Earth Day

In 1970 smog choked major U.S. cities and toxic waste flooded rivers. That same year nearly 20 million Americans participated in events on April 22, spearheaded by Wisconsin Senator Gaylord Nelson, to draw attention to the environmental issues plaguing the planet and human health. Named Earth Day, April 22 has remained a time to celebrate restoration and stand up for the planet.
