Deep in Taiwan’s misty mountains, researchers have confirmed the tallest tree in the country: a thousand-year-old fir tree higher than a 20-story building, which they’ve named “the heaven sword of the Da’an River.” Climbers scaled the tree and dropped a measuring tape from the top to the forest floor during the Lunar New Year holiday in January 2023. The tree measured 84.1-meters (276-feet). The findings have been published in Frontiers in Forests and Global Change. A team of ecologists, geologists, remote-sensing specialists, professional climbers and Indigenous people that calls itself the “Taiwan tree seekers” began the search in 2014. “The common characteristics [of the team] are probably that we are all tree lovers and like adventures,” Rebecca Chia-Chun Hsu, lead author from Division of Forest Ecology, Institute of Taiwan Forestry Research, told CNN. ‘The Heaven Sword’, Taiwan’s tallest tree, measures 84.1 meters. Photo courtesy of Steven Pearce. Taiwan is one of the few places on Earth where trees can grow this tall. The island sits where the tropics meet the subtropics, and its mountains host several giant conifer species. The species behind the new record, Taiwania cryptomerioides, is known to the Indigenous Rukai people as “the tree that hits the moon.” Although nearly 60% of Taiwan is covered in forest, loggers cleared much of the island’s old-growth forest between 1912 and 1991. However, its steep slopes were too dangerous to reach, and pockets of ancient forest survived. Still, finding the tallest tree amid the rugged terrain was a task.

COLOMBO — Sri Lanka banned the purchase and use of single-use plastic water bottles in all government institutions effective May 31, under a new government circular that targets reduction of wasteful plastic consumption within the state sector. The move is the latest in a long line of attempts by the island nation to reduce plastic pollution — a crisis that clogs waterways, pollutes beaches, harms marine life, and overwhelms the country’s fragile waste management systems. But environmentalists say the real question is not whether Sri Lanka can announce another ban, but whether it can be enforced. The new directive applies to public institutions and is expected to reduce the routine use of disposable plastic water bottles during government meetings, events, offices and official functions. Authorities are encouraging reusable alternatives and better drinking water infrastructure within public institutions, says Kapila Rajapaksha, the director-general of the Central Environmental Authority (CEA), the state agency mandated to address plastic pollution. Sri Lanka’s plastic problem is growing exponentially. The National Plastic Waste Inventory (NPWI) published in 2024 has estimated the island’s municipal plastic waste generation to be approximately 250,000 metric tons per year. Sri Lanka recycles only about 27,000 metric tons of plastic waste annually, roughly 11% of total plastic waste generated. An estimated 68,000 metric tons, or 27% of plastic waste, remain uncollected and are often burned, buried or illegally dumped. Approximately 101,000 metric tons or 41% of the plastics go unaccounted from the waste management system during collection, transport, sorting and disposal.

PORT HUGHES, Australia — Situated midway along the Great Southern Reef that spans Australia’s southern coastline, the waters off Port Hughes typically teem with life. The coastal hamlet northwest of Adelaide plays host to a multitude of coral, bivalve and fish species. But in late March, the largest and longest harmful algal bloom (HAB) in Australian history arrived to Port Hughes, depleting its waters’ rich biodiversity. The bloom had first appeared elsewhere off the state of South Australia’s coast a year earlier, causing eye and skin irritation and respiratory symptoms among beachgoers. Then, along with waves of acrid-smelling sea foam, scores of dead marine animals began washing ashore. In Port Hughes, the HAB’s impacts were most visible below the surface. The town’s wooden jetty had previously been one of the most consistent locations in South Australia to observe temperate species, said Stefan Andrews, co-founder of the Great Southern Reef Foundation, a conservation advocacy group. But by mid-April, when Mongabay joined Andrews on a dive, the site was drab compared with vibrant photographs taken in February and March. Under the jetty, sponges and corals that had previously adorned its pylons in a brilliantly hued mosaic appeared colorless. Apart from a short-headed seahorse (Hippocampus breviceps) — a “sign of hope,” Andrews called it — little life was visible in the murky waters. The reef, he said, had become quieter, lacking the sounds of snapping shrimp and other creatures that once played in the underwater soundtrack. “There’s a sense of loss when you…This article was originally published on Mongabay

