how to address the threat from such overfishing by using the precautionary principle, international collaboration and science led evaluations of fish stocks.
- The future health of Arctic marine ecosystems can be secured by establishing a North Pole Marine Reserve, a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Climate change fueled record extreme weather events in 2024
Climate change fueled some of the worst extreme weather events on record in 2024, according to a recent report. Researchers at the World Weather Attribution (WWA) and Climate Central reviewed heat waves, droughts, wildfires, storms and floods that struck in 2024, and found that nearly every extreme weather event they studied was “made more intense […]
New evidence spells massive trouble for world’s sharks, rays and chimaeras
- A third of the world’s sharks, rays and chimaeras are threatened with extinction, and their numbers have dwindled since 1970, finds a new IUCN report and a study.
- Overfishing is the biggest threat to these marine fish, halving their populations in five decades, followed by the international trade in shark parts, habitat degradation and pollution.
- Scientists call for immediate actions to prevent extinction, regulate trade and manage shark fisheries to promote sustainability.
South Australia bans fishing of many sharks and rays in its waters
The state of South Australia has banned fishing of several endangered or critically endangered sharks and rays in its waters. In a media release dated Dec. 11, the state government said the new rules prohibit both recreational and commercial fishing of critically endangered species such as the whitefin swellshark (Cephaloscyllium albipinnum), oceanic whitetip shark (Carcharhinus […]
Sunken ships in Sri Lanka’s Colombo attract more fish than coral reefs
- Shipwrecks host more diverse fish assemblages compared with natural coral reefs off the coast of Colombo, Sri Lanka’s commercial capital.
- Research shows that shipwrecks provide more complex structures with various microhabitats, attracting fish and offering both food and safety, making them more appealing than coral reefs.
- Scientists used the diver operated video recording method, in which a diver carries a video camera along a predefined transect, for allowing species identification and quantification later in the laboratory.
- Sri Lankan waters contain 115 known shipwrecks, with the oldest being the Godawaya wreck, dating back to the second century BCE, and they play a significant role in dive tourism.
Road to recovery: Wild animals staging a comeback in 2024
Conservation news is often heartbreaking, with reports of dramatic biodiversity loss globally year after year. But in 2024, there were several reasons for cheer as well, with conservationists finding that certain species, once at the brink of extinction, are making a comeback. Here are five species that researchers confirmed were showing hopeful signs of recovery […]
Marine protection efforts in 2024 were still a drop in the ocean
In 2022, the world agreed at a U.N. biodiversity summit to protect 30% of Earth’s land and water by 2030. While protected areas already account for almost 15% of the planet’s land, protection for the world’s oceans is lagging far behind, at just over 8%. In 2024, several new marine protected areas (MPAs) helped nudge […]
After trial and error, Mexican fishers find key to reforesting a mangrove haven
- David Borbón and his community are working to restore mangroves in a fishing village within Mexico’s El Vizcaíno Biosphere Reserve, one of the country’s largest protected areas.
- The mangroves act as a natural barrier, protecting the coastal community and ecosystems from hurricanes and other severe weather.
- Borbón, who wasn’t formally educated in any science, conducted a series of experiments to find the best method to reforest the area’s declining mangrove forests and settled on a direct sowing technique that replicates natural patterns.
- With the support of his family and community, he has now planted more than 1.8 million mangroves and largely facilitate the recovery of the mangrove ecosystem.
Photos: Top new species from 2024
- Scientists described numerous new species this past year, from the world’s smallest otter in India to a fanged hedgehog from Southeast Asia, tree-dwelling frogs in Madagascar, and a new family of African plants.
- Experts estimate that fewer than 20% of Earth’s species have been documented by Western science, with potentially millions more awaiting discovery.
- Although such species may be new to science, many are already known to — and used by — local and Indigenous peoples, who often have given them traditional names.
- Upon discovery, many new species are assessed as threatened with extinction, highlighting the urgent need for conservation efforts.
Mauritius reopens talks with U.K. on controversial Chagos deal
A U.K.-Mauritius deal recognizing the latter’s claim to the Chagos Islands in the Western Indian Ocean could be in trouble as Mauritius seeks to renegotiate it. The agreement was reached in October, but no formal treaty was signed by the two countries. Following elections in Mauritius in November, the new prime minister, Navin Ramgoolam, ordered […]
Pacific’s ‘Blob’ heat wave killed millions more seabirds than thought: Study
In 2016, scientists became aware of a die-off of common murres, seabirds resembling flying penguins, that were found washed ashore from Alaska to California. A 2020 study estimated, based on an extrapolation from carcasses found on beaches, that roughly 1 million murres may have died, calling it “unprecedented and astonishing,” even “biblical.” However, a new […]
‘These stories deserve to be told’: Shining a light on secretive fisheries managers
In 2024, the U.N.’s climate and biodiversity conferences, COP29 and COP16, drew the attention of more than 3,500 media delegates and 1,000 journalists, respectively. Though these massive global negotiations are consequential for international policy on the environment and have human rights implications, there were also international negotiations this year on managing the majority of the […]
Electrochemical removal of ocean CO2 offers potential — and concerns
- Stripping seawater of carbon dioxide via electrochemical processes — thereby prompting oceans to draw down more greenhouse gas from the atmosphere — is a geoengineering approach under consideration for largescale CO2 removal. Several startups and existing companies are planning projects at various scales.
