Origins and Historical Context of Earth Day
From Grassroots Mobilization to Global Movement
The first Earth Day in 1970 emerged from growing concerns about industrial pollution, oil spills, and vanishing wildlife. Activists organized teach-ins that connected students, workers, and scientists.
Federal action followed quickly, with the creation of the Environmental Protection Agency and key laws on clean air and water. This environment made Earth Day a catalyst for long-term policy change.
