The group created by naturalist John Muir in 1892 was <em>Sierra Club</em> Nature Conservancy Audubon Society Habitat for Humanity.
John Muir had co-founded the Sierra Club in 1892 and he was also President of the Environmental Advocacy Organization for more than 20 years.
In the 20th Century,John Muir continued to create history in 1903,when he camped for 3 nights with USA President Theodore Roosevelt and this helped shape the US President's own conservationist policies later on in the coming years.
Because of John Muir's efforts,we have Yosemite National Park,Grand Canyon,King Canyon,Petrified Forest and Mt Rainier National Parks in the form and shape as we know today.
