Every year on April 22, Earth Day is celebrated all over the world. It's a time to work toward keeping our earth clean. People plan projects to clean up the land, air and water.
U.S. Senator Gaylord Nelson first thought of the idea for Earth Day in 1962. He was concerned when he saw polluted rivers and cities covered in smog. Senator Nelson needed to get support from Americans to clean up the earth. Finally, on April 22, 1970, 20 million Americans calebrated the first Earth Day! Now many countries around the world celebrated it, and so can you.
How can you celebrate Earth Day? Here are a few ideas:
=> Join a clean-up project - clean up your street or a favorite beach.
=> Save energy - Turn out the lights when you leave a room, use less air conditioning, and use public transportation.
=> Use less water
=> Reduce/Reuse/Recycle - practice the three R's: First, reduce how much you can use. Then reuse or recycle what you can.
You can make a difference on Earth Day and every day!
