Protect the Earth
Dear friends，
The Earth is our home.

Protect the Earth
Dear friends，
The Earth is our home. We depend on it for everything, so we must protect it carefully.
We should do many good things for the Earth. We should reuse water and never waste it. When we go out, we can walk or take public buses to keep the air clean. We need to plant more trees to make our Earth greener, save paper and use two-sided paper. We can also make interesting toys with old cartons to reuse things.
However, there are things we mustn't do. We shouldn't cut down trees randomly, because trees are important for us. We also can't use too many plastic bags or plastic bottles, as they pollute our home.
Let's take action together to protect our beautiful Earth!
