Earth Day is an annual event celebrated on April 22. Worldwide, various events are held to demonstrate support for environmental protection.

First celebrated in 1970, Earth Day events in more than 193 countries are now coordinated globally by the Earth Day Network.

Senator Gaylord Nelson of Wisconsin was disturbed that an issue as important as our environment was not addressed in politics or by the media, so he created the first Earth Day, on April 22, 1970.
