There are some easy things you can do to protect the environment and the earth. Choose ideas from the list or come up with a few of your own.

·Plant flowers, grass or trees.

·Whenever you visit a park or beach, take away what you bring there—keep rubbish in a bag until you can put it in a dustbin.

·Turn off the lights and TV sets when you leave the room. This can save a lot of electricity.

·Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.

·Keep the doors and windows closed in winter to keep warm air in.

·Give your old books and magazines to a library instead of throwing them away.

·Give your old clothes to poor children you know instead of throwing them away.

·Use both sides of paper.
