Before he died just 100 years ago, John Muir turned the love of nature into a kind of religion. He gave what he called, "the wilderness" a spiritual value. He was instrumental in establishing the National Park System and he was the founding President of the Sierra Club. But can he be called the "patron saint" of the environmental movement as we know it today? Glen MacDonald is Professor of Geography at UCLA, where he holds the John Muir Memorial Chair.
