American Experience - Season 4 Episode 11 Wild by Law
7.50 55 minutes For years there was no federal law to protect the shrinking wilderness from encroaching industry and tourism, until three men dedicated their lives to finding a remedy. Robert Marshall, Aldo Leopold, the prophet of the modern environmental movement, and Howard Zahniser struggled for decades to create a permanent system of federally protected wilderness areas. The fruit of their efforts, the Wilderness Act, passed in 1964.
