汽车带来的环境污染英语作文优秀20篇

我是一条河，我非常快乐，我有很多朋友：小鱼、大树和小朋友们。

随着时光的推移，以前健壮的我，现在却这样瘦弱。以前美丽的我，现在却如此的丑陋呀!以前我整天欢快地歌唱，而现在我每天都看着天空，不断地唉声叹气。这都是因为我身上的这一大堆垃圾。我的脸上自从有了泥沙，就成了一个便利又肮脏的垃圾地。一旁的大树吸取了脏的水，还差点枯死。那天，小鱼也带着所有伙伴悄悄地离开这里。为了不让我太伤心，小鱼们在夜里行动。

那次，有两个小男孩回家路过这里，其中一个说：“我们快走，这里太臭了!”另一个人点点头。于是，他们风一样的跑远了。“你们别走啊!”我大声地喊。可是，再怎么喊也是没用的，因为谁愿意到这个“垃圾场”边玩呢?这时，我的眼睛里不禁留下了眼泪。

人类，请你们不要乱扔垃圾，这样，你不仅仅是破坏环境，还会危害地球。为了我们共同的家园，请一起保护环境吧!

你知道吗？我们周围的环境受到了严重的污染，比如前几天的阴霾天气，沙尘暴都让我们出不了门，看不到蓝天和白云。

我想如果在每年植树节的时候，每人种上一棵树，就是13亿棵树，而且分布在全国各地区，这样就会让我们的天空更蓝，大地更绿，空气更清新！

如果每人去饭店吃饭都能把剩余的饭菜打包，少点餐，实行光盘行动，那么农民伯伯的努力也不会白费了！

我们对保护环境作的太少了，以致最后结出了这样的恶果。地球妈妈需要呵护，一个人的力量是弱小的，大家的力量是强大的，让我们一起拯救地球，让地球妈妈绚丽多彩，不再黯然失色！

When it comes to harmony, you might think that this is an abstract, general concept. Its hard to see what it really is. Maybe if you read the following, it will be clear what harmony is.

It may be a definition of nature. Indeed, the weak creatures must be the belly of powerful creatures. But the ring of the ring is also a natural harmony. When a large number of frogs die, there will be a plague of locusts and food. As a result, food prices have skyrocketed and financial crises are inevitable.

A remote road in the United States, called maltin, is clogged with vehicles. The reason is to make way for the snake. Originally, the construction of this road, destroyed the "channel" of snakes. In that year, there were not only frequent incidents of snake wounding, but also in the north of Fulton, there was a crop failure, and the rats were overrun. The reason was that there were too few snakes!

The Yellow River, our mother river, the silt accumulation, this is also the result of the harmony that the Chinese people break. In the upper reaches of the Yellow River, the water is clear and transparent. But as she flows through the loess plateau, piles of sediment flow into the water, making her muddy. The loess plateau was a green place hundreds of years ago. It is because of human logging that soil erosion and silting are deposited in the Yellow River.

See, isnt this an example of a typical human being who destroys his own harmony with nature and leads to his own detriment?

But have you thought about it? Why do humans destroy the food chain? Undermine your harmony with nature? Why would humans be so desperate for natural safety?

For one thing, many people dont know enough about the food chain. Dont really understand what the food chain is! Second, and most important, human beings have endless desires. Some people, to satisfy the desire of money, killed the elephant, saw the tusks with saws, saw the ivory to buy the crafts, and got a lot of money. Of course, there are also people who pay a lot of money to buy mink, leopard skin, tiger fur coats. Because of this, there will be many people to kill and sell, like those lovely and good animals to death. Others are just to vent their anger and abuse the petite little creatures that have no resistance to human beings. Of course, there are also people for entertainment, for their own sake, and go hunting. So many cases, in fact, is mans endless desire.

But the development of mankind is precisely because human beings have endless desires. People have invented elevators, cars, trains and planes because they are too lazy to walk. Someone has invented a massage chair, air conditioner, etc. The war that led to the rapid progress of mankind is also rooted in the desire to be bullied by powerful, desirable countries. Thus, the development, creation, the establishment of its own international status. Therefore, no desire, no progress, development.

