Earth Day is also the time to remember that we share the Earth, our home, with millions of other plants and animals.

And because so many people care about

nature and the environment, they gather to DO things.

Do you know that there are two Earth Days?

The United Nations celebrates Earth Day each year around March 20 when spring officially arrives.  This tradition was founded by peace activist John McConnell in 1969.

The second Earth Day is celebrated on April 22. It was founded by U.S. Senator Gaylord Nelson in 1970. Now this holiday is popular in many countries of the world.
