On April 22, 1970, 20 million people took to the streets and college campuses and hundreds of cities to protest environmental ignorance and demand greater protections for our planet. This first Earth Day sparked the passage of major environmental legislation in the U.S. including the Clean Air, Clean Water, and Endangered Species Acts, and the creation of the Environmental Protection Agency.