- Once removed from seawater, captured carbon dioxide can be stored geologically or used commercially by industry. Another electrochemical method returns alkaline seawater to the oceans, causing increased carbon dioxide absorption over time.
- In theory, these techniques could aid in carbon emission storage. But experts warn that as some companies rush to commercialize the tech and sell carbon credits, significant knowledge gaps remain, with potential ecological harm needing to be determined.
- Achieving the scale required to make a dent in climate change would require deploying huge numbers of electrochemical plants globally — a costly and environmentally risky scenario deemed unfeasible by some. One problem: the harm posed by scale-up isn’t easy to assess with modeling and small-scale projects.
Coral destruction for toilet construction: Interview with a Malagasy fisher
- Toamasina, a coastal city in eastern Madagascar, is surrounded by an extensive network of coral reefs that are home to near-threatened species.
- For decades, these reefs have been under threat from an unusual activity: The use of coral in the construction of septic tanks.
- Mongabay spoke with Abraham Botovao, a boat skipper and the president of a local fishers’ association, who has been closely monitoring this trade and its impact on the local marine environment.
- “It frustrates me every time I see them when I’m out fishing, but unfortunately all I can do is watch without being able to do anything,” Botovao said.
Almost extinct Caribbean lizard makes a comeback after island restoration
A tiny lizard found only on one tiny Caribbean island has seen a dramatic 1,500% increase in its population, after just a few years of island restoration efforts. In 2018, researchers estimated there were fewer than 100 individuals of the critically endangered Sombrero ground lizard (Pholidoscelis corvinus) on the small hat-shaped Sombrero Island, part of […]
A port is destroying corals to expand. Can an NGO rescue enough to matter?
- The ongoing expansion of the port of Toamasina in eastern Madagascar is set to destroy 25 hectares (62 acres) of coral reefs.
- Tany Ifandovana, a Malagasy NGO, removed a small portion of these corals before construction began, and transplanted them to a coral island several kilometers away, as a way to ecologically compensate for the losses, at least in part.
- The NGO faces major challenges, including a lack of resources, little support from the port, and locals destroying corals around the island transplant site.
- “As an environmentalist, it hurt my heart to know that these corals were just going to be filled in,” Tany Ifandovana’s vice president told Mongabay. “Something had to be done.”
European Commission to review Greek oil activity permits in whale habitat
The European Commission will reportedly “seek clarification” from Greece about its recent approvals for offshore oil and gas activities in areas critical for threatened whales and sea turtles. That’s according to the NGO ClientEarth, which, alongside WWF Greece and Greenpeace Greece, filed a formal complaint with the European executive body in 2023 alleging that the […]
Shipbreaking pollutes Türkiye’s coast despite European cleanup efforts
- Over the past decade, more than 2,000 ships have been dismantled at shipyards in Türkiye’s coastal town of Aliağa, one of the world’s main destinations for decommissioned vessels.
- Locals and environmentalists alike complain of rampant water and air pollution linked to shipbreaking, among other industrial activities.
- Workers’ unions and activists have also called out substandard working conditions at the yards, recording 11 deadly accidents between 2018 and 2024.
- Efforts by the European Union to promote better practices in some yards by allowing them to dismantle European ships have had a mixed effect, according to workers and experts Mongabay interviewed, encouraging some yards to improve practices without solving the pollution problem.
Scientists, Māori experts uncover new insights into rare spade-toothed whale
- Spade-toothed whales (Mesoplodon traversii) are among the rarest and least-studied whales, partly due to their deep-diving behavior and long periods spent underwater in the vast, underexplored South Pacific Ocean.
- Until recently, only six records of spade-toothed whales had been documented over 150 years, all but one found in Aotearoa New Zealand, a known hotspot for whale strandings.
- The seventh and most recent record, a 5-meter (16-foot) male, stranded in New Zealand in July 2024, was recently dissected by scientists and Māori cultural experts at a scientific research center.
- A key finding was the presence of tiny vestigial teeth in the upper jaw, offering insights into the species’ evolutionary history, with further discoveries anticipated as analysis continues.
Scientists in Bali find what could be the world’s largest coral colony
When a massive coral colony was recently discovered in the Solomon Islands, it was believed to be the largest in the world. Then last week, scientists found an even bigger one in the waters off the Indonesian island of Bali. Coral restoration nonprofit Ocean Gardener announced that Indonesian marine biologists had measured a Galaxea astreata […]
Landmark ICJ climate change hearing concludes; opinion expected in 2025
The world’s top court has finished hearing its largest-ever climate change case. For the first time, 96 countries and 11 international organizations presented their cases before the U.N.’s International Court of Justice (ICJ) from Dec. 2-13, arguing about the obligations of major greenhouse gas-emitting nations in tackling climate change, and the legal frameworks that could […]
‘Shifting baselines’ in Cabo Verde after 50 years of declining fish stocks
- In Cabo Verde, as in many low-income countries in Africa, the historical record of fish catch is incomplete, making it hard to know what’s been lost and what’s required to fully rebuild.
