Earth Day, celebrated April 22, was founded by U.S. Senator Gaylord Nelson as an environmental teach-in in 1970.

"Rising concern about the environmental crisis is sweeping the nation's campuses with an intensity that may be on its way to eclipsing student discontent over the war in Vietnam… a national day of observance of environmental problems... is being planned for next spring… when a nationwide environmental 'teach-in'... coordinated from the office of Senator Gaylord Nelson is planned..."

The "Green" movement has had its ups and downs since then, from the Solar Thermal heyday of the 80's to the universal solar, wind, and smart-grid movement of today. Since the first Earth Day, the environmental movement has increasingly transformed itself from a largely grassroots, citizen crusade to a professionally-organized and increasing sustainable enterprise. Environmental organizations now employ tens of thousands of full-time employees, including leaders who often make $150,000 or more, as well as a small army of scientists, lobbyists, lawyers and public affairs specialists.

It is readily apparent that the Green movement is no longer a fad or phenomenon. It is a staple in industry and policy - having created its own economy and job classification (the Green-collar Worker). Green is no longer activism; it is a smart way to be more efficient both functionally and financially.

Earth Day is now observed by more than a billion people in 174 countries. It is coordinated by the nonprofit Earth Day Network (EDN) and is considered "the largest secular civic event in the world."

Join us today by turning off the lights, driving a little less, buying a few CFL bulbs, or whatever you can to join the billions around the world in creating a cleaner and more sustainable tomorrow.
