The first Earth Day arose from an environmental “teach-in” organized by U.S. Senator Gaylord Nelson in 1970. The 20 million Americans who joined the demonstration signified the birth of the modern environmental movement. Every year since then, U.S. citizens have celebrated April 22 as a day to raise awareness of our impact on the world and support the protection of our environment.
This year, honor Earth Day with these free eco-friendly iPhone apps designed to celebrate our planet and support healthier, more Earth-friendly choices.
