高中保护环境的议论文如何写？( 六 )

赤潮虽然自古就有，但随着工农业生产的迅速发展，水体污染日益加重，赤潮也日趋严重。我国自1933年首次报道以来，至1994年共有194次较大规模的赤潮，其中60年代以前只有4次，1990年后则有157起。石油类污染对水质和水生生物有相当大的危害。漂浮在水面上的油类可迅速扩散，形成油膜，阻碍水面与空气接触，使水中溶解氧减少。油类含有多环芳烃致癌物质，可经水生生物富集后危害人体健康。二氧化硫主要由燃煤及燃料油等含硫物质燃烧产生，其次是来自自然界，如火山爆发、森林起火等产生。二氧化硫对人体的结膜和上呼吸道粘膜有强烈刺激性，可损伤呼吸器管可致支气管炎、肺炎，甚至肺水肿呼吸麻痹。短期接触二氧化硫浓度为0.5毫克/立方米空气的老年或慢性病人死亡率增高，浓度高于0.25毫克/立方米，可使呼吸道疾病患者病情恶化。长期接触浓度为0.1毫克/立方米空气的人群呼吸系统病症增加。另外，二氧化硫对金属材料、房屋建筑、棉纺化纤织品、皮革纸张等制品容易引起腐蚀，剥落、褪色而损坏。还可使植物叶片变黄甚至枯死。
保护环境，人人有责。

高中保护环境的议论文如何写？

【高中保护环境的议论文如何写？】My Views on Environmetal Protection Nowadays, the world we live in is becoming more and more intolerable because of environmental destruction.Each day thousands of tons of gases come out of the exhausts of motor vehicles.Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside.Recently,haze weather has become a usual phenomenon here in large part of China.People are forced to wear the mask to avoid breathing poisonous air.Some people think it is impoible to solve the problem,however,from my opinion,if we find out the reason and take effective measures the environment can be better.If we trace the cause for haze weather,the main points are as follows,first,our country\\'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 more likely to emit a great deal of wasted air.Third,acro our society,the awarene of protecting the environment has not built up so that people haven\\'t formed a habit of using green product and saving energy as much as poible.If we don\\'t take action to show respect to the environment, we will have to face an increasingly awful situation.Therefore, effective measures should be taken and laws paed to conserve the environment.In my opinion, to protect the environment, the government must take even more concrete measures.First, people should be educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products.Second, much more efforts should be made to put the policy of population into practice, because more people mean more pollution.Finally,laws concerning environmental protection should be put into effect and enforce strictly just as our government has been doing.To sum up,if we work together to take out such measures,our environment will get better and better and haze weather will vanish completely.
