与环境污染有关的英语作文（精选20篇）

现在的地球已经伤痕累累，这是为什么呢?原来人类向河流大批的排放污水，向空气中排放大量的废气，人们肆意的砍伐树木，浪费资源……，地球母亲怎能不伤痕累累?

我家养了几百头猪，今年快春节的时候，那些膘肥体壮快出栏的猪儿，一连死了几十头。那些天，我们全家都沉浸在悲伤之中，大家一时都慌了，不明白好好的怎么会这样?为此，爸爸特地从南昌请来了技术人员，原来是猪饮用了不符合标准的水。那么有毒的水源头在哪呢?原来是有人随意乱扔垃圾，把未用完的农药也扔在了小溪里，我家的猪正是喝了被污染了的有毒的水而死的，为此，我家损失了一大笔。如果是人喝了，后果就更可怕了。希望大家以后不要随意的乱扔垃圾，否则会有千万个像我家一样的受害者。

在我们农村，人们的环保意识比较差，人们往往随意的乱扔垃圾，就说废电池吧，大家往往用完了就随地一扔。我们的科学课上，老师曾说过废电池能破坏土壤，一块被废电池污染的土地有可能30年都恢复不了原来的样子。我们农村的人靠土地生活，如果大家都那样把用完的电池随地一扔，后果恐怕比我家那时要恐怖多了。

亲爱的同学们，为了山更绿、水更清、天更蓝，我们一起行动起来吧，我们一起手牵手，保护我们身边的环境！生活中的垃圾，请大家三思而后扔!

Throughout history man has changed his physical environment in order to

improve his way of life。 With the tools of technology he has altered many

physical features of the earth。 He has transformed woodlands and prairies into

farms and made lakes and reserviors out of rivers for irrigation purposes or

hydroelectric power。 Man has also modified the face of the earth by draining

marshes and cutting through mountains to build roads and railways。

However， mans changes to the physical environment have not always had

beneficial results。 Today， pollution of the air and water is an increasing

danger to the health of the planet。 Each day thousands of tons of gases e out of

the exhausts of motor vehicles。 Smoke from factories pollutes the air of

industrialized areas and the surrounding areas of the countryside。 The pollution

of water is equally harmful。 The whole ecological balance of the sea is being

changed and industrial wastes have already made many rivers lifeless。

Now environmental protection is more pressing than ever before。 As we know，

massive destruction of environment has brought about negative effects and even

poses a great threat to mans existence。 Indifference to these problems will

mean mitting suicide。 Therefore， effective measures should be taken and laws

passed to conserve environment。 Otherwise，man is certain to suffer from the

serious consequences caused by this lack of care for his living

surroundings。

Environmental Pollution

Write a passage with the words and phrases given:

the problem of pollution, cause, artificial substances, release, waste products, industrial production, consumption of goods, bring it under control, agriculture, chemical substancea.

Environmental Pollution

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial

production and increased consumption of goods. Bedsides, the use of chemical substances

in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

环境污染

最近我读了一则消息说在日本，许多商人向顾客出售新鲜空气，现在这种情况越演越烈，Environmental Pollution-环境污染，四六级写作《Environmental Pollution-环境污染》。为什么呢? 因为在日本新鲜空气越来越少，在美国也是如此。

事实上，环境污染是整个世界正在面临的一个严重问题。这主要是由于人造物质，工业生产过程中所产生的废料以及消费商品的增长造成的。另外，在农业中使用化学物品也造成了环境污染。看看天空，你可以看到浓烟从高大的烟囱中释放出来，这些脏而有毒的物质流入我们赖以饮水的河流，数百万吨废物正堆积在我们周围。

怎样改变这种状况呢？越来越多的国家正在试图拟定出一些有效措施控制环境污染，但至今成效不大。

[环境污染英语作文附翻译

The earth mother as the cradle of life, human like a spoiled child of the earth. She give us everything we need for life leave her, we will get nothing. Beautiful living environment is the basis of which we live, but now, our environmental protection consciousness is more and more weak. Though, we all know that protect the environment, but not the property of the consciousness of earth, destroy the originally beautiful environment; In fact, in life, as long as pay attention, everywhere can be environmental protection.

