Before 1970 there were no legal or regulatory devices to protect the environment. In the spring of 1970, Senator Gaylord Nelson, inspired by the student anti-war movement, created Earth Day as a way to force environmental protection onto the national political agenda. On April 22, 1970, Earth Day was observed by millions of Americans who took to the streets, parks, and auditoriums to rally for a healthy, sustainable environment. Earth Day was a huge success, and in December 1970 Congress authorized the creation of the Environmental Protection Agency to tackle environmental issues.