Destruction is inevitable as you develop to satisfy your desires. But if, at the same time, it also protects nature, afforesting and releasing animals, then this is a virtuous cycle. As the workers of the great hinggan mountains said, "we cut down trees, we also have trees, one hand and one hand." We should also protect our own nature.

Nature is like a very tight equation, like a long iron chain. It is always a ring and a ring. The incompleteness of the equation will affect the problem and lead to the deviation of the result. Once the chain is rusted, it disconnects, loses its ability to function, and causes significant losses at critical moments. Therefore, we humans should not deliberately destroy the harmony of nature, while destroying it, our human interests actually suffer a great loss. We need to protect nature and establish a harmonious relationship with nature.

You must have been able to understand the real harmony here.

现在的我们已进入了非凡的创新年代，当我们在享用科技带给我们都方便的时候有谁看见过我们的城市，小溪不在清澈，天空不再蔚蓝，所有的天气事物，都露出狰狞的面孔，几千年前，是大自然用甘甜的乳汁哺育了我们，可今天，它却不顾一切代价要惩罚人类的所作所为。

低碳生活，对于我们普通人来说，是一种态度和认识，而不是能力，我们应该积极提倡并去实践低碳生活，注意身边的细节，从点滴做起。

绿色出行就是采用对环境影响最小的出行方式。即节约能源、提高能效、减少污染、有益于健康的出行方式。多乘坐公交汽车、地铁等公共交通工具，合作乘车，环保驾车，或者步行、骑自行车等。只要是能降低自己出行中的能耗和污染，就叫做绿色出行。

我们所做的，已使小河不在清澈，空气不在清新，伴随着马路上汽车发动机的响声，一切美好的记忆都消失在了浓浓的灰烟里，随手丢垃圾、随地吐痰、乱扔纸屑及果壳等破坏环境的行为在生活中早已不是什么事了。但是，我们是否想过后果?公园里，我们喝完的饮料瓶、包装袋随手乱丢，那青草地旁的小河，早已在我们的共同点缀下穿上了一条色彩斑斓的花衣，

环境保护涉及每一个人的切身利益，也需要每一个人的积极参与。我们的自觉参与，是环境保护与可持续发展的重要条件。因此，需要提高我们参与环境保护工作的主动性和积极性，在日常生活中，我们应时时处处自觉地参与环境保护的各种活动。并有着强烈的环保意识，学会解决环境污染问题，变废为宝。并利用资源，从而使得人与自然和谐共处。

同学们，勿以恶小而为之，勿以善小而不为，让大自然不再为我们的行为叹息，不再让大自然为我们的一举一动哭泣，地球母亲的健康与我们的一举一动息息相关，让我们保护地球保护我们仅有的家园吧!

在21世纪的今天，人类的科学经济发展已经达到了很高的水平。然而我想问：你们有没有意识到人类的活动对环境会造成怎样的影响呢？

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失，使许多地区成为沙漠。人类的活动范围在不断减少，这不可怕吗？

人类除了破坏森林之外，难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性，目前世界上60%的地区面临供水不足，已有20%的人口难以得到清洁水，51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的，现在的工厂及我们生活中的污水，没有通过处理就排出去。这不是最好的证明吗?据研究，每排放1立方米污水，就污染14立方米天然水。想一想，这是多么可怕的数字？

在工厂排出的浓烟里，我们不知道浓烟是污染大气的吗?科学家发现，至少有100种大气污染物对环境产生极大危害，直接影响人们的健康。

难道我们想在这种环境中生活吗？当然不想；那让我们用行动来证明吧！我们可以从我做起，从现在做起，从身边做起。树立爱自然、爱护环境的意识吧！来做宣传环保的使者!让我们一起为保护环境行动起来吧。

Recently I found out that some bad things happened in our school.

At ordinary times is very neat and clean campus, has recently become some dirty, some corner or in the corridors, students can be seen the plastic bags used to hold things, eat some fruit peel, cabinet and throw away the packing bag of after loud snacks. Is each class in our school there is a certain region responsible for cleaning, clean, will arrange the students per class every day the rubbish is certainly in the classmate after cleaning the health, and others left, I think the quality of the students really is very low, I dont know to cherish other peoples work achievement, dont know how to protect the campus environment.

Students, not to be good, not to be, not to be evil small but to be, everybody join hands together, protect our campus environment together!