In those restaurants everywhere can see around us, the boss in order to achieve "health" standard, and unconsciously extensive use of wooden chopsticks that were made from wood; Cost is huge, hits the verdant trees with bangs fall, only the birds were forced to leave, a group of a group of lovely animals homeless again, but as they didnt see, originally natural ecological environment destroyed by them, just like that. Not only did not have the forest, and animals are not spared. Recently, some cantonese put smart cute little monkeys alive opened the brain had his head down, they looked at each cute little monkey innocent dead, but still, this is what a horrible thing!

We as the master of the earth, if you dont cherish everything now, that this beautiful environment will leave us early. At that time, we will face catastrophe, the earth will be scarred, and hurt; So we should do owners should do, well protect our survival environment, do not deliberately to destroy, remember: to protect the environment, is to protect the future of mankind.

地球母亲就像是生命的摇篮，人类就像是地球的骄子。她，给予了我们生活所需要的一切离开她，我们就一无所获。美好的生存环境是我们赖以生活的基础，可是现在，我们保护环境的意识却越来越淡薄了。虽然，大家都知道保护环境，但却不自觉的掠夺地球的财产，破坏原本美丽的环境;其实，在生活中，只要留心，处处都能环保。

在我们周围的那些餐馆中随处可以看到，老板为了达到“卫生”的标准，而不自觉的大量使用那些用树木做出的木质筷子;为此付出的代价是巨大的，一棵棵青翠的树木随着巨响而轰然倒下，一只只鸟儿被迫离开，一群又一群可爱的动物无家可归，可他们却当作没有看到，原本自然的生态环境就这样被他们破坏。不仅森林没有了，而动物也是不放过。最近，一些广东人竟然把机灵可爱的小猴子活活的把头打开把脑子吃了下去，他们看着一只只可爱的小猴子无辜的死去，却还是无动于衷，这是多么令人发指的事呀!

我们身为地球的主人，如果不珍惜现在的一切，那这美好的环境一定会早早的离开我们。到时候，我们会面临灾难，地球也会伤痕累累，而受到伤害;所以我们应该做到主人应该做的事，好好的保护我们生存的环境，不要蓄意的去破坏，要记住：保护坏境，就是保护将来的人类。

一天，小燕子飞在小河上空，远处工厂的烟囱里冒出一股股灰烟，遮着了太阳和蓝天。

漂着垃圾的小河里，小鱼探出头来，它问道：“你知道为什么河水那么脏吗?”小雨嫌弃的看着自己身边的漂浮着的垃圾。

小燕子叹了口气说：“那是人类不爱护自己的家园造成的。”

“我真羡慕你，如果这个地方受污染了你还能飞到另外一个地方，而我却只能呆在这里。”小雨无可奈何的说。

小燕子悲愤的说：“人类难道不知道是大自然抚育了他们，他们难道不应该和我们一起保护大自然吗?”小燕子越说越激动!

小鱼的情绪也波动起来，忧心忡忡的说：“地球是我们共同的家园，我们大家应该一起呵护它!

小鱼又说：“我们虽然无法改变环境，但我们可以改变自己的心情!”小鱼说完尾巴一翘就游走了。

小燕子若有所思的想着刚才小鱼说的话······

[关于环境和污染作文400字

Remember, the first day when I walk into our campus, I found the campus everywhere "care for the environment, everyone duty" signs, see the signs, I feel very happy, because I know, I live in the campus must be a beautiful environment, suitable for the place where we grow. However, the reality is very cruel and in our campus, always can see some disharmonious white trash, always can see the ground of debris-brick, I sad for it.

