Earth Day 2019: Share Your Favorite, Coolest Nature Video
Next Monday, April 22, 2019, the world will mark its 49th Earth Day. The first Earth Day, held on April 22, 1970, was inspired by Wisconsin Senator Gaylord Nelson, who modeled it on the antiwar protests of the late 1960s. The original Earth Day began on university campuses as a national “teach-in” on environmental issues.
