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， if it’s not neccessary， we had not better travel by cars.Second， people should be encouragede to choose public transport， such as bus， bike， subway or the light rail. People can go out by them. Third， if we don’t go far away， we can choose to walk， ride bike， by bus instead of drive private cars. Choose public transport is helpful to change air pollution and travel jams. By the way， choose public transport can keep our health.

In a word， I belive that our environmen will more beautiful if we all choose green travel.

That’ all， thanks.
