The Earth is our home. We should protect it. But many years ago people cut down too many trees.

This made the environment bad. Smoke from cars made the air dirty. People used too much plastic. It

was bad for the Earth.

To protect the Earth, we should plant more trees. Trees help keep the air clean. We shouldn't drive

too much. We should go to school on foot or by bike. We should use cloth bags.

Let's protect our Earth and keep it clean.
