Earth Day First earth day was held on April 22, 1970 by Gaylord Nelson. The first Earth Day had participants and celebrants in two thousand colleges and universities, roughly ten thousand primary and secondary schools, and hundreds of communities across the United States. More importantly, it "brought 20 million Americans out into the spring sunshine for peaceful demonstrations in favor of environmental reform." Earth Day activities in 1990 gave a huge boost to recycling efforts worldwide. Earth Day 2000 was the first year that Earth Day used the Internet as its principal organizing tool. Earth Day is now observed on April 22 each year by more than 500 million people and several national governments in 175 countries. The U.S. Fish and Wildlife Service maintains a list of endangered animals and plants. As of July 2008, 609 animals and 744 plants were listed as endangered or threatened.
