Sierra Club: December 2017
Founded over 125 years ago by John Muir, Sierra Club remains one of the largest environmental non profit organizations to date. The 501(c)(4) organization's 3 million members and volunteers around the United States are dedicated to promoting renewable energy and mitigating global warming among other objectives.
Having helped to pass the Clean Air Act, Clean Water Act, and Endangered Species Act, Sierra Club remains an influential force especially in current times. Modern issues like the diminishing sizes of protected land for the use of Industrialization (Bear's Ear National Monument) make Sierra Club more important than ever.