- In a new study, researchers interviewed fish workers to understand how catches have changed over the last five decades, finding evidence of a major decline in volume of catch and maximum size of key species.
- The study also shows that young fishers and fishmongers don’t fully realize the scale of the loss — a case of what scientists call “shifting baselines.”
- Fishing communities on the West African mainland tell a similar story of decline, pointing to the urgency of centering local knowledge when devising fisheries management and conservation policies.
Philippines’ ‘extraordinary’ typhoon season was climate-fueled: Scientists
From late October to November this year, six consecutive tropical cyclones battered the Philippines, affecting 30 million people. Data analyses from two separate organizations now show they were intensified by human-induced climate change. International scientific collective World Weather Attribution (WWA) released a study on Dec. 12 showing that climate change has made conditions conducive to […]
Research vessel E/V Nautilus spots multiple nautiluses for the first time
The crew of the research vessel E/V Nautilus erupted in excited chatter as they watched live video from a remotely operated vehicle traversing the German Channel in the Pacific island state of Palau. “It’s finally happened!” someone could be heard saying as the camera on board the ROV Hercules zoomed in to reveal a lone […]
Time for a ‘moral reckoning’ of aquaculture’s environmental impacts
Aquaculture is often promoted as a solution to declines in wild fish populations, and has outpaced the amount of wild-caught fish by tens of millions of metric tons each year. But it carries its own myriad environmental impacts, to the detriment of both humans and the ocean, says Carl Safina, an ecologist and author. He […]
First-of-its-kind crew welfare measure adopted at Pacific fisheries summit
- The organization that sets fishing rules for a swath of the Pacific Ocean covering nearly 20% of Earth’s surface and supplying half the world’s tuna catch held its annual meeting in Fiji from Nov. 28 to Dec. 3.
- Parties to the Western and Central Pacific Fisheries Commission (WCPFC) adopted a landmark crew welfare measure — the first binding labor rights measure adopted by any of the world’s 17 regional fisheries management organizations.
- The parties, 25 countries plus the European Union, also adopted a voluntary measure to implement electronic monitoring of catches.
- However, they didn’t adopt a proposal to curb potentially dodgy ship-to-ship transfers known as transshipments, or substantive new protections for sharks and seabirds, as NGO observers had hoped.
Wisdom the 74-year-old albatross lays an egg with new mate
Wisdom, the world’s oldest known wild bird, has laid an egg, this time with a new partner. She is a Laysan albatross (Phoebastria immutabilis), or mōlī in Hawaiian, and this is her first egg in four years, the U.S. Fish and Wildlife Service (USFWS) Pacific region said in a statement on X. “She did it […]
How conservation photographer Cristina Mittermeier uses visual storytelling to inspire action
- Cristina Mittermeier, a pioneer in conservation photography, blends art and advocacy to inspire action and amplify often-overlooked voices, particularly Indigenous communities and unsung conservation heroes. Her work emphasizes optimism and solutions over despair.
- Raised in Mexico with a love for nature, Mittermeier transitioned from marine biology to photography after witnessing the devastating impacts of industrial fishing, realizing that visual storytelling could bridge the gap between scientific data and public emotion.
- In a December 2024 exchange with Mongabay founder Rhett A. Butler, Mittermeier shared her philosophy of “enoughness,” advocating for conservation approaches rooted in inclusivity and honoring Indigenous stewardship as a cornerstone of biodiversity protection.
- Through projects like Hope and her organization SeaLegacy, Mittermeier uses her photography as “visual medicine” to galvanize action, spotlight small victories, and inspire youth to reshape humanity’s relationship with the natural world.
After historic 2024 coral bleaching, hope remains for Mesoamerican Reef
- The Mesoamerican Reef, the longest barrier reef in the Western Hemisphere, stretches 1,000 kilometers (620 miles) along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras.
- The latest instalment of the Mesoamerican Reef Report Card, a periodic health assessment, finds that in 2024, the worst coral bleaching event on record reduced the reef’s coral cover.
- Although the overall health of the Mesoamerican Reef remains “poor,” according to the report, its health actually improved for the first time in five years.
- The report attributes this positive development to an increase in fish populations due to effective enforcement of fisheries rules by regional authorities.
Coca-Cola cuts back on reusable plastic pledge
Coca-Cola is reducing its plastic recycling targets from previous commitments, which advocacy groups say is an abandonment of its reuse goals. The beverage giant’s announcement comes just as talks for a global plastic treaty stalled this month. In a statement published Dec. 2 on its website, Coca-Cola said it has updated its voluntary environment goals […]
Colliding icebergs and chirping seals: Polar ocean sounds are reimagined in art-science collaboration
- The United Nations declared the 2020s the UN Decade of Ocean Science for Sustainable Development to highlight the need for public engagement, citizenship, and connection to harness positive change for the world’s seas.
- Art and science collaborations can make the hidden depths of the oceans come alive for people via creative pieces drawing from real marine research.
