Earth Day History
In 1969, a massive oil spill occurred in Santa Barbara. A U.S. Senator from Wisconsin, Gaylord Nelson, visited the spill site and was inspired to establish the first national Earth Day on April 22, 1970. The first Earth Day saw 20 million Americans take to the streets and parks to express support for the environment. Public support for efforts to improve the environment led to the creation of the U.S. Environmental Protection Agency (EPA) and the passage of the Clean Air Act, Clean Water Act, and Endangered Species Act. Read more about Earth Day’s history. Earth Day is officially April 22 every year, and the month of April is considered Earth Month. See Tips for Clean Air for what you can do for our planet.
