New car problem
Nowadays more and more families own their private cars.Most people would find it hard to think what life could look like without a car.Although cars have led us to a better life,they have also brought us many new problems.
Cars produce wasted gases and smokes,which pollute air seriously.The polluted air becomes poisonous and dangerous to our health.With the increasing development of cars,cities are becoming more and more crowded.There is not enough room for cars to be parked.Worse still,more traffic accidents happen in big cities,even in the countryside.
More cars need more gas.Energy resource will run out one day if more gas is needed.At the same time,some old and damaged cars are thrown away as rubbish.That will cause another new pollution.
