NRDC works to safeguard the earth—its people, its plants and animals, and the natural systems on which all life depends. Supporting the NRDC helps protect the air, land, and water from forces of pollution and corporate greed. Your support helps them save wildlife and wild places by sponsoring some of the hardest hitting cases and campaigns in defense of nature.
The Sierra Club is now the nation’s largest and most influential grassroots environmental organization — with three million members and supporters. Our successes range from protecting millions of acres of wilderness to helping pass the Clean Air Act, Clean Water Act, and Endangered Species Act. More recently, we’ve made history by leading the charge to move away from the dirty fossil fuels that cause climate disruption and toward a clean energy economy.