Today, who is destroying our campus environment, who has taken away the beauty of the campus? Everyone should know that it is us who destroy the campus environment. There are a lot of students who learn to "paint" on a clean wall. These bad behaviour, has attracted many students, however, we are always at the bottom of the moan, hardly anyone can bent down and picked up the ground of debris-brick; Few people can voluntarily erase the footprints on the wall. Is because of this, after the morning cleaning the health, in the afternoon, the campus is no longer beautiful, so today, here I take this opportunity to call for everyone: civilized and harmonious environment depends on everybody, let each of us to maintain the environment consciously, dont scribble on the wall, dont litter and pick up the waste paper.

I believe that as long as we everyone involved in protecting the environment, our campus will be bright blue sky, the wall of our campus more white, our campus will be beautiful and clean.

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive. Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. We are sure that we can have a better and cleaner place in the future.

今天,我们的自然环境质量已经成为一个重要的问题。世界人口增长如此之快,世界已变得过于拥挤。我们正在利用我们的自然资源,同时与危险化学品污染我们的环境。如果我们继续这样做,地球上的生命将无法生存。关注人在环境保护方面取得了一些进展。许多国家的政府已建立法律来保护空气,森林和海洋资源并停止环境污染。

更应该采取措施解决环境问题。人们应该进一步受过教育的认识到问题的重要性,使用现代避孕方法,来保护我们的天然资源和循环利用我们的产品。我们确信我们能在未来有更好的和更清洁的地方。

The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality. What exactly contribute to this phenomenon? Possible reasons can be listed as follows: firstly, vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and peoples living standard, urban inhabitants in mounting numbers own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally, household appliances widely used in cities also release a great mount of carbon dioxide gases, which further intensifies air pollution. Last but not least, many factories around the cities emit large quantities of untreated poisonous gases, which should also be responsible for the decline of air quality.

Definitely, air pollution will exert a detrimental impact on many aspects of peoples life. For example, many diseases such as cough, skin problem and lang cancer are caused by it. Perhaps it is high time that we should adopt some measures to solve the problem of air pollution.

此图生动地揭示了空气污染和空气质量下降的现象。到底是什么导致了这个现象?可能的理由罗列如下：首先，机动车的尾气排放是最主要的原因之一。随着经济的发展和人们生活水平的提高，越来越多的城市居民都拥有了自己的汽车，而更多地汽车势必带来大量的尾气排放。其次，城市里广泛使用的家用电器排放了大量的二氧化碳，这也进一步加剧了空气污染。最后，城市周边的很多的工厂，也每天向空气中排放大量的未经处理的有毒气体,这也导致了空气质量的下降。

With rapid development of society,the environment is becoming a more and more severe problem.Low carbon,is a new conception of the whole world.We should turned off the light when we dont use it.We can take bus instead of driving car to office.We shouldnt use plastic bag in supermaket as possible as we can.If we do that,we can have a promising future.

随着社会的快速发展，环境问题已经变得越来越严重了。低碳，是一个世界范围内的新兴概念。我们应该及时关掉不用的灯，我们应该更多的乘坐公共交通工具而不是私家车，我们在超市购物的时候不应该使用塑料袋，我们只有这样做了，我们的未来才会有希望。

我的爸爸是一个十足的钓鱼爱好者，他十分迷恋这项运动，可以称得上“酷爱”了。而我家旁边就有一条河，爸爸他经常去岸边钓鱼。

今天，爸爸的“钓鱼瘾”又发作了。这不，他正准备鱼食呢。我凑过去看爸爸将这一团一团、米棕色、散发着怪味的鱼食揉成一长条放进塑料盒子里，拿着工具去河边了。我也想去“看热闹”就搬了张小椅子跟在爸爸后面。

