| Additional Information | The Environmental Teach-In was held April 22, 1970 as started by Wisconsin Senator, Gaylord Nelson (and a large crew of activists) in reaction to the Santa Barbara oil spill in 1969. Over 20 million people participated in this Teach-In (modeled after the Vietnam War Teach-Ins) and is now merged with what we celebrate as Earth Day. |
