The First Earth Day

The first Earth Day was a massive success. Over 20 million Americans took part in demonstrations and events across the country, making it one of the largest public gatherings in U.S. history. This grassroots movement helped galvanize support for environmental legislation, including the Clean Air Act and the Clean Water Act.
