Earth Day facts and history
Celebrate Earth Day with these tips for helping our environment.
kids.nationalgeographic.comEarth Day was created to raise awareness of environmental issues and spur political and public action, with the U.S. context often cited as the catalyst in 1970. The idea originated from two parallel efforts: US Senator Gaylord Nelson’s nationwide environmental teach-ins on April 22, 1970, and John McConnell’s global Earth Day concept proposed earlier in 1969. The April 22 date was chosen to maximize campus participation and avoid major holidays, helping broaden the movement across the United States and beyond. Examples of impact include the subsequent creation of the U.S. Environmental Protection Agency and pivotal environmental legislation in the 1970s, which many historians view as the birth of the modern environmental movement.[1][3][7]
