Earth Day is an annual event on April 22 to demonstrate support for environmental protection. First held on April 22, 1970, it now includes a wide range of events coordinated globally through earthday.org (formerly Earth Day Network) including 1 billion people in more than 193 countries.

With demonstrations, town halls, legislative hearings, protests, rallies, petition drives, massive tree plantings and millions of community cleanups — through actions big and small — once again Earth Day demonstrated our power to steer the course of history, hold governments and leaders accountable and protect our world.
