Earth Day

Earth Day is an annual event on April 22 to demonstrate support for environmental protection. First held on April 22, 1970, it now includes a wide range of events coordinated globally through earthday.org (formerly Earth Day Network) including 1 billion people in more than 193 countries.

In 1969 at a UNESCO conference in San Francisco, the peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be observed on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later, United States Senator Gaylord Nelson proposed the idea to hold a nationwide environmental teach-in on April 22, 1970, and hired a young activist, Denis Hayes, to be the national coordinator. The name "Earth Day" was coined by the advertising writer Julian Koenig. Hayes and his staff grew the event beyond the original idea for a teach-in to include the entire United States.
