While the publication of Rachel Carson's book Silent Spring in 1962 has been cited by many as the dawn of the environmental movement, the celebration of the first Earth Day in 1970 demonstrated to many that the concern over pollution, overpopulation, and the abuse of our natural resources was no longer the task of a handful of scientists but something that had caught the attention of people all around the world.
Filmmaker Robert Stone offers a historic look at the events leading up to the initial Earth Day event (and what has and hasn't happened to protect the planet since then) in the documentary Earth Days. Stone offers a thumbnail history of the early days of the environmental movement, profiles several of the movers and shakers behind the initial Earth Day event (including Stuart Brand, Rusty Schweickart, Stewart Udall, and Paul Ehrlich), and compares what politicians have promised to do about the environment since 1970 to what has actually taken place. Earth Days received its world premiere at the 2009 Sundance Film Festival. ~ Mark Deming, Rovi
