We want to focus primarily on resources that connect to Earth Day and illustrate NASA's role in scientific research that is used when making decisions about our environment. We celebrate Earth Day to
bring attention to and raise awareness of how to best protect our planet. Because of the efforts of Earth Day advocates, the Clean Air Act and the Clean Water Act was established as some of the most influential modern environmental laws. Below are some facts about the history of Earth Day!
WHO: Senator Gaylord Nelson of Wisconsin is credited with starting Earth Day.
WHEN: The 1st Earth Day was celebrated on April 22, 1970.
WHAT: 20 million people nationwide attended the first Earth Day festivities. On the 20th Anniversary of Earth Day, 200 million people across the world participated in the celebration!
WHERE: The 1st Earth day was celebrated in major cities across the nation but has now expanded to over 141 different countries!
