Heidi Kritz has dedicated nearly half her life to protecting Alaska's Bristol Bay from the proposed Pebble Mine. This copper and gold project threatens the world's largest salmon fishery, which is vital for the local economy, ecological stability, and native cultures.

Kritz has tirelessly fought the mine, organizing rallies and a letter-writing campaign that gathered over 6,000 voices. She also mobilizes new activists by working with tribal high school students. Her leadership has significantly advanced the decade-long effort to defend Bristol Bay, and she remains committed to this crucial fight.

JP Viñals joined Activists Coming To Inform Our Neighborhood (ACTION) in 2013 to address environmental and social issues in Hunts Point, South Bronx. The neighborhood, home to New York's largest food distribution center, endures 15,000 daily trucks, causing severe air pollution and some of the nation's highest asthma rates.

As ACTION's president, Viñals focused on transforming the defunct 1.25-mile Sheridan Expressway into a vibrant boulevard. This expressway restricts access to the Bronx River and green spaces, forcing heavy truck traffic onto local streets, harming residents and contributing to pollution. ACTION supports a broader campaign to replace it with housing, hospitals, and green areas, leading school presentations and community education efforts.

During an ethnographic research visit to Nepal, Tsechu Dolma learned that Geling villagers in Upper Mustang were struggling with food and water insecurity due to erratic climate patterns. Upon returning to the US, she consulted with Nepalese expats and academics to devise strategies for climate resilience among the region's subsistence farmers.

With funding from the Rubin Foundation and Columbia University, Dolma returned to Nepal to study past development projects. She proposed building a community greenhouse using local materials, an idea unanimously supported by the villagers. To address youth disengagement caused by civil war and environmental degradation, the greenhouse would be built in a school, fostering intergenerational sharing and collaboration.

Dolma hopes the Geling greenhouse will serve as a global model for climate resiliency and local ownership in rural communities.

Marine life has long faced unchecked exploitation. Rapid technological advances have equipped vessels and equipment with unsustainable power and reach, far exceeding nature's ability to maintain marine populations.

If this continues, the consequences for the marine environment and dependent communities will be severe. For more information, visit Greenpeace's oceans campaign.

Fred Kirschenmann, Distinguished Fellow at the Leopold Center for Sustainable Agriculture, asserts that organic farming doesn't automatically equate to sustainability. He advocates for a shift from a "steady state" to "resiliency," noting that "greening up" isn't enough.

Kirschenmann, a third-generation organic farmer and long-time leader, highlights the unsustainable depletion of finite energy (hydrocarbons) and water resources. He warns that technology alone cannot provide substitute solutions. This insight stems from his talk at the Organicology conference.

Fred Kirschenmann, a distinguished leader in sustainable agriculture and an organic farmer, concluded his reflections on agriculture's future at the Organicology conference in Portland, Oregon. He began by addressing the "third elephant in the room": climate change.

Kirschenmann emphasized that climate change is already impacting regions worldwide, citing examples like Australia, China, and California. His insights underscore the urgent need to confront this global challenge within agricultural practices.

Millionaire Doug Tompkins, founder of Esprit, purchased a vast rainforest in Southern Chile to create Pumalin Park, a significant biodiversity reserve. However, his philanthropy faces suspicion

Millionaire Doug Tompkins, founder of Esprit, purchased a vast rainforest in Southern Chile to create Pumalin Park, a significant biodiversity reserve. However, his philanthropy faces suspicion from many Chileans.

Critics, including conservative politician Jaime Orpis, view Tompkins' 100km reserve as a national security threat, linking the Argentine border to central Chile. His anti-development stance also irritates a nation seeking economic growth. Despite calls for him to leave, Tompkins remains committed to protecting the park until the Chilean government assumes its preservation.
