What is Earth Day?

sp Conceived by U.S. Senator Gaylord Nelson (D-WI), the first Earth Day was observed on April 22, 1970, and celebrated by 20 million people who gathered at schools, parks, and houses of worship to show their support for environmentalism. Over 1,500 college and university campuses and 10,000 schools participated by holding special events. The first Earth Day is said to have been the largest public demonstration in U.S. history, involving more than 10 percent of the national population. American Heritage magazine called it “one of the most remarkable happenings in the history of democracy.” In the years since, Earth Day has grown into a worldwide observance, celebrated by tens of millions of people.1
