On April 22, 1970, demonstrations by an estimated 20 million Americans advocated for a healthy, sustainable environment.
DEC and the Environmental Protection Agency were created the same year as Earth Day and the Clean Air Act was enacted. The Clean Water Act and Endangered Species Act followed in 1972 and 1973.
