EARTH DAY NETWORK
The first Earth Day on April 22, 1970 activated 20 million Americans from all walks of life and is widely credited with launching the modern environmental movement. Growing out of the first Earth Day, Earth Day Network (EDN) works year round with tens of thousands of partners in 192 countries to broaden, diversify and mobilize the environmental movement. More than 1 billion people now participate in Earth Day activities each year, making it the largest civic observance in the world.
