EARTH

Earth Day

In 1962, Gaylord Nelson wanted to bring more awareness to the public about the environment.

On April 22, 1970, he established the first Earth Day.

April 22 was chosen because it is the first official day of Spring in the Northern

hemisphere and of Fall in the Southern hemisphere.