JEJU ISLAND, South Korea — In April 2025, I zipped myself up into a thick wetsuit and inched down a steep, rocky ledge toward the gray-blue water encircling Beomseom, a small island off the southern coast of Jeju Island in South Korea. Then I leapt into the chilly sea and wriggled into my scuba gear while floating on the surface. In the water with me was Sanghoon Yoon, an adviser for Paran Ocean Citizen Science Center, a South Korean civil society group that advocates for the protection of the ocean. That day, Yoon was my scuba dive buddy. Yoon and I sank beneath the dangling legs of snorkelers into a watery realm of rocks and kelp. Once in deeper water, I encountered gelatinous stalks of soft coral. The polyps appeared purple, pink, red, and even orange, depending on the light. The islet of Beomseom off South Korea’s Jeju Island hosts colorful gardens of soft coral. Image courtesy of Paran. Sanghoon Hoon, an adviser to the Paran Ocean Citizen Science Center, dives among  corals in the waters off Jeju, South Korea. Image courtesy of Paran. The soft corals I saw that day were healthy. But in 2024, soft corals around Beomseom Island and other parts of Jeju experienced what scientists are calling a “slumping” event — and what Yoon describes as “melting” — which saw soft corals losing their shape, drooping, and even dying. The event was widely reported in local media and attributed to marine heat as Jeju waters hovered…This article was originally published on Mongabay

ELEPHANT MARSH, Malawi — At 5:30 am, trader Flora Kumilai is squatting before a heap of smoked catfish at Sorjin Market in southern Malawi’s Elephant Marsh, haggling with sellers over the price. “I found gold in fish,” she chuckles as she fills a third cardboard box. “And Elephant Marsh is the mine.” Kumilai, who has traveled here from Malawi’s commercial capital, Blantyre, will spend a week in the area, visiting other fish markets around the marsh until she has 12 of these boxes, around 900 kilograms (1,990 pounds) of smoked fish. Then she will band together with other traders to hire a truck to transport their goods back to Blantyre, 140 kilometers (87 miles) to the north. But for Kumilai, the final destination for her goods is more than 1,500 km (930 mi) away, at a market in Kasumbalesa on the border between Zambia and the Democratic Republic of Congo. She’s been in business for more than a decade now, mostly trading in produce within Malawi and sometimes importing clothes from Tanzania and South Africa for customers in the city. In October 2024, she changed course, when fellow traders introduced her to the cross-border trade in fish. In Kasumbalesa, most of Kumilai’s customers are from the DRC, she tells Mongabay in Chichewa. “They pay in [U.S.] dollars. When we change it on the black market to Malawi kwacha, it gives us a lot of money. That’s how I’m able to pay for my son’s education [at Chandigarh University in India].”…This article was originally published on Mongabay

As South Africa transitions away from coal-fired electricity, hundreds of former coal mines are turning into abandoned dumping sites for waste and polluted water, which a new report warns will continue to contaminate surrounding land and waterways for decades. Nor is the South African government taking action to force mine owners to clean them up, environmentalists told Mongabay. South African law requires mining companies to set aside money to clean up and restore the land after mining ends – either in trusts or through bank or insurance guarantees. But a report by the Centre for Environmental Rights found that none of the 412 coal mines that closed between 2006 and 2023 had enough money set aside to pay for the full cost of rehabilitation. The full extent of the problem is unknown as the government has failed to keep any records of mines that closed in 2008, 2010, 2012, 2013, and 2021, the report said. Mining companies must clean up and rehabilitate mines, pay for the damage, and remain responsible until the government officially signs off on the closure, according to the regulations. But most mines do not keep enough money aside to cover even a fraction of the rehabilitation costs, according to the report, titled “No More Ghost Towns : Lessons From Mpumalanga’s Mine Closure Crisis” and released May 22 in Johannesburg. With more than 100 coal mines and most of the country’s aging coal-fired power stations, the Mpumalanga region is the center of South Africa’s fossil fuel-based power…This article was originally published on Mongabay

