Everyone can help our planet. Let's be Earth helpers!
Here are some easy ways to start: Save water and electricity. Don't let the water run when you brush your teeth. Turn off the lights when you leave(离开) a room. Plant a small tree or flowers. Plants make the air clean and nice. Walk or ride a bike to school if you can. It's healthy and it makes less dirty air. Use both sides of paper. Don't waste it—every piece is useful! Finish the food on your plate. Don't waste any food. Reuse things in new ways. An old jar can become a "pencil box". An old T-shirt can be a cloth for cleaning. Recycle bottles, cans and paper. Put them in the right bins. They can become new things like bikes or books!