最近我发现我们的学校发生了一些不好的现象。

平时十分整洁干净的校园，最近却变的有些脏兮兮的，一些角落里或者是走廊里，都能看到同学们用来装事物的塑料袋，还有一些水果皮、碎纸屑和吃完小零食以后扔掉的包装袋。我们学校是每个班都有一定的卫生打扫的负责区域的，每天每班都会安排学生打扫，这些垃圾肯定都是在同学打扫完卫生之后，又有人丢下的，我觉得这些同学的素质真的很低，都不知道珍惜别人的劳动成果，不知道保护校园的环境。

同学们，不以善小而不为，不以恶小而为之，大家携起手来，共同保护我们的校园环境吧!

今天放学，我们每一个小学生都收到了一张通知。通知的题目是：“松下环境小卫士杯”浦东新区青少年“垃圾分类网上行”实践活动。

回家以后，我和妈妈一起登录了网站，注册成功后，打开网页我第一眼就看到了“垃圾分类小游戏”，我拿起鼠标点了起来，一共有22种不同的垃圾，要把他们放进不同的垃圾桶里，第一次我错了好多，因为有些垃圾，我不太清楚他们该如何分类，于是我又反复玩了几次，而且还注意看了游戏结束时，出现的分类小知识。这次我把所以的垃圾全都放到适合的垃圾桶里去了，满分，哈哈，我好高兴啊!

游戏做完了，我和妈妈一起参加了知识竞赛，里面的题目我都看不懂，妈妈一边给我读题一边给我讲解意思，还有好多妈妈也太不清楚，30题我们只做对了24题，而且时间还差点不够用了。妈妈说：“看来我们对绿色环保的知识了解得太少了，以后要多看看这方面的书籍，了解掌握了，才能成为真正的环境小卫士!”让我们一起学习吧!

Nowadays, the environmental protection is becoming one of the most important issues in the world. Being one of the members of our society, what shall we do to protect the environment

First, stop using plastic bags, boxes and bottles. Stores should be required to use the bags, boxes and bottles which are made from paper. Secondly, more and more trees and flowers should be planted to keep our surrounding clean. People must be required to plant plants around their houses and work places.

Finally, we must control the pollution by law, according to which, polluted water and air exhausted from factories should be forbidden.

These are some of the measures that we can take to protect our environment and they are not hard tasks for us. Remember, the earth is the only planet we could live at present.

Since the first day, BNBM has paid more attention to protect the environment as its social responsibility, by developing green building materials, producing green products and creating green enterprise. According to the spirit of "From the nature, for the nature and return to the mature", BNBM has tried its best in developing new technology and improving equipment to reduce the pollution.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

Do something to protect the environment

保护环境，从我做起

We want to hold a green Olympic Games ,so everyone should do something useful to protect the environment ,whether it is big or small.

我们要举办一个绿色奥运，每个人都应该做些无论是大或小的有用的事来保护环境。

We should do something to stop people from doing bad things to the environment .We should put rubbish into dustbins instead of throwing it about. Everyone must care for flowers ,grass and tress in public .We shound collect things like paper ,plastic bags our neighborhood as well ,it’s necessary to plant more trees every year .

我们应该做些什么来阻止人们对环境做一些不好的事情。我们应该把垃圾放进垃圾箱而不是直接扔了，每个人都必须爱护公共场所的花，草，树木。我们应该收集社区的一些像纸，塑料袋的东西，每年种植更多的树是必要的。

It is everyone’s duty to make our neighborhood much better with our hands minds .Let’s make a contribution to protecting the environment and the Plympic Games successfully.

用我们的双手和头脑使我们的社区变得更好是我们每一个人的职责。让我们为保护环境做贡献，祝奥运会成功。

Although the world develops much faster and better, the resources on the earth get fewer and fewer. In order to protect them,something must be done.

尽管世界发展得更快，更好，地球上的资源越来越少。为了保护它们，必须做些什么。

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.