BANGKOK — More than 600 residents of Chiang Mai and Chiang Rai provinces embarked May 31 on a roughly 68-kilometer, six-day ‘peace walk’ to demand the Thai government take action on the river pollution crisis that has seen Thai rivers polluted with heavy metals. The ensemble of affected residents, civil society groups, monks and students marched from Tha Ton subdistrict in Chiang Mai to the city of Chiang Rai in northern Thailand, reaching their destination on June 5, World Environment Day. For more than a year, Thailand’s Pollution Control Department has reported dangerous levels of arsenic, mercury, cadmium and other heavy metals in rivers across northern Thailand, with mining operations across eastern Myanmar suspected to be responsible for the pollution. “We are walking because our rivers are slowly dying,” Pianporn Deetes, executive director of the Rivers and Rights Foundation, which helped to organize the peace walk, told Mongabay by phone. “Toxic contamination from unregulated mining upstream is already affecting water, fish, food, livelihoods, and public health. We do not want to wait until more people become sick. This is an emergency.” Pianporn said the walk (42 miles) was about taking collective action to share information, document impacts and build public pressure in a bid to force the government to address the issue, which Pianporn said has, so far, been lacking. “Monitoring has improved, but action has not matched the scale of the crisis,” she said. “We need urgent diplomatic engagement with neighboring countries, stronger health monitoring, transparency, and action to…This article was originally published on Mongabay

Global oil giant Shell continued operating a compromised pipeline in Nigeria’s Niger Delta despite knowing it posed a pollution risk in the surrounding coastal wetland environment, newly disclosed internal company communications reveal. The emails and memos, reviewed by Mongabay, show senior leadership knew of the poor conditions of the 97-kilometer (60-mile) Nembe Creek Trunk Line as early as 2008. Despite concerns it was operating outside technical integrity standards and proposals to shut it down, a top executive decided to keep pumping oil through the line. Carrying 150,000 barrels of oil per day to the export terminal at Bonny Island Rivers state, the Nembe Creek Trunk Line is a critical oil artery in Nigeria. Throughout the years, theft from the pipeline using illegal connections caused spills into the vast mangrove ecosystem of true (Rhizophora sp.) and flowering black (Avicennia sp.) tree species. An internal 2013 Shell document coded such tampered lines as “red,” requiring either their immediate shutdown or immediate action to remove all illegal connections. Locals from the nearby riverine Bille community said the oil spills killed about 2,000 hectares (4,900 acres) of mangrove swamps around the village while impacting an area of 13,200 hectares (32,600 acres). The contaminated waterways and degraded ecosystem, they told Mongabay, killed fish and other aquatic life. Satellite imagery surrounding the village shows massive degradation of the mangroves. “The aquatic life is gone. Our people can no longer go to the river and catch reasonable fish — they can’t even find the fish in the…This article was originally published on Mongabay

Leoncia Ramos has lived her 65 years in the lush Dominican Republic town of La Piñita, but now says she is fearful for her health and wants to leave. She’s among 450 families asking the government and the company behind the Pueblo Viejo gold mine to be relocated because of concerns of pollution from the nearby mine. They allege the site, controlled by Canadian giant Barrick Mining Corp., is harming their health and the environment, and fear that if a tailings dam about a kilometer away were to collapse, it would be disastrous. Ramos’s community has spent 15 years fighting to have its concerns addressed and now says Canada, where Barrick Mining is headquartered, could play a role. In 2019, the Canadian government created an office of an ombudsperson to handle complaints from communities like Ramos’s. But the government has left the role vacant for the past year, and its work has seemingly come to a standstill. Canada is home to about half of the world’s publicly traded mining and mineral exploration companies, with operations both in Canada and overseas, including some of the world’s largest miners, like Barrick Mining. The government created the office of the Canadian Ombudsperson for Responsible Enterprise (CORE) in 2019 to address human rights complaints about Canadian companies’ operations overseas. But the office has now been without an ombudsperson since May 2025, and advocates say its work has stalled at a critical moment, as demand for transition minerals and a changing geopolitical climate are driving…This article was originally published on Mongabay

Since NASA’s Artemis II crew members safely splashed down in the Pacific Ocean on April 10 after their record-setting mission around the Moon, science teams have been busy collecting more data and combing through observations collected on the test flight. Results from these science investigations will help support safe human exploration of deep space and provide a blueprint for how future missions will conduct science on the lunar surface as NASA builds a Moon Base and develops an enduring human presence there.

