h for future generations. Growing out of the first Earth Day, Earth Day Network is the world’s largest recruiter to the environmental movement, working with more than 50,000 partners in 196 countries to build environmental democracy. 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. The passage of the landmark Clean Air Act, Clean Water Act, Endangered Species Act and many other groundbreaking environmental laws soon followed. Twenty years later, Earth Day went global, mobilizing 200 million people in 141 countries and lifting environmental issues onto the world stage. More than 1 billion people now participate in Earth Day activities each year, making it the largest civic observance in the world.
