Button, "Give Earth a Chance," 1970

University of Michigan students formed the Environmental Action for Survival Committee (ENACT) in 1969. They created this button to promote a four-day "Teach-in on the Environment," held in March 1970 (before the official Earth Day, April 22, 1970). It was sold to Earth Day advocates who wore it in support of environmental education, direct action to reduce pollution, and regulation to ensure a future for the planet and its inhabitants.
