The Sierra Club is a grassroots environmental organization that was founded in 1892 by conservationist John Muir. It has influenced environmental thought and policy in the United States since its creation. The Club was established by Muir after he successfully lobbied for the creation of Yosemite National Park with the intentions of extending Yosemite’s borders as well as promote conservation, preservation, and recreation in California. The success of the Sierra Club since then has been immense, and holds over one million members nationwide. Its involvement with the Arctic National Wildlife Refuge includes recurring lobbying to prevent drilling in addition to creating new wilderness regions. Today, the Sierra Club addresses issues such as climate change, renewable energy, urban spaces, environmental justice, and more. Its presence and influence in Washington, D.C. is critical in providing nature a voice.
