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.

The planet faces a grim future. Author Carolyn Baker highlights rapidly unfolding climate change and the fragile Fukushima reactor situation. Systems thinker Dave Pollard foresees endgames for economic, energy, and ecological systems, any of which could trigger civilizational collapse.

We are in an unfixable predicament, but we retain the choice of how to respond. Carolyn Baker's book, "Collapsing Consciously," explores these themes. (Published Nov 19, 2013)
