Earth Day / April 22, 2014
Ever wondered how Earth Day started? This observance arose from an interest in gathering national support for environmental issues. In 1970, San Francisco activist John McConnell and Wisconsin Senator Gaylord Nelson separately asked Americans to join in a grassroots demonstration.

The most common practice of celebration is to plant new trees for Earth Day.
