On this day in 1970 the first Earth Day was celebrated.
Earth Day is an annual event, celebrated on April 22, on which events are held worldwide to demonstrate support for environmental protection.
It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network, and celebrated in more than 192 countries each year.
To turn Earth Day into a sustainable annual event rather than one that occurred every 10 years, Nelson and Bruce Anderson, New Hampshire’s lead organizer in 1990, formed Earth Day USA.
Building on the momentum created by thousands of community organizers around the world, Earth Day USA coordinated the next five Earth Day celebrations through 1995, including the launch of EarthDay.org. Following the 25th Anniversary in 1995, the coordination baton was handed to Earth Day Network.
