ENACT ECOLOGY CENTER, INC. Ann Arbor, Mich.
This button, distributed by the ENACT (Environmental Action for Survival) Ecology Center of Ann Arbor, Michigan, touts one of the popular mantras of environmentalists in the late 1960s and 1970s: Survival. The mounting environmental degradation of this period provoked questions about the future of humanity and concerns about its survival. As part of this movement, the Ecology Center was established one month after the first Earth Day in 1970. This establishment sought to promote environmental awareness, education, and advocacy through endeavors such as recycling programs, community projects, and environmental lobbying.
