Endangered Species Act Main > Wildlife

The Endangered Species Act is one of America's most effective tools for safeguarding our fish and wildlife heritage.

Thanks to this landmark law, wild salmon still spawn in the rivers of the Pacific Northwest, wolves have returned to Yellowstone, and the bald eagle soars from coast to coast. The ESA has been successful in keeping over 99 percent of all the fish and wildlife under its care from going extinct, but the Bush administration is rushing to gut the law by changing regulations to make it easier for developers to pave and pollute the nation's wildlands and our special places.

Another threat is global warming. How can the world's most fearsome predator be threatened by global warming? Easier than you might think.