Postflight crew health, performance data

In the hours, days, and weeks after landing, the Artemis II crew members, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, contributed critical data to help the agency understand how the human body reacts to spaceflight. Collecting this data as soon as possible after landing was important to understand how the body adapts from microgravity to Earth’s gravity. The data will inform NASA’s understanding of how quickly crews can complete mission-critical tasks after landing on a planetary surface like the Moon or Mars, where there won’t be landing support personnel to assist.  

Within a day of splashdown, researchers collected a suite of data for the Artemis II Spaceflight Standard Measures study, which is part of a larger effort across the astronaut corps to gather a baseline set of health measurements on blood pressure, heart rate, eye health, and motor control. Crew members also completed a mini obstacle course, which included lying down, standing up, unfurling a rope ladder, ladder climbing, and more, to assess how their bodies were adapting to Earth’s gravity.

Once the crew returned to NASA’s Johnson Space Center in Houston, researchers guided them through further medical check-ups and tests of motor control. Over the next several days, the crew completed obstacle courses wearing spacesuits offloaded to lunar gravity, which is roughly one-sixth the force of Earth’s gravity. Researchers are now analyzing this data to gain insight into how crews may perform as they adapt to the gravity of a planetary surface.

As part of the Immune Biomarkers study, researchers are comparing blood and saliva samples collected after the Artemis II splashdown with samples collected preflight and during the mission. Among other topics, the study investigates whether and how dormant viruses reawaken in astronauts’ bodies while in space.

Some crew members completed postflight cognition tests and a simulated manual spacecraft docking task to assess motor control for the ARCHeR (Artemis Research for Crew Health & Readiness) study. This, combined with data collected through a wrist-worn device while crew members were in space, is used to understand the effect of space hazards on well-being and performance.

Initial data collections for Artemis II health studies concluded 45 days after splashdown. However, medical teams will continually monitor astronaut health throughout the Artemis II crew members’ lifetimes.

Once this data is processed and anonymized, information will be available for scientists to study the effects of spaceflight via a request to NASA’s Life Sciences Data Archive. The results from this work could lead to new technologies and studies that help predict the adaptability of crews on future missions to the Moon and Mars.

Analyzing astronaut-derived organ chips flown around Moon

Organ chips from NASA’s AVATAR (A Virtual Astronaut Tissue Analog Response) investigation are being analyzed at chip developer Emulate’s laboratory in Boston. The organ chips included bone marrow cells from each Artemis II astronaut. They flew around the Moon with the astronauts, and now researchers are studying these organ chips to determine how deep space radiation and microgravity affect human health at the molecular level.

Scientists are comparing the chips flown aboard the spacecraft to ground controls and crew blood samples using advanced techniques, including single-cell RNA sequencing. The analysis will characterize how organ chips model individual responses to spaceflight, which is data that could allow NASA to send future astronauts’ AVATAR chips ahead on missions to develop personalized medical kits. The researchers plan to share early findings at scientific conferences while full analysis continues.

Lunar imagery, audio for data release

On April 6, the Artemis II crew members studied features on and around the Moon for nearly seven hours during Orion’s closest approach to the lunar surface. Their work was guided by a minute-by-minute observation plan developed by the Artemis II lunar science team.

Scientists are reviewing the data collected from the mission, which includes images, video, and audio files, to release a report of their initial data interpretations later this year. The report will cover observations of impact flashes, variations in color on the lunar surface, and the shape and texture of faults and ridges. The team also will publish a report on how Artemis II lunar science observations were planned, organized, and executed for the benefit of future Artemis missions.

