Remember when everyone in the United States and beyond was not "Going Green"? Well, now you can see where and when the 'green' movement started. The new documentary Earth Days looks back to the development of the modern environmental movement from when it began soon after WWII in the early the 1950s to the first Earth Day celebration in 1970 and the political action thereafter.

Earth Days' features 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. The film is directed by Robert Stone.
