Cars and Earth

     Nowadays, with the living standards improving fast, masses of people own cars, which certainly

benefit them a lot. But more and more cars will give out poisonous gases and cause air pollution, which

does great harm to the environment.

     Therefore, human beings are faced with an urgent task to take measures to save the earth. The

government should pass laws and limit the number of cars. Or we may use environmentally friendly cars

to reduce the pollution.

     After all, we have only one earth. If we continue polluting it, we shall be punished in time. So, we

should make proper use of cars and protect our earth.
