Where did environmental holidays come from?

Environmental holidays started springing up in the late 1960s. Before the sixties, environmentalists weren't sure how they could raise mass public awareness for their ideals. But everything changed after a massive oil spill in Santa Barbara in 1969.

Inspired by the student protests against the Vietnam War, Gaylord Nelson, a U.S. senator from Wisconsin, realized he needed to create that same spirit of energy around the environment. And if he did, he could use his power as a senator to force it on to the national agenda. So he created Earth Day (Apr. 22) as one of the first national days that brought attention to the environment.

By the end of that year, the U.S. Environmental Protection Agency (EPA) was created, and the Clean Air, Clean Water, and Endangered Species Acts were all passed. Inspired by events like these, other environmental organizers started creating their own holidays to draw attention to their special causes.
