In working to elevate individual and international support for stewardship of Earth, at the 1969 National UNESCO Conference in San Francisco, John McConnell, may he rest in peace, proposed an Earth Day to celebrate Earth's life and beauty and to show the need for preserving and renewing the threatened ecological balances upon which all life on Earth depends. In September of 1969, Mr. McConnell proposed Earth Day to the San Francisco Board of Supervisors. The proposal won strong support and was followed by an
Earth Day Proclamation by the City of San Francisco. The idea, supported by U. N. Secretary General U Thant, Margaret Mead and many others, spread worldwide. The ringing of the United Nations Peace Bell at the moment of the March Equinox on Earth Day has become a tradition.
