Today is Earth Day! People in countries around the world will be celebrating our wonderful planet and raising awareness about the environment.
Earth Day is 39 years old this year. The first Earth Day was celebrated on April 22, 1970. With support from Wisconsin senator Gaylord Nelson, a Washington, D.C. environmental group organized an event called the Environmental Teach-In to raise environmental awareness. This event became Earth Day. Earth Day spread from being recognized in cities and colleges in the United States to being observed in places all over the world.