来到平时我并不注意的小河边，这里的场景吓了我一跳：水草布满了整个河面，隐隐约约能看见的河水已经开始发黑发臭，岸边堆积着许多垃圾，对岸还有人在往河里倒污水。我本来准备坐下的，一见这状况，连忙往后退了几步。爸爸也不敢坐得离河太近，他找了个距离河一米左右的地方坐了下来，熟练地拿出鱼竿套上鱼线和浮钩，在钩尖上放上鱼食，然后甩出去，我们便开始了耐心的等待。不一会儿浮钩开始下沉了，我们的心情随之兴奋起来。这时，老爸猛地一甩，一提，一个黑色的东西被拉出水面，爸爸迅速将鱼线绕了起来，把这个东西扯近一看：原来是一只装满果皮垃圾的黑塑料袋。我们失望地将它扔进了垃圾桶，爸爸无奈地摇了摇头。接着又钓起了一条死鱼和一只破鞋子。最后我们实在受不了这臭气熏天的气味儿了，只好扫兴而归，而河水也变得更黑更臭了......

爸爸告诉我：过去，这条河是清澈见底、鱼虾成群、水草更是少见的。大家每天都可以采到许多的水葫芦和菱角。而我们这儿产出的龙虾都是上好的，远近有名。鱼又鲜又肥，小螃蟹也有很多，如果你运气好的话还有可能捕到大螃蟹呢！可是现在这一切都成为了一个回忆，一个幻想，一个梦……这是为什么呢？答案很简单，那就是我们人类肆虐地往河里倒垃圾、倒污水。我们没有理由去推卸这个责任。

现在我真想说：适可而止吧，人类！不要再破坏我们的生存环境了，不要再残害我们已经伤痕累累的地球妈妈了！否则将来吃苦果的还是我们人类啊！

[环境污染作文：钓鱼记

“真臭,真臭!这条死水沟越来越臭了,真受不了……”几个背着书包上学的孩子捂着鼻子路过小河边.

小河听了,很委曲,看着自己那浑身漆黑,上面冒着一个个气泡,散发着让人恶心的气味,伤心地哭了,它想起了以前它是孩子们的乐园,养育着这一方水土……

以前小河的水很清,清得可以看见河底的沙石.在河边常常可以看到来挑水的人们,他们把小河的水挑回去煮饭,饮用,也用小河水来灌溉农作物.过路的人累了,渴了,掏一把水喝,都不禁赞叹：“真甜!”当气候干旱时,它更成了人们的生命线,源源不断地提供着人们的生命之水；当有台风、暴雨、洪水时,它又成了泄洪的主要通道,保护着这一方人.那是它最自豪的时候.

以前的小河很热闹.一到夏天,小河可热闹了.傍晚,这里人声鼎沸,大人在这里洗去一天的疲惫；小孩们把这当成了乐园,在这游泳戏水.那时不时传来的欢笑声、吵闹声也感染了小河,它也时不时扬起朵朵水花,和爱它的人们一起欢度美好时光,那是它最幸福的时刻.

以前的小河是这里的交通要道.那时的交通不发达,人们就用小河把自家的粮食、手工作品运到集市卖,也用小河把从集市上买来的商品运回来.每天,小河上的船只很繁忙,机器声、吆喝声、划浆声、水流声,组成一首交响曲,那是它最风光的时候.

想起往事,小河的脸上露出了慈祥、向往的笑容,要是能回到过去那多好.想到这,它收敛了笑容,沉思起来.后来人们用上了自来水,人们不再到它这挑水了.更过份的,还把垃圾倒在它这.生活垃圾、工业废水不断地侵略,小河地水越来越黑,越来越臭,河床也越来越浅,到处是垃圾.最近,在小河边建了一个垃圾堆,那恶臭的污水,流入小河,小河觉得自己和垃圾堆是“臭味相投”。

Environmental protection is everyones responsibility, we all know! But now the environment is not optimistic, such as: someone spit on the ground, someone littering, still pulling weeds, folding flowers. These are nothing, because some people, not only protect the environment, but also damage the environment. Because of the existence of this kind of person, so only in the sharp deterioration in environment, so we should protect the environment, more to damage the environment should be discouraged. In this way, the tree will be much, grass and flowers also lush, natural, such as dust storms disaster would not have happened!

