On the 22nd of April we celebrate Earth Day. It was founded by U.S. Senator Gaylord Nelson in 1970. Now this holiday is popular in more than 192 countries around the world. Earth Day is a very special day. On this day, people think about air, water to drink, food, animals and plants. Earth Day is also the time to remember that we share the Earth, our home, with millions of other plants and animals. Some people’s activities do a lot of harm to the forests. People cut down trees to build farms, homes and roads. Many animals and plants lose their homes. So the problem now is to protect life on Earth, and to save our planet for the future.
