The April 22 Earth Day, founded by Senator Gaylord Nelson, was first organized in 1970 to promote ecology and respect for life on the planet as well as to encourage awareness of the growing problems of air, water and soil pollution.
Earth Day is a name used for two different observances, both held worldwide annually. While some people celebrate Earth Day around the time of the vernal equinox, others observe the occasion on April 22 each year. Earth Day aims to inspire awareness of and appreciation for earth's environment. It is currently observed in more than 140 countries around the world.