Today, I let you see how should protect the environment. Some people might say, put a few piece of propaganda to protect the environment in the city brand is not good, in fact, this idea is wrong. Someone may say: this is not a propaganda to protect the environment? Of course not, because there are two reasons: 1, some people may watch brand every day, so I wont join the team to protect the environment. Will likely continue to destroy the environment and bad habits. 2, is the man looking at, but he didnt want to join the ranks to or dont want to protect the environment. From these two points can illustrate just a few propaganda brand is useless. Which someone may be eagerly asked: what! Method is very simple, as long as their faith to protect the environment, the people around will follow suit yourself!

The first step to protect the environment: learn how to protect the environment. Requirements: oneself to voluntarily protect the environment, not even in your environment, so that you even pipe request wont be able to reach others. To protect the environment the second step: advice others to protect the environment. Requirements: if see people littering or spitting, etc., should be up to dissuade immediately. Of course also want tube that yourself! To protect the environment the third step: make a collective to protect the environment. Requirement: let the dozens of people and as a collective, and protect the environment. If you do this at 3 o clock, then you are an "environmental small guards"!

This is my idea of protecting the environment. I now are trying to protect the environment, and you?

保护环境是大家的职责，大家都知道吧!但是现在的环境状况却不容乐观，比如：有人在地上吐痰，有人乱扔垃圾，还有人拔草、折花。这些都不算什么，因为还有些人，不仅不保护环境，而且还破坏环境。因为有这种人的存在，所以环境才在急剧恶化，因此我们要多加保护环境，对破坏环境的人应该劝阻。这样，树就会多了，草和花也茂盛了，自然，沙尘暴之类的灾难就不会发生了!

今天，我就让大家来看看应该怎样保护环境。有些人可能会说：在城市里放几块宣传保护环境的牌子不就好了吗，其实，这种想法是错误的。有人可能会说了：这不是在宣传保护环境吗?当然不是，因为这里有两点原因：1，有一些人有可能每天都不看牌子，所以就不会加入到保护环境的队伍中去。习惯差的，还有可能继续破坏环境。2，那个人看是看了，但他不想加入到这个行列中去或是根本就不想保护环境。从这两点可以说明光是几块宣传的牌子是没用的。哪有人可能会急切地问道：那该怎么办!办法很简单，只要自己要保护环境的信心，自己身边的人也会跟着做的!

保护环境第一步：自己学会保护环境。要求：自己要自觉地保护环境，不能连自己都在破坏环境，这样你就连管别人的要求都达不到了。保护环境第二步：劝告别人保护环境。要求：如果见别人乱扔垃圾或吐痰等，应该立即上去劝阻。当然自己也要管得知自己哟!保护环境第三步：让一个集体保护环境。要求：让几十个人并成一个集体，并保护环境。如果你这三点都做到了，那你就是一个“保护环境小卫士”了!

这就是我保护环境的观点。我现在也在努力保护环境，你呢?

Id like to tell you that our school has worked out a new program.

The purposes of the program are to make our school more beautiful, to make the air cleaner and fresher, and to turn our school into a better place for us to study and live in.

According to the program, we will plant different kinds of trees, flowers and grass in and around our school. A botanical garden will be built for us to visit and practice in. Besides, we are to build a small garden in which we can do some reading and take a rest. Whats more, some statues of famous people will be set up to encourage us to work harder. Dont you think it a wonderful program?

Welcome to our school if you have any chance.

with the improvement of our living standard, more and more people can afford a car. as a result, our roads are more often than not crammed with cars. however, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. so nowadays we advocate to lead a low-carbon life.

my suggestion is we should ride bikes more often instead of driving cars.by riding a bike, we can not only exercise our body but also protect our environment. why not have a try, my dear friends?

与我们的生活水平的提高,越来越多的人都买得起汽车的.因此,道路往往没有堆满了汽车.然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重.所以现在我们提倡过低碳的生活.

我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境.为什么不试试,我亲爱的朋友?

同学们：

你们好!

