空气污染的作文6篇

空气污染的作文篇1

air pollution is one of the major problems of the modern world. a great deal of energy is needed to run the factories of modern industrial nations. automobile, trains, planes and busses need energy, too.

nearly all of this energy is produced by burning fuels. the burning produces wastes, some of which remain in the air, causing air pollution. scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. they are studying new ways of generating electricity that may be less damaging to the environment. in the meantime, many power plants are being

modernized to give off less polluted material. also, engineers try to design and locate new power plants to do minimum damage to the environment.

however, it may be that we still have a long way to go before we have a "clean" world. nearly all of the countries are trying hard to prevent and control air pollution.

there indeed seems to be no end to tasks that environmentalists will be required to do. people will continually find new ways to control pollution.

空气污染的作文篇3

每个人都有自己的梦想。有人梦想当一名灵魂的工程师教育启发学生,有人梦想当一名钢琴师,在大舞台上演奏美妙绝伦的乐曲。有人梦想当一名科学家为社会做出对社会的贡献。而我梦想只想当一名保护环境的宣传者和执行者。“保护环境”大家并不陌生,但世界上有几人真正的做到了保护环境。小时候保护环境就成了我的最大理想。我认为保护环境要做到2点。

1、保护森林和绿色植被。森林对我们来说是不可或缺的。它像一把“绿色的大伞”,为我们这遮风挡雨;为我们过滤空气。全球每年要砍伐1100万公顷森林,每分钟有21公顷森林消失,这个数字是多么惊人!人类失去了这把伞,那我们赖以生存的美好世界就会变成沙漠:死气沉沉,失去生机,人类也将不存在了。

2、节能减排,使用清洁和可在生能源。前一段时间北京不断出现雾霾天气,pm2。5严重超标,工业废气和汽车尾气是主要原因。全球2012年用了70亿吨煤,其中百分之五十一都是中国用的,如果在这样下去没多久所以物资都会被用光的。另外,工业污水和生活污水的排放污染了江河和土地。

环境被破坏了,导致许多动植物正在不断的灭绝,没想到连凶猛的老虎也将面临灭绝。很难想像人类对大自然的破坏有多大!

我多么希望看到可爱的大熊猫在悠然的吃着竹子;凶猛的老虎在丛林中惬意的休息;长江江豚在长江中自由的嬉戏;丹顶鹤在空中无忧无虑地飞翔;扬子鳄在大江里游泳。

保护环境从我做起,从节约每一滴水和每一度电做起。让我们共同努力,一起谱写人与自然和谐相处的新篇章。让我们的祖国山清水秀、绿树成荫。让我们抬头就能看见蓝天白云;让我们呼吸的空气更加清新!

空气污染的作文篇4

too many cars have created a lot of serious problems in our world. besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. all the time, they are pumping huge amounts of waste gases into the atmosphere. these gases are very harmful, causing disease and even death. one possible solution is to design and develop clean cars and clean fuels. in shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. but it may take decades for the new models of clean cars completely replace the traditional ones. another solution is to develop modern public transportation systems and restrict the use of private cars. if the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. and the total number of cars in big cities will reduce greatly. on the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

空气污染的作文篇5

the picture reflects the air pollution is threats our healthy day by day,everybody has to wear masks to protect themselves from the fog and haze. therefore,we can not neglect the seriousness of air pollution.

as a matter of fact,we have many methods to avoid or reduce the harm of air pollution.on the one hand,the major and largest sources of air pollution come from industrial pollution and automobile exhaust.therefore,we should try to develop new energy to replace the tradition ones;in addition,public transportation vehicles is our top choice when we go out to doing something.on the other hand,we should plant more trees to absorb more carbon dioxide in the air and let trees release more oxygen through the process of photosynthesis.

in brief,the air belongs to us all and everybody on the planet ,to should take the responsibility for protecting the environment,to be specific,the air.

空气污染的作文篇6

现在,家乡的环境已经很糟糕了,可那些没有道德的人却还在破坏着环境。

家乡的水变得混浊了;家乡的土地变得贫瘠了;家乡的天变得灰蒙蒙;家乡的花草树木,却寥寥无几。这些都会影响到我们的正常生活。会给大气带来污染。既然,我们保护环境,保护大气就可以创造美好生活。我们何乐而不为呢?

我们务必做到以下几点:

1、减少污染物排放量。改革能源结构,多采用无污染能源(如太阳能、风能、水力发电)和低污染能源(如天然气),对燃料进行预处理(如烧煤前先进行脱硫),改进燃烧技术等均可减少排污量。另外,在污染物未进入大气之前,使用除尘消烟技术、冷凝技术、液体吸收技术、回收处理技术等消除废气中的部分污染物,可减少进入大气的污染物数量。

2、控制排放和充分利用大气自净能力。气象条件不同,大气对污染物的容量便不同,排入同样数量的污染物,造成的污染物浓度便不同。对于风力大、通风好、湍流盛、对流强的地区和时段,大气扩散稀释能力强,可接受较多厂矿企业活动。逆温的地区和时段,大气扩散稀释能力弱,便不能接受较多的污染物,否则会造成严重大气污染。因此应对不同地区、不同时段进行排放量的有效控制。

3、绿化造林,使有更多植物吸收污染物,减轻大气污染程度。

只要我们坚持保护,努力创造。我相信,我们家园一定会更美好,阳光将会更灿烂!