- Researchers in Germany and artists from around the world united to highlight the sounds of the polar oceans through art projects created with recordings from the Ocean Acoustics Group at the Alfred Wegener Institute.
As Thailand’s blue swimming crabs decline, crab banks offer a sustainable solution
- Fishing of blue swimming crabs in Thailand has historically exceeded sustainable levels, leading to a decline in both the number and size of crabs that fishers were catching.
- Understanding the urgency of recovering the crab population, fishers, government agencies, NGOs and the private sector have rolled out a series of initiatives to make the fishery more sustainable.
- These include seasonal bans on harvesting egg-carrying crabs, restrictions on trawling and certain kinds of fishing gear, and the establishment of crab banks, where egg-bearing females are nurtured, with their hatchlings later released into a secure marine site.
- Fishers and experts welcome the crab banks, but emphasize the need for a “sustainable holistic scheme,” given that a reliance on crab banks alone won’t rebuild blue swimming crab populations.
In Chile, discovery of shallowest red hydrocoral forest yet surprises scientists
- Scientists have discovered massive marine forests in southern Chile’s Kawésqar National Reserve, formed by the red hydrocoral species Errina antarctica.
- These colonies, found at depths ranging from 1.23 to 33 meters (4 to 108 feet), are the world’s southernmost and shallowest known to date.
- Experts emphasize the importance of protecting these fragile ecosystems and hope the newly discovered forests will be considered in the reserve’s management plan.
Traditional fishers in Peru guard the coast from illegal fishing
- In Chimbote, north of Lima in Peru, fishers have been working for years to protect the Peruvian grunt (Anisotremus scapularis), a fish species in high demand for its meat, along a 1.5-kilometer (almost 1-mile) stretch of coast.
- Illegal fishing methods such as explosives have become common in this area, and the authorities have failed to deter them.
- The fishers, who use traditional methods to catch the grunt from shore, keep watch for illegal activities in the area in hopes that the species will not disappear.
Norway kills first round of Arctic deep-sea mining permits amid opposition
Norway has cancelled the first licensing round for deep-sea mining in the Arctic after pressure from activists and a small environmentalist political party. Plans to mine Norway’s seabed minerals were largely expected to sail through with little opposition, as the government eyed the start of commercial mining in 2030. But the country’s Socialist Left Party […]
How are mangrove restoration projects doing? Interview with Tom Worthington
- A new tool aims to help managers of mangrove restoration projects track their progress and measure final outcomes against initial goals.
- The Mangrove Restoration Tracker Tool was developed by the University of Cambridge, WWF and the Global Mangrove Alliance in a bid to streamline global data on mangrove restoration projects around the world.
- Mangroves are crucial ecosystems that serve as carbon sinks and act as a buffer against coastal erosion; however, they’re threatened by deforestation as well as by the impacts of global warming.
Killer whales have found new homes in the Arctic Ocean, potentially reshaping marine ecology
- The vast ice sheets that historically kept killer whales out of the Arctic Ocean are melting as the region rapidly warms.
- Two small, genetically distinct groups of killer whales now live in the Arctic, after migrating from more southern regions of the Atlantic Ocean.
- Killer whales put pressure on the local ecosystem, including Arctic whales important to Indigenous groups.
No deal to curb plastic production as latest negotiations fizzle
Negotiations for a global plastics treaty ended on Dec. 2, without a consensus on how to curb plastic pollution despite its increasing negative impacts on people and nature. The fifth meeting of the U.N. Environment Programme’s Intergovernmental Negotiating Committee (INC-5) in Busan, South Korea was expected to produce a legally binding global treaty covering the […]
Antarctic krill store massive amounts of carbon in the deep ocean, researchers find
- Antarctic krill trap vast amounts of carbon from the atmosphere in the ocean floor through their sinking fecal pellets, a new study reports.
- The annual amount is similar to that stored by “blue carbon habitats” such as mangroves, seagrass and salt marshes, highlighting the importance of protecting krill.
- Global warming, melting ice and overfishing pose threats to krill, say researchers who call for new fishing policies to conserve them.
Teamwork makes the dream work for orcas hunting world’s biggest shark
Orcas, or killer whales, are the apex predator in the ocean when they work together. A new study documents how a pod of orcas is able to hunt and kill the largest fish in the world, the whale shark (Rhincodon typus), which can be twice the size of an individual orca (Orcinus orca), though the […]
PNG climate migrants sail away with native trees to their new home
Residents of the Carteret Islands in Papua New Guinea are on a “green migration,” contributor Thibault Le Pivain reports for Mongabay. The islanders are leaving their homes due to food shortages resulting from environmental degradation and rising sea levels, and sailing to a larger island in the country, taking with them plants that play important […]
Desalination plants proposed for Texas Gulf Coast spur broad opposition
- Corpus Christi is a city on the Texas Gulf Coast located close to water hungry industries in the drought plagued state, attracting multiple proposals to build desalination plants that would turn saltwater into freshwater for plastic manufacturers and other industrial end users.
- Desalination uses a lot of energy but also produces brine, which can be twice as salty as seawater and can contain elevated levels of heavy metals.
