History and origins of Earth Day

The first Earth Day was held on April 22, 1970, when an estimated 20 million Americans took to the streets to protest environmental degradation. The event was spearheaded by US Senator Gaylord Nelson, who envisioned a national teach-in on the environment, with activist Denis Hayes coordinating it. Its success helped lead to the creation of the US Environmental Protection Agency and landmark laws. Earth Day went global in 1990, mobilizing 200 million people in 141 countries, and it has grown every year since.
