Do you know Earth Day? Every year on 22 April, people all over the world celebrate Earth Day. It is a time to work to keep our Earth clean. People plan projects(项目) to clean up the land, air and water.
Gaylord Nelson from the US first thought of the idea for Earth Day in 1962 when he saw dirty rivers and cities with smoke. He needed to get support(支持) from Americans to clean up the Earth. Finally, on 22 April 1970, 20 million Americans celebrated the first Earth Day together. Now many countries around the world celebrate it, and you can too.
How can you celebrate Earth Day? Here are a few ideas:

◇Use less water.
