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

Indigenous Peoples in Voluntary Isolation and Initial Contact (PIACI) in the Yavarí-Tapiche Territorial Corridor, one of the largest contiguous, intact forests in the Amazon and home to the world’s highest concentrations of PIACI, are under threat by extractive and large-scale industrial activities, which pose an existential threat to its inhabitants and the ecosystems they depend on. This is according to a new report co-authored by Earth Insight, the Regional Organization of Indigenous Peoples of the East (ORPIO), the Coordination of the Indigenous Organizations of the Brazilian Amazon (COIAB) and the Interethnic Association for the Development of the Peruvian Rainforest (AIDESEP). The report finds that oil and gas blocks overlap with 10% of the 16-million-hectare (39.5-million-acre) corridor, including almost 1.7 million hectares (4.2 million acres) of intact tropical moist forest, 907,000 hectares (2.2 million acres) of Key Biodiversity Areas and 713,000 hectares (1.8 million acres) of protected areas. “Pressure from hydrocarbons is increasing on the Peruvian side of the Yavarí Tapiche corridor,” Edith Espejo, senior program manager at Earth Insight and author of the report, told Mongabay over WhatsApp messages. “Our report serves as a warning for the irreversible harm that could take place if these oil blocks move into this corridor. Mining concessions within and on the peripheries of the corridor also pose a threat of encroachment and contamination of waterways.” A critical corridor for ecosystems and Indigenous communities The Yavarí-Tapiche Corridor covers Brazil’s western border states of Amazonas and Acre and Peru’s Loreto and Ucayali departments in the Amazon…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

Deep below the ocean surface, at roughly the depth of 130 five-story buildings stacked end to end, a robot has unfurled a protest sign that reads: “LISTEN TO THE SCIENCE!” A Greenpeace remotely operated vehicle (ROV) holds the banner more than 2,300 meters (7,500 feet) below the surface of the Norwegian Sea, in front of a hydrothermal vent field known as Loki’s Castle. “This marks the deepest banner protest in history, to speak for ecosystems that have no voice of their own,” Sandra Schöttner, chief scientist for the Deep Arctic Expedition, Greenpeace International, said in a press release. The protest, carried out on May 27 during Greenpeace’s Deep Arctic Expedition, targeted an area of the Arctic seabed that the Norwegian government opened to deep-sea mining in early 2024 before reversing course under political pressure. Loki’s Castle was discovered in 2008 in the Arctic Ocean between Greenland and Norway. Here in the depths, hot fluid, between 300 and 320 degrees Celsius (572 and 608 degrees Fahrenheit), pours from mineral chimneys on the seafloor. These vents support a rich and unusual community of life, including microbes that resemble the distant ancestors of complex life on Earth. A 2024 study in Scientific Reports documented the animals living around the vents, including five new-to-science species. The authors suggested areas like this along the Arctic Mid-Ocean Ridge should be treated as “vulnerable ecosystems” and protected. In January 2024, the government of Norway opened roughly 281,000 square kilometers (108,000 square miles) of Arctic waters (an area…This article was originally published on Mongabay