- This brine is set to be pumped back into Corpus Christi Bay or further out into the Gulf of Mexico, causing an array of stakeholders from the fishing community to birdwatchers to oppose the ‘desal’ plants.
- The director of one of the grassroots action groups discusses the situation in an interview with Mongabay.
Conservationists see progress for swordfish, problems for sharks at Atlantic fisheries summit
- The International Commission for the Conservation of Atlantic Tunas (ICCAT), which manages a wide range of fish stocks across the entire Atlantic Ocean and adjacent seas, held its annual meeting in Cyprus Nov. 11-18.
- The parties adopted a “harvest strategy” for North Atlantic swordfish and developed harvest strategies for a number of other species that could be adopted in coming years, drawing praise from conservationists.
- They also came to an agreement on tropical tuna management after years of wrangling; the agreement included the loosening of rules governing the use of controversial fish aggregating devices that can lead to overfishing, in a concession to European industry interests.
- Dozens of member nations supported a rule that would have effectively banned shark finning, but Japan and China blocked the effort.
As Sumatra loses mangroves to oil palms, local fishers also suffer
- Interviews in Kwala Langkat, a fishing village in Indonesia’s Langkat district, along the Malacca Strait, suggest fisheries incomes have collapsed after local elites ripped out a mangrove ecosystem to establish a new oil palm plantation.
- In June, Mongabay reported that police had arrested three residents of Kwala Langkat village in connection with alleged criminal damage to a structure used on the oil palm plantation.
- More than a third of the world’s population today lives within 100 kilometers (60 miles) of the coast, a more than 50% increase in absolute terms compared with 30 years ago.
‘Old’ animals offer wisdom and stability, need protection: Study
In many animal societies, elderly individuals are critical contributors to their species’ survival, a new study has found. That’s why wildlife conservation must account for older animals, researchers say. Keller Kopf, lead author and ecologist at Charles Darwin University, Australia, told Mongabay he wanted to counter the idea that “getting old is always a bad […]
Elephant seal colonies in Argentina face long recovery after ‘catastrophic’ avian flu
- Avian flu, also known as H5N1, spread through marine mammal colonies in Argentinian Patagonia in August 2023, nearly doubling the death rate among southern elephant seals in some areas.
- In a recent land survey, researchers found no new cases of the disease among the seals, signaling an end to the outbreak, at least for now.
- But they also found that the total number of elephant seals had decreased by as much as 66% in some areas, the direct result of the high mortality rates during last year’s outbreak.
- Colonies will only recover with undisturbed seasons of breeding and molting, as well as access to abundant food, experts said.
Leaders fail to address overfishing near Europe at ‘fraught’ international meeting
- The North-East Atlantic Fisheries Commission (NEAFC) held its annual meeting in London Nov. 12-15.
- NEAFC is a regional fisheries management organization, a multilateral body that controls fishing in international waters; its remit includes certain fish stocks in the Northeast Atlantic, near Europe.
- Among these, mackerel and herring have been overfished for years, yet NEAFC member countries did nothing to address the issue at the meeting.
- NGO observers have criticized NEAFC and its members for failing to address governance issues they say led to the overexploitation.
Protecting 2.6% of oceans could prevent deadly whale-ship collisions: Study
Ship strikes are a leading threat to large whales, with global shipping routes overlapping 92% of their habitats, a new study finds. But protecting whales in the most dangerous collision hotspots would require action over just 2.6% of the ocean’s surface, researchers conclude, potentially saving thousands of whales with minimal disruption to global trade. The […]
India advances deep-sea mining technology in the Andaman Sea
- The National Institute of Ocean Technology recently conducted an exploratory deep-sea mining trial in the Andaman Sea.
- Even as the International Seabed Authority (ISA), is yet to finalize the mining code for commercial purposes, those with exploratory licenses have been conducting mining trials in international waters.
- The opposition to deep-sea mining, citing environmental impact, is also at an all-time high.
Microplastics are sickening and killing wildlife, disrupting Earth systems
- Animals across the spectrum of life are eating, breathing and ingesting plastics that leach toxic chemicals and have been shown to alter the function of organs and even cells in humans. Petroleum products — mostly oil and natural gas — are plastic’s base ingredient.
- As plastic breaks down to micro and nano size, it easily enters the bodies of all living things. It takes 500-1,000 years for plastic to break down, and scientists now question whether it ever fully degrades.
- Health studies on wildlife are extremely difficult and costly, but plastics are thought to threaten living thing, from zooplankton, insects, rodents, rhinos and frogs to clams, whales, snakes, wildcats and a host of migratory animals.
- Next week, the world’s nations meet to hopefully finalize a U.N. plastics treaty. After a brief unexplained policy flip-flop, the Biden administration continues siding with Russia, Iran and other fossil fuel-producing nations, and with the petrochemical industry, in opposing binding regulations limiting global plastics production.
Scottish salmon farms seek growth despite mounting fish deaths and environmental concerns
- Scotland is the world’s third-largest producer of farmed Atlantic salmon (Salmo salar), after Norway and Chile.
- The industry is seeking to significantly increase production in Scotland, driven by growing export demand.
