Recently，haze weather has become a daily one right here in large part of China.People are forced to wear the mask to avoid breathing poisonous air.So it is necessary to find out the reason why leads to that and work out the resolution.If we trace the cause for haze weather ，the main points are as follows.
First，china 's air quality standards are rather lax and evaluation factors are limited，so you will see that current air appraisal system has defects.Second，some people just go for economic interests instead of turning out products according to relevant law and regulations.They tend to use obsolete equipment in which they are high likely to emit a great deal of wasted air.Third，across our society ，relevant protection awareness has not built up so that people havent formed a habit of using green product and saving energy as much as possible.Just for the sake of convience to go out，people rely more and more on travelling and working by car while car is the main cause for the haze weather.
To settle this problem，a series of meaures should be taken as follows.First ，we should strengthen air monitor to lower the levels of small particulate pollutants.Second，we should enact more strict laws and regulations and keep perfecting our current law on environmental protection to regulate people 's daily action and the industrial production and punish those factories that ignore the protection and keep emitting dangerous material that cause haze. Third，we should develop green and energy-saving energy to lower the emission of haze and improve air quality.As far as i am concerned ，if we work together to be able to do such measures ，our environment will getting better and better and haze weather will vanish completely.
Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.
Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.
Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.
In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day.
