On April 22, 1970, students participated in an massive action declared by Gaylord Nelson, a senator from Wisconsin. Motivated by the recent Santa Barbara oil spill, teach-ins were held at college and university campus across the United States to protest environmental degradation. “Earth Day,” as the event was known, later became a prominent, annual avenue for citizens to discuss important issues affecting both their local communities and the wider world.
