Green Country Sierra Club

Green Country Sierra Club Northeastern Oklahoma's most influential grassroots environmental organization.

Founded by 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 move away from the dirty fossil fuels that cause climate disruption and toward a clean energy economy.