我们天都在校园里生活、学习，校园就像我们的家。每天我一走进校门，首先映入眼帘的是一片片绿油油的草坪;一颗颗高大挺拔的树木;一只只歌唱的小鸟;还有那高高耸立的教学楼，组合成了一个美丽的大花园。

虽然我们的校园是如此美丽可爱，但一些同学却不懂得珍惜，破坏环境的事时有发生。

一次，正是桂花开放的季节，风中含着桂花的清香，飘荡在校园的每一个角落。可一些同学不但不保护它，还无情地用脚踢树干，桂花纷纷从树上飘洒下来。一些桂花洒落在他头上，他一抖，桂花又飞落到地上，我去制止他，并把桂花扫进草丛中，让它们变成肥料去滋养土地。可他不但不听，反而带动了其他人一起踢，我只好无奈的摇摇头。

校园里不仅有污染环境的现象，还有许多浪费的现象。课间，有许多同学把老师放在讲台上的粉笔偷偷地拿来掰成几段，当成砸人的武器。更让人厌烦的是有人将粉笔压成粉末，夹在纸里，趁你不注意突然拍一下，那粉末就喷出来，散在空气中，让人喘不过气来。

为什么同学们会这样做呢?原因就是学生保护环境的意识太差。为了把我们的校园建设得更加美丽，为此，我提以下建议：

1.利用广播对文明行为进行表扬，号召同学们来保护环境。

2.开展保护环境、珍惜资源的活动，让同学从中知道保护环境、人人有责的道理。

3.利用黑板报等来宣传环保。

4.每年植树节时让每个同学亲手种树，品尝一下植树的辛苦。同学们，行动起来，让我们齐心协力，共创更加美丽的校园。

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。 The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

在十年前的中国，大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样，看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产，燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝，随着中国经济的迅速发展，人们生活水平的不断提高，人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题，其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬，专家们各有其立场，但对于普通百姓来说，全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖，海平面上升，冰川融化，动植物灭亡的问题，人们大多数是在电视新闻或报刊杂志上看到，恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题，人们开始关注更多的便是最近发生在北京，广州，武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康，更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象，国外专家学者很多年前便开始研究。

那么何为灰霾？灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物（PM2.5）和臭氧()、二氧化氮（）、二氧化硫（）、挥发性有机物（）等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关，还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种，直径小于2.5微米的颗粒物（PM2.5）和直径小于10微米的颗粒物（PM10）。虽然两种形式的颗粒物都对人类健康有极大的危害，PM2.5被普遍认为是更危险的，因为它的体积小，大约只有人类头发宽度的1/30。人们在呼吸时，PM2.5可以进入人类肺组织深处，甚至进入血液，造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此，PM2.5可以传播的更远，停留在空气的时间越长，影响更大的人口。PM2.5和PM10的主要来源包括机动车，电厂和其他工业源，以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合，可以在城市或农村地区天空一片阴霾，而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因，像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围，当地空气干燥，白天阳光充足。到了晚上，地表面冷却很快。地面附近的空气变冷，而上层空气都比较热，形成逆温。北京市位于华北平原的西北边缘，背靠太行山余脉和燕山山脉，面对辽阔的华北平原，东南距渤海约150公里, 地处暖温带半湿润地区，气候属于暖温带半湿润大陆性季风气候,四季分明，春季多风和沙尘，夏季炎热多雨，秋季晴朗干燥，冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远，周围地形如盆地，集热容易散热难，河湖多、晚上水汽多，城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市，而且城市海拔较低，周围至少有一面是高地，都分布在低于南北纬50度的地方。这些地区夏季阳光明媚，天气温暖干燥。在城市的盆地地区，逆温现象十分普遍。夏季的阳光使地面温度升高，城市街道和建筑物迅速升温，与炎热的物体表面接触的空气温度升高。通过对流空气向上运动，但它却不能穿透逆温层，因为上面的空气温度更暖且密度更小。空气聚集，但连续的对流形成了垂直的循环，使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下，通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集，大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响，学者称它为街谷模型。随着城市化的加速，城市及城市周边的自然生态系统逐渐被人工生态系统取代，取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续，高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时，风速迅速降低并产生特殊的湍流，使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用，因此，对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市，尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物（PM）浓度和40%的二氧化氮（NO2）浓度。因此，通过对植被的合理利用能过创造一个有效的城市污染过滤膜，对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题，相反它是一个长久的问题，从它如何形成，加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象，它只是地球环境污染的一个缩影。我们更应该探究它的根源问题，什么才是它形成的根源，什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题，但我们可以通过减少排放源，通过增加植被，加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼，越来越发达便利的交通，相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了，人们是否会怀念那晴朗的蓝天，向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

