Earth Day was the brainchild of Gaylord Nelson, aUnited StatesSenator from Wisconsin. After seeingthe environmental destruction causedby the 1969 oil spill in SantaBarbara, California, Nelson wanted to find a way to raise public consciousnessof the needfor greaterenvironmental protections. The result was the first Earth Day on April 22, 1970. On that day,over 20 million Americans took part in a variety of rallies(集会）， meetings，demonstrations andactivities ， all targetedat highlighting the need for protecting Earth and our environment for future generations. Thousands of colleges and universities alsoparticipated. Members of different groups learnedthey sharedcommon values.
Earth Day was a tremendous success.It hasnow become a global phenomenon. In 1990，for example, over 200 million people in 141 countries were organized to bring environmental issues,especially recycling, to the forefront of global consciousness.Today,Earth Day campaigns continue to publicize important environmental issues,such asglobal warming, dean energy,and recycling.