- However, it faces ethical concerns over mounting fish mortality, as well as environmental concerns about pollution, the proliferation of sea lice affecting wild salmon, and opposition from several local communities.
- Industry members acknowledge the challenge of growing salmon amid rising sea temperatures, but say Scottish salmon farms have made progress in managing sea lice and other health challenges.
The plastics crisis is now a global human health crisis, experts say
- Plastics can contain thousands of different chemicals, many of them linked to cancer and reproductive harm, and many never tested for safety.
- Multiple studies are now finding these chemicals, along with microplastics, throughout the human body, raising alarm among scientists about widespread health effects, including reduced fertility and increased obesity.
- Research points to a correlation between the presence of microplastics and endocrine disrupting plasticizers in the human body and a variety of serious maladies, but tracing a direct causal line is very difficult given the complexity and number of plastics and the industry’s lack of transparency regarding its products.
- Many scientists and nations are calling for a binding plastics treaty to limit global plastic production. But this week the U.S. took a weaker position; it now supports a policy in which nations set their own voluntary targets for reducing production. Negotiations to determine the final treaty language begin at a UN summit in Busan, Korea, running Nov. 25 – Dec. 1.
A father and son duo fight invasive lionfish on a Honduran reef
- Live coral covers 68% of Tela Bay, on the northern coast of Honduras, creating a complex ecosystem that’s part of the wider Mesoamerican Reef system.
- Among stressors including overfishing and coral bleaching due to climate change, is the invasive lionfish — a spectacular-looking, venomous, striped fish native to the Indo-Pacific that, with no natural predators here, is wreaking havoc on marine ecosystems throughout the Caribbean.
- To protect Tela Bay’s embattled coral reef, a local father and son are mounting a single-minded lionfish hunting effort to limit the fishes’ spread, hunting the fish themselves and organizing hunting competitions.
44% of reef-building coral species at risk of extinction: IUCN
Some 44% of the world’s warm-water, reef-building coral species are facing risk of extinction, according to the latest update by the IUCN Red List of Threatened Species. This is a significant increase compared to the last assessment in 2008, when a third were considered threatened. The latest assessment covers all known coral species that build […]
World’s largest known coral — visible from space — found in Solomon Islands
Scientists aboard a National Geographic research vessel recently discovered the largest known coral in the world. The massive coral, which is 34 meters wide (112 feet) and 32 meters (105 feet) long, is visible from space. It’s a coral of the species Pavona clavus, which typically grows to just 2-3 meters (6.5 to 9.8 feet) […]
Mapping ‘gloop and mud’ sheds light on seabed carbon storage
- Two new reports showing the extent of carbon storage in the marine sediments around the coasts of Canada and the U.K. are helping to build the case for greater protection of the seabed, as part of efforts to mitigate climate change.
- They also highlight some of the threats to this underwater carbon sink, particularly sediment disturbance caused by bottom trawling, a fishing method.
- A new project funded by the U.K.’s Natural Environment Research Council is set to investigate whether or not continued disturbance poses the risk of turning the seabed into a source of CO₂.
Coral biodiversity hotspot at risk from fossil fuel expansion, report warns
- A new report warns that the expansion of oil, gas and liquefied natural gas projects in the Coral Triangle region in the Western Pacific risks unleashing more oil spills, direct damage to coral reefs, noise pollution and ship traffic, not to mention greenhouse gas emissions.
- More than 100 offshore oil and gas blocks are currently in production, and more than 450 additional blocks are earmarked for future exploration, according to the report. If these projects are approved, the production and exploration blocks would cover 16% of the Coral Triangle, an area the size of Indonesia, the report states.
- The report notes there is already overlap between oil and gas operations and critical conservation zones, including 16% of the Coral Triangle’s marine protected areas.
- The Coral Triangle is one of Earth’s most biodiverse regions, stretching across the waters of the Philippines, Indonesia, Malaysia, Papua New Guinea, Timor-Leste and the Solomon Islands. It’s home to 76% of all known coral species, as well as numerous endangered marine species.
Local groups drive creation of new Puerto Rico marine protected area
The U.S. territory of Puerto Rico recently gained a new marine protected area off the island’s central north coast. The MPA, named Jardines Submarinos de Vega Baja y Manatí or the Vega Baja and Manatí Underwater Gardens, spans 202 square kilometers (77 square miles) and is the culmination of a 16-year effort by a coalition […]
Peruvian fishers help red sea urchins recover from overfishing
- For 20 years, fishers from the district of Marcona, on Peru’s southern coast, have been recovering populations of red sea urchin, thanks to an alliance with the government.
- According to a monitoring study by the Peruvian Institute of the Sea, there are more urchins in the area where Marcona fishers work than in other areas.
- Part of the success is rooted in the spatial management of coastal areas that the artisanal fishers’ associations are applying; they are pioneers of this practice in the country.
New ‘Cali Fund’ plans to make companies pay for benefiting from nature
A new global fund for conservation seeks to make corporations share part of their profits of benefiting from using genetic data from animals, plants or microorganisms in nature. Named the Cali Fund, the new finance mechanism was born out of the recently concluded United Nations Convention on Biological Diversity summit, or COP16, held in Cali, […]
Court throws out permits for controversial Baja California hotel project
- The Tres Santos hotel project in Baja California Sur will have to conduct new environmental impact studies in order to obtain permits that it failed to comply with when breaking ground nearly a decade ago.
