Every year on April 22, the world celebrates Earth Day. But what is Earth Day? Earth Day is an environmental movement started in 1970 by Gaylord Nelson, a senator from Wisconsin and Denis Hayes, a student at Harvard Kennedy School. Hayes was a young activist who was known for the teach-ins he organized on college campuses, and was recruited by Nelson for these efforts. Together, Nelson and Hayes organized a national demonstration to educate people about environmental issues.

According to the National Institute for Environmental Studies, “an astonishing 20 million American participated in the first observance  (of Earth Day) on April 22, 1970.” American Heritage magazine described the event years later as “one of the most remarkable happenings in the history of democracy.” By the end of the year, the Environmental Protection Agency was formed and by 1990, 140 countries around the globe celebrated Earth Day.

Today, more than one billion people celebrate Earth Day in over 193 countries. It remains an opportunity for everyone around the world to come together around environmental topics, such as pollution, deforestation, eliminating plastics in oceans, and so much more.
