Overview: Earth Days looks at the road to April 22, 1970, to the dawn and development of the modern environmental movement through the extraordinary stories of the era’s pioneers — among them Former Secretary of the Interior Stewart Udall, biologist/Population Bomb author Paul Ehrlich, Whole Earth Catalog founder Stewart Brand, Apollo Nine astronaut Rusty Schweickart, and renewable energy pioneer Hunter Lovins. Earth Days is a meditation on man’s complex relationship with nature and an engaging history of the revolutionary achievements and missed opportunities of groundbreaking eco-activism.
