Theodore Roosevelt was good friends with Pinchot and after the earthquake, he felt he was part of the conservationist movement. Although he was on good terms with Muir and went camping for 3 days with him in Yosemite, he felt closer to Pinchot and the conservationist movement.
He argued the conservationist opinion and attempted to persuade the American public.
