The increase of private cars has brought more and more serious air pollution and traffic jams in our city, especially in the rush hour.

So I think it’s time to promote the green travel at present. In my opinion, first, we’d better not travel by car unless it’s necessary. Second, people should be encouraged to choose the public transport. They can take a bus or the light rail. They can even go by underground. These ways of travel can save energy and reduce air pollution .They can also improve the traffic conditi. Third, we should choose to walk or ride a bicycle if we don’t go far away. Travelling on foot or by bike provide us with a chance to make us stronger and healthier.

In a word , I believe that we can improve the environment as well as our traffic conditi if we all choose the green travel.
