Today is the 45th annual Earth Day. The first one was April 22nd, 1970 at a time when cities were buried under their own smog and polluted rivers caught fire.
In 1963, Wisconsin Senator Gaylord Nelson began to worry about our planet – the water and air was being polluted. Plants and animals were dying and he wondered why more people weren't trying to solve these problems. It was talked about in Congress. The president made speeches, but not enough people were working on solutions.
