Jeff Corwin joins conservationists in California to protect pinnipeds, including elephant seals and sea lions. Organizations like the Marine Mammal Care Center and Defenders of Wildlife are crucial in rescuing and rehabilitating these animals, which face severe threats from climate change, overfishing, habitat loss, and plastic pollution.

Corwin assists Dr. Lauren Palmer and Andy Johnson in rehabilitating four malnourished California sea lion pups, one of whom ingested plastic. After critical care, tagging, and weighing, the pups are successfully released back into the wild. This effort underscores the vital role of conservation in giving endangered animals a second chance and addressing environmental challenges for ecosystem health.

Our purchasing decisions can significantly impact the future of imperiled native grasslands, along with the birds and ecosystems they support. In his TEDxFargo talk, Marshall Johnson, Executive Director of Audubon Dakota and VP of the National Audubon Society, highlights how marketplace choices can help farmers and ranchers conserve grasslands through regenerative grazing. He encourages seeking foods that are better for us and the land, making every day our own Earth Day.

For a decade, Johnson's team has built successful rural and urban community-focused habitat programs. His work in the Dakotas aligns farmers, ranchers, grasslands, and birds in win-win scenarios. Audubon's market-based Conservation Ranching Program now enrolls over 2 million acres across 60 ranches, and he leads the largest urban conservation program in the Northern Great Plains.

Marshall's talk was given at a TEDx event, independently organized by a local community. Learn more at https://www.ted.com/tedx.
