Eco-Heroes: John Muir

John Muir (1838-1914): Born in Scotland but raised in the U.S., Muir was a naturalist and founder of the Sierra Club.  He petitioned Congress to enact the National Parks Bill to establish Yosemite and Sequoia National Parks in California, which led to our current national parks system.  Filmmaker Ken Burns documented Muir’s story in his PBS special, “The National Parks: America’s Best Idea.”
