Founded in 1892 by 182 charter members. The first president of the Sierra Club was John Muir, a writer and one of America's most famous naturalists and conservationists. The Sierra Club is dedicated to preserving and protecting the Earth's natural wonders and resources. Current programs include the fight to protect streams, wetlands, and wilderness from sprawling urban development, preserve and protect wild forests from such things as commercial logging, and help stop the global warming epidemic.