NASA will publish more than 100 science-related audio recordings with transcripts, as well as approximately 11,500 Earth and Moon image and video files from the mission science campaign, with accompanying data. While many of these images already are public, these records will be available through NASA’s Planetary Data System, a public archive of data from all of NASA’s planetary missions. To get the data ready, the team is converting files into standard formats that anyone can easily open and add information to make the data searchable in NASA’s archive for generations to come.

Editor’s note: This article was updated on June 5.

A new study combining NASA satellite observations, ocean surveys, and genetic testing on marine microorganisms found evidence that warming ocean waters may be limiting nutrient availability across much of the global ocean. The researchers report that this nutrient stress affects microscopic marine organisms and could influence marine ecosystems over time.

The research, published June 5 in Science Advances, tracked the condition of phytoplankton, which form the base of ocean food webs. Rather than measuring nutrients like nitrogen, iron, and phosphorus directly, the researchers inferred stress by tracking subtle shifts in the ratio of carbon to chlorophyll in phytoplankton observed from space. When the amount of chlorophyll decreases relative to carbon as seen in satellite data, it’s an indication that the plankton are stressed. 

“As our ocean continues to change, the ability to observe and track ocean conditions through sustained, high quality remote sensing observations has never been more important,” said Laura Lorenzoni, Program Scientist for NASA’s Ocean Biology and Biogeochemistry Program at NASA Headquarters in Washington. “This is fundamental, as plankton communities are the base of the marine food web on which important economic activities rely.” 

The research team combined two decades of data from NASA’s Aqua satellite’s Moderate Resolution Imaging Spectroradiometer (MODIS) sensor with plankton samples collected on research cruises around the world. The approach linked large-scale satellite observations with genetic markers in Prochlorococcus, a tiny but abundant marine microbe that shows signs of nutrient stress in its DNA. The result is a global map revealing where phytoplankton are thriving and where they’re struggling. 

The strongest indications of nutrient stress on plankton appeared in the subtropical gyres, which are vast, relatively calm regions of the Atlantic, Pacific, and Indian oceans. In these areas, a layer of warm surface water stifles the flow of colder water from deeper in the ocean.  

“When the surface of the ocean warms, it generates this very stable situation where a layer of low-density water sits on top of higher-density cold water,” said study coauthor Adam Martiny, an oceanographer at the University of California, Irvine. “You’ve probably experienced that if you’ve ever been to a lake in the summertime—it’s super warm right on the surface, and very cold deeper down when you stick your legs in.” 

This layering blocks the upward flow of nutrient-rich water, limiting the availability of ocean surface nutrients that are crucial for plankton. In the South Pacific, one of the most nutrient-poor regions, a layer of warm surface water contributed to nitrogen and iron shortages, producing the most severe nutrient-related stress that the team discovered. 

But the researchers were surprised to find that parts of the North Atlantic experience less nutrient stress than expected. Although there was evidence of a lack of phosphorus, the impact on microorganisms was comparatively mild. 

That difference may reflect the biology of the organisms themselves. Phytoplankton can partially compensate for phosphorus shortages by recycling phosphorus more efficiently or replacing phosphorus-rich molecules inside their cells. Nitrogen shortages are harder to overcome because nitrogen is crucial for the proteins and cellular machinery required for photosynthesis and nutrient uptake. 

The study revealed that nutrient stress is strongly correlated with seasons and major weather cycles such as El Niño and the Pacific Decadal Oscillation, which lead to warming waters in the Pacific Ocean. During La Niña events, which cool water over a large part of the Pacific, stronger upwelling brought more nutrients to surface waters and reduced stress in some regions. Superimposed on those multi-year cycles, however, was a longer-term trend. 

From 2002 through 2021, average sea-surface temperatures increased across nearly 90% of the ocean area examined in the study. Over the same period, nutrient stress generally intensified, consistent with previous hypothesis that warming oceans may become increasingly stratified and less able to replenish surface nutrients. 

In many nutrient-poor regions of the Southern Hemisphere, however, the researchers found evidence that nutrient stress had not increased as much as expected despite significant warming. They suspect that microbes capable of capturing nitrogen from the air may partially offset the effects of reduced nutrient mixing. 