- Over the last decade, residents said the environmental impact became worse than what had originally been described to them. Some wetlands were filled in and rivers and streams were being diverted.
- Earlier this year, a court found that the original environmental impact study didn’t justify the development that was carried out. It should have been rejected and done again before construction even started.
How the oceans fared at the COP16 biodiversity conference in Colombia
- The United Nations Convention on Biological Diversity summit (COP16) took place in Cali, Colombia, from Oct. 21 to Nov. 2.
- Several oceans-related decisions, as well as the formal inclusion of Indigenous peoples and local communities in negotiations going forward, were bright spots at the summit, observers said.
- A key development for the ocean was the agreement, culminating eight years of negotiations, on a protocol for identifying unique areas of the high seas, the two-thirds of the world’s oceans that are international waters, for protection.
- Other important developments included the announcement of new marine protected areas and new funding for ocean conservation.
An ‘ocean grab’ for a property megaproject leaves Jakarta fishers grounded
- On the outskirts of Indonesia’s capital city, farming and fishing communities face displacement due to the planned construction of Pantai Indah Kapuk II, a vast complex of commercial property and mid-range apartments on the northeast coast of Jakarta’s metropolitan area.
- Farmers and fishers told Mongabay Indonesia that the developer had restricted their access to the sea, and acquired land without paying fair compensation for the value of productive trees.
- Indonesia’s fast-growing urban population has led to a housing crunch in several cities across the archipelago, with the national backlog estimated at more than 12 million homes.
- The national ombudsman’s office said no local residents had yet filed a report over land acquisition, while the developers did not respond to requests for comment.

NOAA finds 77% of world’s corals exposed to bleaching-level heat
In 2023, more than three-quarters of the world’s coral reefs were exposed to ocean temperatures that can cause coral bleaching, researchers with the U.S. National Oceanic and Atmospheric Administration (NOAA) report. Roughly 90% of the excess heat from anthropogenic climate change is absorbed by the oceans, making them hotter now than at any point in […]
Indonesia fisheries minister eyes aquaculture expansion under Prabowo
- Indonesia’s new president, Prabowo Subianto, has retained incumbent fisheries minister Sakti Wahyu Trenggono to oversee expansion in productivity in captive fisheries over the next five years.
- Sakti has pledged to revive ailing aquaculture ponds, most of which are located on the northern coast of Java, where numerous village fishing economies are struggling amid depleted near-shore fish stocks and coastal development.
- In July, Indonesia’s then-vice president, Ma’ruf Amin, told a fisheries summit that climate change, biodiversity loss and environmental damage had hindered the output of near-shore fisheries in the world’s largest archipelagic country.
Lesser noddy sighting stirs up birding community in Bangladesh
- In September, near Bangladesh’s Sonadia Island, an ornithologist and a birdwatcher recorded the sighting of lesser noddies, a seabird species never seen in Bangladesh before.
- Lesser noddies are tropical terns known to be confined to the Indian Ocean.
- Experts say it is unknown why lesser noddies traveled to Bangladesh, and predict that they will soon return to their original habitats after this temporary stopover.
COP16 biodiversity meeting recap: Progress made, but finance lags
- The COP16 biodiversity summit ended on a mixed note. Delegates from 177 nations agreed to language saying that companies “should” pay conservation fees for genetic digital sequence information (DSI) from which they profit. Corporate lobbyists ensured this measure was voluntary, but tropical nations could build DSI fees into their laws.
- COP16 delegates also agreed to give Indigenous peoples and local communities a place at the negotiating table regarding conservation and sustainable use of biodiversity, with “fair and equitable” sharing of benefits.
- Oceans got a boost as a coalition of 11 philanthropies pledged $51.7 million to identify and expand marine protected areas in open oceans. The new Tropical Forest Forever Facility (TFFF) also moved toward launch. This novel funding mechanism could offer an estimated $4 billion annually to 70 tropical nations.
- NGOs and large philanthropies identified obstacles that must be cleared to redirect $1.7 trillion in national subsidies that now annually harm biodiversity. On the down side, COP16 utterly missed addressing the failure of wealthy nations to keep financial pledges to protect nature with $20 billion by 2025 and $200 billion by 2030.
Population crash means African penguins are now critically endangered
Africa’s only resident penguin species is now officially critically endangered, according to a recent assessment by the International Union for Conservation of Nature (IUCN). Over the past century, the African penguin (Spheniscus demersus) has suffered precipitous declines in its population. In the mid-1950s, there were an estimated 141,000 breeding pairs of African penguins, or 282,000 […]
Study maps owners of world’s high-seas ships often tied to illegal fishing
For decades, the owners of refrigerated container ships, or reefers, often associated with illegal fishing, have remained in the shadows. Now, a new study has traced 324 companies as the owners of 569 reefer vessels active between 2017 and 2022, identifying the people and countries behind these ships for the first time. Reefers are used […]
‘Don’t call it the high seas treaty’: Ocean biodiversity risks being sidelined in new deal
The global treaty designed for the “objective of the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction,” adopted last year, has more recently gained an inaccurate, but popular, nickname, and lacks independent enforcement, according to some observers. Known officially as the BBNJ agreement (biodiversity beyond national jurisdiction), it has since […]
Startups replace plastics with mushrooms in the seafood industry
- A handful of startups in the U.S., Europe and Asia are helping the seafood industry fight plastic pollution by creating equipment made from fungi.