节约用水。水是生命之源。没有水，就没有生命。所以，我们这样做是非常重要的。我们不仅要保护饮用水和停止污染，而且充分利用它。

庆幸的是,越来越多的人们已经意识到这种严重情况。许多国家已经通过了法律来阻止环境受到进一步的污染。人们正在努力想办法使地球保持清洁:他们对待废气、保护水资源和净化废水。可以肯定的是,控制人口的增加是一种最有效的方式。

然而,在未来将需要更多的努力赢得了战斗反对污染的法律控制污染,必须严格执行,而且最重要的是,在教学中应重视对人民的教育,使每个人都将显示他正在关注环保

A larger and larger part of society is expressing its concern about environmental protection. Active in their concern, teachers and students hold specific meetings to discuss environmental protection. Also, city planners take environmental problems into serious consideration. And, though reducing pollution can be expensive,

factories often take every possible measure to do their part. Many people are concerned and active because air and water pollution affects everyone and makes it difficult for cities to survive and businesses to make a profit.

一个越来越大的社会的一部分是表达他们的担忧关于环境保护的。活跃在他们所关注的,教师和学生举行特别的会议来讨论环保。同时,城市规划者们把环境问题进行认真的考虑。还有,尽管减少污染可能会很昂贵,生产厂商经常会采取一切可行的措施来履行自己的职责。许多人都关心和积极的,因为空气和水的污染影响每个人都大打折扣,使得城市生存和企业盈利。

[怎样保护环境英语作文2篇

污染？一个惹人讨厌的词。可我怎么也想不通，为什么那么多人却偏偏喜欢污染。光是我们学校的垃圾就数不胜数。

今天的班队课，老师带我们去楼下捡垃圾。

我们来到桃李芬芳景区，映入眼帘的是各种各样的垃圾。一看那满地火红的山茶花瓣、嫩叶就让人知道一定是那些低年级小朋友把山茶花和山茶叶从枝头摘下来，玩“天女散花”的游戏。地上的纸片、纸团几乎铺满了整个地面。幸好我们班人多，人多力量大，我们三下五除二就把大部分垃圾给“搞定”了。

我们路过操场时，我不免想起一件事：今天早上做操时，我的右脚踩进了一个小坑里，导致我做操时左肩高右肩低的，十分不雅。挖这个坑的人也太缺德了，操场本来就不太美观，再加上这个“坑”……

我们又来到雪松公园。雪松下面灌木丛中的“小”道已经不小了。我还记得，一年级我刚来时，这小道只有二三十厘米宽，而现在却有一米多宽了。旁边一块裸露的土地仿佛在向我哭诉：“呜呜呜……我身旁明明有一条石板铺成的小路，可很多同学不走石板路，反而在我身上跑来跑去……结果我从一片生机勃勃的草地变成现在这个样子，呜呜呜……”

学校是个大花园，是培育我们的摇篮！我们要让“大花园”更加美好，不要让它受到破坏！

World Environment Day was established by the United Nations General Assembly in 1972 to mark the opening of the Stockholm Conference on the Human Environment. Another resolution, adopted by the General Assembly the same day, led to the creation of UNEP .

World Environment Day can be celebrated in many ways, including street rallies, bicycles parades, green concerts, essay and poster competitions in schools, tree planting, recycling efforts, clean-up campaigns and much more.

Heads of State, Prime Ministers and Ministers of Environment deliver statements and commit themselves to care for the Earth. More serious pledges are made which lead to the establishment of permanent governmental structures dealing with environmental management and economic planning. This observance also provides an opportunity to sign or ratify international environmental conventions.

World Environment Day, commemorated each year on 5 June is one of the principal vehicles through which the United Nations stimulates worldwide awareness of the environment and enhances political attention and action.

The World Environment Day theme selected for 2004 is Wanted! Seas and Oceans - Dead or Alive? The theme asks that we make a choice as to how we want to treat the Earths seas and oceans. It also calls on each and every one of us to act. Do we want to keep seas and oceans healthy and alive or polluted and dead?

The main international celebrations of the World Environment Day 2004 will be held in Barcelona, Spain in close collaboration with the Universal Forum of Cultures. UNEP is honoured that the City of Barcelona, the Catalan Regional Government and the Government of Spain will be hosting this important United Nations day.