That finding hints that marine ecosystems may possess more resilience to warming climates than some models predict. It also underscores the complexity of forecasting how ocean biology will respond to continued warming. 

“We have two really powerful tools,” said study coauthor Michael Behrenfeld, a biochemist with Oregon State University in Corvallis, Oregon. The tools include satellite observations and cellular studies. “Both produce big data sets, but they are kind of opposites. We have very detailed data about microscopic phytoplankton … and then we have global coverage with satellites.”   

By combining satellites that monitor the entire ocean with genetic clues carried inside microscopic plankton, the researchers say they are gaining a new way to track biological responses to changing environmental conditions near real time.

Beauty is a curse — at least for the turquoise dwarf gecko of central Tanzania. Between December 2004 and July 2009, demand for this gecko from collectors in Europe boomed, leading to the capture and export of an estimated 40,000 of these striking reptiles from Tanzania. “I remember when I saw them for the first time [at] a fair, it was about 600 euros per specimen,” or about $700, Dennis Rödder, a herpetologist at the Leibniz Institute for the Analysis of Biodiversity Change in Germany, told Mongabay in a video call. “I think within three or four years, the species appeared everywhere across Europe. You could buy them in every pet shop.” Turquoise dwarf geckos (Lygodactylus williamsi) grow to a length of 6-9 centimeters (about 2.5-3.5 inches) and are known from only two small patches of forest in Tanzania: The Kimboza and Ruvu forest reserves. These protected areas cover a combined 34 square kilometers (13 square miles). Adult females have a green-brownish color that mimics the leaves of the trees they live in, but the males’ skins are a vivid contrasting blue, one of the rarest colors in nature, meant to stand out and attract females.

More than a decade ago, conservationists began working to preserve a unique population of desert pampas cats that has adapted to the mangroves of Peru’s northern coast. This small, isolated population roams the San Pedro de Vice dry mangroves, a Ramsar Site and South America’s southernmost mangrove ecosystem. “This is a very unique population, because as far as we know, [it] is the only Pampas cat population that lives in a mangrove [habitat],” Alvaro Garcia, co-coordinator of the Pampas Cat Working Group and the Peruvian Desert Cat Project, told Mongabay in an email. The desert pampas cat (Leopardus garleppi), distinctive for its broad face, ranges along a relatively thin band snaking southward from Colombia through Peru and Bolivia, to northern Chile and Argentina. The species is acclimated to dry conditions, so inhabits deserts, grasslands and dry forests, and isn’t found living in mangroves anywhere else aside from this region of Peru. Dry mangrove forests, also called scrub or dwarf mangrove forests, grow in highly saline soils in upper intertidal zones, so lack regular daily flushing by ocean tides. At first, it was thought the dry mangrove-acclimated cats were faring well: “[I]n the mangrove [habitat], we put cameras out for a week, and we got tons of photos,” whereas in other parts of the felid’s range, conservationists barely capture one desert pampas cat image per month, said Cindy Hurtado, co-coordinator of the Pampas Cat Working Group and the Peruvian Desert Cat Project.

SARLAHI, Nepal — Dhruba Prasai, a farmer from Sarlahi district in Nepal’s southern plains, says he’s exhausted from lack of sleep. Every year, nilgai antelopes, wild boars, deer and Asian elephants raid his fields, and if left unguarded at night, they not only feed on standing crops, but also stored harvest. “There is a forest to the west, and our fields are right next to it,” Prasai tells Mongabay. “The nilgai eat the maize, and the deer can’t even stand the sight of wheat and oat grass, they eat it all. If people stay up at night to guard the fields, they run away; otherwise, they come and destroy everything.” Farmers such as Prasai across Madhesh province, considered the country’s breadbasket because of its fertile land, are struggling with growing crop losses from wildlife, but complex procedures and policy gaps make access to relief, which is already limited, difficult. From mid-July 2024 to mid-July 2025, 14,821 cases of ‘human wildlife conflict’ were reported in Madhesh, according to government figures. A total of 134 people and 457 animals lost their lives. Last year, a wild boar ate three tand (storage racks) of maize stored in Prasai’s house. Although forest authorities told him to get a recommendation letter from the local municipal ward office to apply for relief, he didn’t do it. “I haven’t done it; we simply don’t have the time,” he says. Even those who did fill out the forms around the same time have yet to receive relief, he…This article was originally published on Mongabay