- Efforts are currently focused on replacing plastic foam, a polluting component of numerous elements of the seafood supply chain, with mycelium, the root-like structure of fungi.
- A company in Maine makes mycelium-based buoys for the aquaculture industry, for example.
- Elsewhere, projects are seeking to create biodegradable mycelium-based coolers for transporting fish.
The Azores creates largest marine protected area network in the North Atlantic
The Azores, an autonomous Portuguese archipelago, has approved legislation to create the largest marine protected area network in the North Atlantic Ocean. Spread across 287,000 square kilometers (about 110,800 square miles), the new marine protected area network covers 30% of the ocean surrounding the archipelago. Half of the MPA network is “fully protected,” while the […]
At COP16, the ocean needs action, not more promises (commentary)
- As delegates to COP16 debate conservation measures like 30×30 initiatives, a new op-ed by the environment director of Bloomberg Philanthropies, Antha Williams, and the founder of Pristine Seas, Dr. Enric Sala, says that protecting our ocean is more than a conservation measure — it’s a lifeline.
- Well-managed and highly protected marine areas (MPAs) help restore ecosystems, ensuring food security and livelihoods for the billions who depend on them, but a new analysis shows that only 8.3% of the world’s ocean is protected in this way, and that most MPAs are either protected weakly or in name only.
- “Ocean protection has never been more urgent. As leaders gather in Cali, they must ensure that ‘protecting our ocean’ means truly protecting it. The 30×30 target will only be meaningful if we protect areas effectively — not just on paper,” they argue.

More krill fishing and no new protected areas for Antarctic seas after latest talks
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) held its annual meeting Oct. 14-25 in Hobart, Australia.
- The international body comprised of 27 members is charged with conserving marine life in Antarctic waters, an area that is changing rapidly due to human-caused climate change.
- In 2009, the CCAMLR pledged to create “a representative network” of marine protected areas in the Southern Ocean, yet negotiations over four proposed MPAs have been at a standstill for years, due to repeated vetoes by the Chinese and Russian delegations.
- Despite a year of interim negotiations, CCAMLR members failed again at the latest meeting to reach agreement on creating any new marine protected areas and rolled back regulation of the burgeoning Antarctic krill fishery.
Bird-watching with drones? Might want to watch your distance, study says
As researchers and wildlife enthusiasts increasingly use drones to watch birds, a new study has come out with guidelines for best drone operating practices that minimize disturbance. “This study represents an important first step in understanding wildlife responses to drones and promoting ethical considerations in the use of new technologies in wildlife monitoring,” Meredith Palmer, […]
Protecting coral reefs boosts fish numbers by 10%: Study
- New research has found that the protection of coral reefs has boosted the amount of fish they harbor by around 10%.
- The study used survey data from about 2,600 reefs with varying levels of protection from overfishing.
- The team then built a statistical model to predict what would have happened if all reefs had not been protected, and the biomass, or collective weight of the resident fish, dropped by more than 10%.
- The scientists note their findings demonstrate that protections like marine protected areas are working and that greater coverage could lead to even more gains in fish biomass.
New abuse allegations hit China ghost ships in Indonesia waters
- In mid-April this year, several Indonesian crew members aboard the China-based Run Zeng 03 fishing vessel jumped into the Arafura Sea following a pattern of alleged mistreatment on board.
- One of those who jumped didn’t survive, while the others were rescued by a fishing boat that happened on the crew members fighting for life in the water.
- Authorities in Indonesia may have missed opportunities to confine boats operated by Donggang Runzeng Ocean Fishing Co Ltd, a Chinese company based in a port on the country’s border with North Korea.
- The Indonesian fisheries ministry’s head of supervision explained in an interview that his history of contact with the manager of the boats’ operator was part of a law enforcement operation.
Debate over Chile’s fisheries law exposes industry influence on fish management
- A new fisheries law is being debated in Chile’s Chamber of Deputies.
- Three members of Congress have recommended more than 200 changes to the proposed law that align with the main arguments put forward by large fishing conglomerates belonging to the country’s main industry group.
- One of these recommendations seeks to remove an article that would limit bottom trawling, a fishing method many scientists criticize due to its impact on marine ecosystems.
- The debate is exposing the industry’s influence on fisheries management in Chile, some experts say.
Polar bears are suffering paw injuries likely driven by the warming Arctic: Study
What’s new At least two populations of polar bears in the high Arctic are developing paw injuries, possibly because of shifting sea ice conditions in a warming environment, according to a new study. Such injuries have not been reported in these areas previously, the study’s authors write. What the study says Between 2012 and 2022, […]
