As we all know, the earth is the place where we live, it is also our home. But, our home has been polluted now. So, we should protect the earth. But, how? To face this question, I have the following three suggestions:
First, we shouldn't throw rubbish on the floor. If each person in China throws piece of rubbish on the floor, then there’ll be 13 billion pieces of rubbish on the floor one day.
Second, when the car isn't driving, we shouldn't keep the engine running. Because if we keep on the engine running, we won't have fresh air to breathe.
The third, we shouldn't always drive our own cars, we should take public transport instead. If everyone drives their cars to work, the cars will emit too much exhaust gas.
These are the suggestions I want to give.To protect the earth we should protect the environment.
So everybody, the earth is the only home that we have. If we don't protect it, we won't have a nice place to live in!
