1970 Bay Area Beginning
- Earth Day can trace its beginnings to the City of San Francisco. While attending the National UNESCO Conference in San Francisco in 1969, San Francisco environmental activist John McConnell proposed a global holiday that would celebrate Earth’s life and beauty as well as advance peace. The proposal won strong support locally, resulting in the very first celebration of Earth Day on March 21, 1970. Later that year, McConnell developed an Earth Day proclamation to establish an international Earth Day, which was accepted and signed by the United Nations in 1971.
