The Sierra Club: About Us

http://sierraclub.org Welcome to the Sierra Club, the largest and most effective grassroots environmental organization in the U.S. Join us! -

Founded by legendary conservationist John Muir in 1892, the Sierra Club is now the nation's largest and most influential grassroots environmental organization -- with more than two 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 address climate disruption by moving away from the dirty fossil fuels and toward a clean energy economy.
