In spring 2024, the Center for Biological Diversity petitioned the Fish and Wildlife Service to protect Wilson's phalaropes under the Endangered Species Act. These dainty shorebirds, known for spectacular congregations at Western salt lakes like Utah's Great Salt Lake, face imminent collapse due to climate change and other human-caused threats.

The Center for Biological Diversity, a Tucson-based 501c3 nonprofit, uses science, law, and media to protect species and their habitats. Believing human welfare is linked to nature's diversity, it works to secure a future for all life.

Host Jeff Corwin celebrates the Endangered Species Act (ESA), landmark 1973 legislation protecting vulnerable wildlife and ecosystems. The bald eagle, once near extinction, exemplifies the ESA's success, having recovered and now thriving across the U.S.

The ESA also protects sea turtles, with Florida's beaches being globally vital nesting sites. Conservation efforts, like Boca Raton's beachfront parks, are crucial. While only 1 in 10,000 hatchlings survive to adulthood, protecting their habitat allows these keystone species to flourish. All six sea turtle species nesting in America are protected by the ESA.
