Additionally, here are a few must-know facts about the history of Earth Day:

Senator Gaylord Nelson spearheaded the creation of Earth Day after witnessing an oil spill in Santa Barbara, CA. Under his leadership, the first Earth Day was in 1970.
The first Earth Day sparked an outpouring of environmental activism, and less than six months later, the National Oceanic and Atmospheric Administration (NOAA) and the US Environmental Protection Agency were formed.
Earth Day went global in 1990.
