How did Roosevelt's views on preserving wilderness areas differ from Muir's?

He was able to persuade Roosevelt to return Yosemite Valley and the Mariposa Grove to federal protection as part of Yosemite National Park.

Explanation:

John Muir and Gifford Pinchot were two men who held very different ideas about the environment. John Muir believed that the wilderness should be preserved. Gifford Pinchot thought that the environment should be conserved. Both men were leaders in the environmental movement during the nineteenth century.
