Origins of Earth Day
Earth Day was first observed on April 22, 1970, when millions of Americans joined demonstrations against pollution and environmental damage. The event was inspired by growing public concern over oil spills, smog, and toxic waste, and it helped catalyze the modern environmental movement.