世界环境日成立于1972年由联合国大会开幕纪念斯德哥尔摩人类环境会议。另一个决议,联合国大会通过的同一天,导致联合国环境规划署的创建。

庆祝世界环境日可以在许多方面,包括街头集会,自行车游行、绿色音乐会、论文和海报比赛在学校、植树、回收工作,清理活动等等。

国家元首、总理和部长环境提供声明和承诺照顾地球。更严重的承诺是导致建立永久性政府结构处理环境管理和经济规划。这个仪式也提供了一个机会签署或批准的国际环境公约。

6月5日世界环境日,每年纪念的主要车辆通过联合国促进全球环境意识和提高政治关注和行动。

2004年世界环境日的主题选择想要的!海洋和海洋——死的还是活的?主题要求我们做出选择,我们要怎样对待地球的海洋和海洋。它还要求我们每一个人采取行动。我们想要保持海洋和海洋健康和活着的或污染和死了吗?

的主要国际庆祝世界环境日2004将在巴塞罗那举行,西班牙与环球论坛密切协作的文化。联合国环境规划署是巴塞罗那市的荣誉,西班牙的加泰罗尼亚地区政府和政府将主持这一重要的联合国日。

When winter comes, the topic of haze will never be ignored. When it comes, many pictures will be showed. People make fun of these pictures and they actually laugh at themselves, living with these poison air. Even in the daytime, people can’t see their faces beyond 10 meters. Many schools choose to stop the class and let the students stay at home. It is obvious that haze is a great threat to people’s health. This new type of destruction is the result of polluted environment. Businessmen chase for the profit and take the cost of polluting the environment. Now their offspring have to suffer from it. It is never too late to do something to protect our earth.

当冬季来临的时候，阴霾的话题永远不会被忽略。当雾霾到来的时候，人们会为它拍摄很多图片，之后再取笑这些照片。但是他们实际上嘲笑的是他们自己，因为他们生活在这些有毒的空气里。即使在白天，如果超过10米的话，人们都会看不见他人的脸。许多学校选择停课，让学生呆在家里。很明显，雾霾严重威胁到人们的健康。这种新型的破坏是环境污染的后果。商人们追求以污染环境为代价的利润，现在他们的后代都得遭受到恶果。现在为保护我们的地球付出努力还为时不晚。

We should all know that everybody is responsible for protecting the environment!

We live the earth is very fragile, the earths natural resources is limited, if we protect the environment and the earth from now on, we live the earth will become more beautiful!

Protecting environment starts from me from the us side of small start!

To protect the environment is to protect the earth or indirectly protect us humans, if the environment is destroyed, then to the survival of our homes is likely to be swallowed up by the desert!

I am here is appealing to people around the world to protect the environment is everyone duty! If we are in such environment, our home is about to be collapsed. Then we will have no place, everybody is responsible for protecting the environment, start small make up,

If we do not litter, spit, etc.

Everybody is responsible for protecting the environment!

我们大家应该都知道保护环境人人有责!

我们生活的地球是很脆弱的，地球上的自然资源也是有限的，如果我们从现在开始保护环境和地球的话，我们生活的地球一定会变的更美好!

保护环境从我做起从我们大家身边的小事做起吧!

保护环境就是保护地球还是间接的保护我们人类自己，如果环境被破坏的话，那么我们赖以生存的家园就很有可能被沙漠吞噬 !

我在这里向全世界的人们呼吁 保护环境人人有责 ! 如果我们还在这样的破坏环境的话，我们的家园即将遭到崩溃 。 那时我们便没有去处了， 保护环境人人有责 ， 从小事开始作起吧，

如我们不乱扔垃圾， 随地吐痰等。

保护环境人人有责!

一：环境污染的根源

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。

二：环境污染

就最近这几年来看，随着各地区的经济迅猛发展，环境污染问题也越来越严重，保护环境，维持生态平衡也成为了我们每个公民应尽的责任和义务，也是为了社会更好发展的一项重要举措!

