Earth Day was founded by Senator Gaylord Nelson (D-Wis.) proposed Earth Day April 22, 1970, after the National Environmental Policy Act was signed into law January 1, 1970. Nelson writes 
|“||It was on that day that Americans made it clear that they understood and were deeply concerned over the deterioration of our environment and the mindless dissipation of our resources. That day left a permanent impact on the politics of America. It forcibly thrust the issue of environmental quality and resources conservation into the political dialogue of the Nation.||”|
The first Earth Day was held on the 100th birthday of Vladimir Lenin.
