The first Earth Day
Senator Gaylord Nelson of Wisconsin proposed a national teach-in on the environment and recruited Denis Hayes to coordinate it. On Wednesday, April 22, 1970, about 20 million Americans — roughly 10% of the population — took part in rallies, clean-ups and teach-ins.
What followed
- 1970: the Environmental Protection Agency opened on December 2, and Congress passed the Clean Air Act of 1970.
- 1972: the Clean Water Act; 1973: the Endangered Species Act.
- 1990: Earth Day went global, with about 200 million people in 141 countries.
- 2016: the Paris climate agreement was opened for signature at the United Nations on Earth Day; 175 parties signed it that day.
