Earth Day was founded on April 22, 1970. It wasn’t until 20 years later that Earth Day went global. It is now observed by nearly 200 countries and has over one billion participants each year.
The Earth Day Network has brought to light environmental issues around the world. It has been acknowledged as a catalyst for many important laws such as the Clean Air Act, Clean Water Act, Endangered Species Act, as well as others.
A March for Science will take place this Earth Day, April 22, 2017 in Washington, D.C., with satellite marches in 425 other locations around the globe. Other Earth Day activities include Earth Day United in Copenhagen, Denmark; Earth Expo in Johannesburg, South Africa; Earth Day Tokyo; Empower Earth Day Celebration in London, and several other parades and celebrations throughout the world.
