Every April 22 citizens of over 190 countries throughout the world now take the opportunity to honor Mother Earth and renew their commitment to the environment. Coincidentally (or conspiratorially?), Earth Day also happens to be the Episcopal feast day of conservationist John Muir (and one day after his birthday), the birthday of Arbor Day founder J. Sterling Morton, and the birthday of communist leader Vladimir Lenin!


The creation of the United States Environmental Protection Agency was one of the most important outcomes of the first Earth Day. This agency was established by President Richard Nixon and Congress to repair damage done to the environment and to establish guidelines that would ensure clean water, air, and land for America.

Other landmark legislation inspired by the first Earth Day includes the Clean Water Act, Clean Air Act, and—a few years later—the Endangered Species Act.


EPA’s Earth Day Take Home Kit provides tips you and your family can use to protect your home and environment while celebrating Earth Day.
