Quote: Earth Day From Wikipedia, the free encyclopedia Jump to: navigation, search Ron Cobb's 1969 Ecology SymbolEarth Day 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 held on April 22, 1970.[1] Earth Day is celebrated in spring in the Northern Hemisphere and autumn in the Southern Hemisphere. Earth Day Network, a group that wishes to become the coordinator of Earth Day globally, asserts that Earth Day is now observed on April 22 on virtually every country on Earth.[2] World Environment Day, celebrated on June 5 in a different nation every year, is the principal United Nations environmental observance.[3] Many communities also celebrate Earth Week, an entire week of environment-related activities, the first of which occurred in Philadelphia in 1970 (starting April 16 and culminating on Earth Day, April 22.)[4]