In April this year, two Bryde’s whales washed-up dead-on Dyer Island, a small nature reserve located a few kilometers off the coast of Gansbaai in South Africa’s Western Cape province. Both whales carried severe injuries; their vertebrae had been shattered. “It was very clear that it was [vessel] strikes, because both those whales were snapped in half, and you can also see the propeller marks,” Loraine Shuttleworth, head of research at the Dyer Island Conservation Trust, told Mongabay. Two whale strandings linked to ship strikes in one month alone is an unusually high number, Shuttleworth said. A new risk assessment has linked the increase in risk of ships striking whales to the rerouting of maritime traffic around South African coast. Due to the Houthi rebels attacks on ships traversing the Red Sea, which started in 2023, and the more recent fallout from the blockade of the Strait of Hormuz, many cargo companies have rerouted their vessels around the Cape of Good Hope. With greater shipping traffic comes a growing threat to marine species inhabiting the region: collisions with large, fast-moving vessels. Between December 2023 and December 2024, the number of large vessels traveling through South African waters at average speeds above 15 knots (28 kilometers per hour) has quadrupled, satellite data show. The scale of the increased maritime traffic struck scientist Els Vermeulen from the University of Pretoria’s Mammal Research Institute Whale Unit, on a flight into Cape Town in 2025. “It was a beautiful day, and there were just…This article was originally published on Mongabay

BANGKOK — Seven hundred days after activists from the environmental group Mother Nature Cambodia were imprisoned on charges widely regarded as retaliatory for their activism, 73 international and Cambodian civil society organizations have renewed calls for their unconditional release. After a trial lasting just over a month, 10 activists from Mother Nature Cambodia were sentenced on July 2, 2024, to between six and eight years in prison. Only five of the defendants attended the hearings, which saw Long Kuntha, 28, Ly Chandaravuth, 26, Phuon Keoraksmey, 25, and Thun Ratha, 34, each sentenced to six years behind bars for plotting against the government; fellow activist Yim Leanghy, 36, received an eight-year sentence for both plotting against the government and insulting the king. The five activists who did not attend the trial were sentenced in absentia. The appeals hearing for all 10 convicted activists was slated to take place on June 2, but has been postponed indefinitely by the Phnom Penh Court of Appeals. “The MNC5 are incarcerated in prisons in overcrowded and harsh living conditions, separated from each other and spread out all across Cambodia, hundreds of kilometers away from their families and legal counsel,” wrote the 73 NGOs in an open letter addressed to Prime Minister Hun Manet. “The … NGOs who have signed this letter sincerely request you take immediate action to ensure the unjust convictions of these five activists are reversed either prior to or at their upcoming appeals court hearing in Phnom Penh, and that their freedom…This article was originally published on Mongabay

As offshore wind farms expand rapidly in the global renewable energy transition, scientists are studying how these large marine infrastructure projects affect ecosystems beneath the waves. Research from Wageningen University & Research in the Netherlands suggests that offshore wind may bring both risks and benefits for sharks and rays, known collectively as Elasmobranchii, which are highly sensitive to electromagnetic fields (EMFs). A six-year project called “Elasmopower” examined how EMFs from subsea power cables in offshore wind farms affect bottom-dwelling sharks and rays. These species depend on natural electric and magnetic fields for key behaviors such as navigation, prey detection, habitat use and long-distance movement, particularly in low-visibility environments. The studies conducted as part of the Elasmopower project have been published in four papers, with three additional papers currently undergoing peer review. Sharks and rays have specialized electroreceptors called ampullae of Lorenzini. The jelly-filled sensory canals around the head and snout can detect even extremely weak EMFs from prey and predators, water movement, and the Earth’s geomagnetic field, Erwin Winter, a scientist at Wageningen, told Mongabay. This system is central to hunting and orientation, making Elasmobranchii especially relevant for studying EMF exposure from offshore energy infrastructure, Winter added. Erwin Winter, a researcher with the Elasmopower project, presented findings on offshore wind, electromagnetic fields and bottom-dwelling sharks and rays at the Sharks International 2026 conference in Colombo, Sri Lanka, in May.

