Every year on April 22, Earth Day marks the anniversary of the birth of the modern environmental movement in 1970. Fifty years ago Earth Day gave a voice to an emerging public consciousness about the state of our planet.
Today, Earth Day is widely recognized as the largest secular observance in the world, marked by more than a billion people every year as a day of action to change human behavior and create global, national and local policy changes.
