Denis Hayes led the organizing effort which involved 20 million Americans celebrating the first Earth Day on April 22, 1970. It led to the creation of the United States Environmental Protection Agency (EPA) and the passage of the Clean Air Act, the Clean Water Act, and the Endangered Species Act. Click here for more info.
