Resources, Wilderness & the Environment

The modern environmental movement became a powerful force in the 1960s. It's built on early 20th-century efforts to conserve the natural world, preserve wilderness, and control pollution. But after World War II the movement was also a response to profound changes in American life. These changes continue today.
