Earth Day is the designation of April 22 as a day to inspire awareness and appreciation for the Earth's environment. Earth day was a day founded by U.S. Senator Gaylord Nelson as an environmental teach-in held on April 22, 1970. While this first Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations.[1][2] Earth Day is now coordinated globally by the Earth Day Network,[3] and is celebrated in more than 175 countries every year.[4] April 22 corresponds to spring (season) in the Northern Hemisphere and autumn in the Southern Hemisphere. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues. World Environment Day, celebrated on June 5 in a different nation every year, remains the principal United Nations environmental observance.[5]

Senator Nelson, an environmental activist, took a leading role in organizing the celebration, hoping to demonstrate popular political support for an environmental agenda. He modeled it on the highly effective Vietnam War teach-ins of the time.[6] The proposal for Earth Day was first proposed in a prospectus to JFK written by Fred Dutton.[7] However, Nelson decided against much of Dutton's top-down approach, favoring a decentralized, grassroots effort in which each community shaped their action around local concerns.