鸟，是人类的朋友;鸟，是大自然的音乐家;鸟，是自然之子。有了鸟儿，大自然更美了;没有鸟儿，世界就没有了生机。

鸟类的减少，使害虫失去控制而大量繁殖，人们被迫求助于农药来消灭害虫，这样造成恶性循环，鸟类因食物的减少而减少。为恢复和改善自然环境，我们应该植树造林。

鸟类对污染反应要比人类敏感，它的死亡与繁盛是反映环境污染程度的重要标志。城市上空黑烟笼罩、空气污浊，加上刺耳的噪声，鸟类被迫迁往他乡谋生。资料显示，由于环境因素的改变，使世界上近百中鸟类已经灭绝，还有近200种鸟类濒临灭绝的危险。可以说，严重的空气污染可造成鸟类毁灭的灾难。

我国是鸟类资源的“世界五强”之一。据统计，现有鸟类1300多种，约占世界鸟类种类的13。5%，其中候鸟500多种;鸟类多样性也极为丰富，许多珍贵鸟类为我国所特有，如珍稀鹤类8种，占60%;雉类50种，占27%;歌声婉转的画眉类334种，占24%。每年境外还有许多种类的候鸟迁徙经过我国境内。保护好鸟类资源对维护生态平衡，保护生物多样性具有十分重要的作用。可是，由于一些利欲熏心的猎鸟者盯上了它们，一些地方非法猎捕、杀害、收购、运输、出售野生鸟类案件屡屡发生。再加上一些地区砍伐树木，减少了鸟类的栖息场所。

为了共筑美好家园，请关爱鸟类，让它们与我们的心一起飞翔!

The protection of the environment is everyones responsibility!(标题)

Taking good care of our environment is very important.Wherever you live,You can do something around your neighbourhood.

its our duty to keep our environment clean and tidy.You might ask yourself,"have I picked some rubbish and thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"

If everyone makes a contribution to protectingthe environment,the world will become much more beautiful!

Dear Editor：

I am writing this letter to draw your attention to the deteriorating situation of “white pollution” in some regions despite the implementation of restrictions on the use of plastic bags.

In order to put an effective stop to the wide spread of “white pollution”， I would like to make the following suggestions . Firstly， the price of plastic bags should be further raised; Secondly ， special government departments should be established to supervise the making and using of plastic bags to ensure they are used when really needed.

I hope my suggestions would be of help and thank you for your attention.

What is my ideal? This question has been in my mind for a long time. Well, everyone will laugh and say that I just want to be a security guard.

If you dont believe me, I am a small officer who cant reach the 14 products, but if you dont believe me, please listen to me.

Our community is famous for "thieves". I used to have a very good bike, because I didnt have a lock, so I had to stop in the small village. The next day I woke up to the garage, and my car didnt even have a shadow. At first I thought my mother was riding, and then I asked, it was stolen. Another time, we were not at home, the thief even climbed into our house and stole over 500 yuan!

The madness of the thief has made it impossible for the inhabitants to live in peace, so I resolved that I must defend our community when I grow up. I promise you that I alone will never let anyone who destroys the community get away with a precious thing.

Although this position is small, but without security, our homeland will not be peaceful and harmonious.
