Did you know that next Sunday, April 22nd is International Earth Day? Ever wondered how a day to celebrate the Earth ever got started? This observance arose from the interest of two men to gather national support in America for environmental issues. In 1969 at a UNESCO Conference in San Francisco peace activist John McConnell proposed a day to honor the Earth and the concept of peace. He called for a grassroots demonstration and selected March 21, 1970 (the spring equinox). Wisconsin Senator Gaylord Nelson sanctified the event in a proclamation that was signed by Secretary General U Thant at the United Nations. A month later, a separate Earth Day was founded by Senator Nelson as an environmental teach-in.
