Debate for " More cars are a good thing for China."

Yesterday , Oliver takes a debate for debate.
The topic is that More cars are a good thing for china or not.

My side should demostrate for that more cars is a good thing.
But my oppnion is that more cars is a bad thing , then it was a difficult problem.

My teammembers show their oppion, and it's irradiative.
1.More cars will be index for economic improvement.
2.More cars bring us more job opportunity
3.The trip to circumjacent city or town will be more easier

Before I described my oppion , a girl in against team said that more car meant more voice and more air polution.

More cars bring us more branches of industrial design , crust design , egnine design , car seat design and so on.
There is a branch for solving the problem of more polution , so my oppion is that more cars are a good thing and are not the key problem , the key is solving the voice and air polution.

But I hadn't described my oppnion clearly for less vocabulary and a bit woozy consider,
and now , I tidy up it.
