The History of Earth Day


In 1969, American senator Gaylord Nelson was flying over the Santa Barbara oil spill and was so shocked by the scale of it that he decided to create a day to help prevent future cases.

Many point to the first Earth Day, held in 1970, as the beginning of modern environmental activism.

Earth Day is now the world’s largest civic event.
