As is clearly shown in the chart that chinese possess around 200 millions cars in 1996s.Two years ago,424 millions cars possessed by chinese.In 1999s,about 625 millions cars bought in china.until 2006s,over 1407 millions cars possessed by chinese.
As the society developed,life quality improved,more and more cars bought.From my point of view,I think cars are very convenienct,but cars also give off waste gases,which are polluting the air.morever,more and more trees are cut without being planted.all in all,we also should protect environment.
