Earth Day, celebrated April 22, is a day designed to inspire awareness and appreciation for the Earth’s environment. It was founded by U.S. Senator Gaylord Nelson as an environmental teach-in in 1970 and is celebrated in many countries every year. This date is Spring in the Northern Hemisphere and Autumn in the Southern Hemisphere. [source: wiki]