The existence of the “polluter pays” principle (PPP) in Bangladesh, at least on paper, dates back to 1992, ever since the country endorsed the Rio Declaration. However, Bangladesh has made little progress in implementing the principle so far. A statement by the incumbent minister for environment, forest and climate change, Abdul Awal Mintoo, saying that regulatory authorities recovered less than half of the total compensation imposed on polluters over the past 16 years, exposed the structural loopholes in environmental governance behind failures in implementing the principle. The minister pointed out that polluters can delay the compensation recovery by applying their right to appeal against the regulatory authorities’ orders. that Mongabay spoke to said that loopholes in the judicial system, weak evidence and economic analysis on pollution, and polluters’ influence must be addressed if the country really wants to implement the PPP. Environmentalist and Dhaka University’s zoology professor Mohammad Firoj Jaman told Mongabay, “Delays in implementation of laws against polluters aggravate environmental pollution, and the hope of reaping the benefits of environmental justice falls flat.” Shanties stand along the bank of Buriganga River in Hazaribagh, Dhaka district, Bangladesh.

CHIRADZULU, Malawi — Diana Sitima’s farm on the outskirts of Malawi’s commercial capital, Blantyre, is both example and an exception. Where neighboring farmers have planted mostly maize for food and for sale in nearby markets, people drive out to buy sweet potato, pigeon peas and vegetables, bananas and avocado, and eggs produced on Sitima’s 3.5-hectare (8.6-acre) property. Sitima started farming in 1993. Unlike her neighbors, farming was a side hustle to begin with: she worked as an office assistant in Blantyre and her husband had a good job with a bank. Over the next seven years, she and her husband took out a series of micro-loans, renting small parcels of land and hiring people from the village to grow tomatoes for sale in the city. Sitima’s efforts went well, and because her family did not have to rely on their harvest for food or an income at that time, she was able to save the money she earned to take a next step. She quit her office job and acquired a farm of her own in Chiradzulu district, 15 kilometers (9 miles) east of the city. “That’s how I made money to be able to buy this land when it was put up for sale in 2006,” she says. While she was still a part-time farmer, Sitima attended several workshops, where she picked up ideas about agroecological farming — an approach combining crops, agroforestry, fish ponds, poultry and livestock, in a self-reinforcing system that protects soil health and reduces the…This article was originally published on Mongabay

Since May 23, more than 200 primates housed at the Lwiro Primates Rehabilitation Center (LPRC) in South Kivu province in the eastern Democratic Republic of Congo (DRC) have been placed under confinement due to the Ebola outbreak. This measure follows the death of a man who tested positive for the virus on May 21. This individual, a resident of Kahungu, located just 2 km (1.2 miles) from the town of Lwiro, where the center is situated, had traveled in early May to neighboring Ituri province. Ituri is the epicenter of the outbreak, which, as of May 27, is linked to more than 200 suspected deaths. A threat for humans and apes The LPRC houses at least 129 chimpanzees and 108 monkeys of various species, including olive baboons (Papio anubis), yellow baboons (Papio cynocephalus), L’Hoest’s monkeys (Cercopithecus l’hoesti), blue monkeys (Cercopithecus mitis), agile mangabeys (Cercocebus agilis) and others. Parrots, turtles and porcupines can also be found there. These primates, rescued from poaching and the illegal wildlife trade, are being kept in confinement even though “for the moment, no cases of Ebola virus transmission from a human to a great ape have been reported,” primatologist Liz Williamson explained in an email to Mongabay. According to the World Health Organization, the Ebola virus is transmitted to humans through close contact with the blood, secretions, organs or other bodily fluids of infected animals.
