Earth Day was the brainchild of Sen. Gaylord Nelson of Wisconsin, who helped organize the first Earth Day events in 1970.
Ever since the first celebration, April 22 has served as a day where people can renew their commitment to sustainability and learn more about taking care of the Earth.
The Earth Day Network has more than 50,000 partners in 192 countries. The organization said Earth Day is celebrated by more than a billion people around the globe.
