Air Pollution
Although china industy develop fast,it can bring a lot of profit,it can make people's life much better,But we must know it can bring some negative effect ,because everything in the world has two sides,it no exception,I think the biggese effect is air pollution.
with the many and many factories is building in city,That means it will result in city air pollution turn more andmore worse,some news have reported that many cities have polluted,It is serious that local goverment have not recogized the importanceof the air pollution,at present,some people have been hurt by the air pollution,such as have a cold,lung cancer and so on.
now,how to solve the problem of air pollution?From my perspective,firstly,I think factory must install equipmentand use technology to filter air,so that reduce air pollution,secondly,we must have conscious about the air pollution and better environment,we don not wait the air have turned more and more worse later and take some measure to protect it,I think it is behind time.
In order to our good future,we must protect environment and never give up!