何为环境?从哲学的角度来看，所谓环境，主要指我们所研究的主体周围的一切情况和条件。对于人来说，环境是指人生活于其中，并能影响人的一切外部条件的综合。人的生活离不开好的环境，在人类几百万年的历史进程中，环境对开创人类文明和进步发挥着巨大作用。

大气资源、水资源、土地资源等等，都是让人类得以生存的物质基础;而森林资源、矿藏资源等资源又为人类的不断发展提供物质，创造出地球上高度的人类文明。但是，人类在开发利用环境资源的同时，也对自己的生存环境产生了一系列环境问题。

在我们身边就有很多污染环境的污染物，例如说：大量的生活废弃品，塑料袋(也称白色垃圾)，一次性木筷，一次性饭盒，果皮纸屑。污染物对环境来说，毫无疑问，肯定有很大的危害，例如动物的腐烂的尸体会影响环境卫生，而且还会滋生细菌。饭店、餐馆认为很卫生的一次性木筷，使用后随便一扔，影响了市容，破坏了环境。。

现在像我们柳疃镇、青乡乡，最近电网部门纷纷撤除喷水机器的使用。喷水机的使用对环境的污染更加恶化、污染了水资源对人们的身体健康危害甚大。人类的活动会使大量的工业、农业和生活废弃物排入水中，使水受到污染。又例如说，我们北部渤海湾受到工业、印染厂的废弃物排放大量鱼虾死亡，地区农民上海捕鱼，鱼的体内含有大量化学物质对人们的身体健康造成了危害。据资料统计，目前，全世界每年约有4200多亿立方米的污水排入江河湖海，污染了5.5万亿立方米的淡水，这相当于全球径流总量的14%以上。1984年颁布的中华人民共和国水污染防治法中为“水污染”下了明确的定义，即水体因某种物质的介入，而导致其化学、物理、生物或者放射性等方面特征的改变，从而影响水的有效利用，危害人体健康或者破坏生态环境，造成水质恶化的现象称为水污染。水的污染有两类：一类是自然污染;另一类是人为污染。当前对水体危害较大的是人为污染。水污染可根据污染杂质的不同而主要分为化学性污染、物理性污染和生物性污染三大类。

最近，我发现政府部门、昌邑环卫局开始大力整治环境，沿街排查污染源，青乡街也定点安置了便民垃圾桶，替代了原来垃圾围绕街道，臭气熏天的状况。各个村庄开始整治村内环境的污染源，使街道、村庄焕然一新!而这不是主要的，更重要的是我们每个人自觉保护环境，保护我们赖以生存的家园，为了我们更为了我们的后代，树立好榜样，奠基好基础，让我们的家园更加美丽、更加丰富多彩!

所以呢!环境与我们的生活密切相关，保护环境卫生从我做起，从现在做起：不随地吐痰;不乱扔垃圾;废弃电池和塑料袋要处理好;多植树造林，不践踏草坪;不污染水源。保护环境，我们有责!看你的行动喽!

小建议：家庭生活中的塑料瓶可以做成装饰品，可回收物品可以卖出，换来金钱买实用的东西岂不很好?一次性木筷消毒清洗一下可以做成装饰品，你也能开小店赚大钱了!化废物为贵宝，让自己的心情更舒畅，让自己的心灵更纯洁，让自己的家庭更温馨!

三：环境污染

在二十一世纪的今天，人类赖以生存的地球环境越来越恶劣，灾难频发，旱灾、洪涝灾害、土地沙漠化、地震、全球气温上升、海啸等等过去，以我所受到的信息宣传，简单以为环境污染只是浓烟滚滚，或者水面上漂浮着垃圾、发出恶臭，蚊虫成堆、尘土飞扬等等。但是，今年从网络、报纸、广播、电视、人们的关注里，我似乎明白；现实的情况要糟得多。西南五省大旱，就是我们自己想都没有想到的原因，专家分析：因为在过去10几年中，西南从新西兰大量引进桉树速生林，为了求短期的经济利益，毫无限制的大面积种植，以用来工业造纸，从而导致物种生态环境失衡，形成地下水严重缺失。俗话说，十年树木，百年树人，可这种桉树两三年就成材，是一种巨大的抽水机和抽肥机，不断侵蚀着其他植物物种的生存空间，而当地人却沉浸在多种树就可以保护环境的僵化错误的指导思想中，不断的在往恶性循环上发展，正是这个想到想不到的原因最终导致西南几百年的大旱灾。在报纸上，我看到温总理在一片干涸开裂的耕地上，捧着一颗枯死的禾苗，只说了一句话：“痛定思痛！”云南拥有大片的原始森林，风景名胜众多，地理环境独特，自古以来就是一个山清水秀，气候宜人的好地方，可是为了种植这种桉树，大量砍伐原始森林，想象这些经过几十年甚至数百年才形成的树木，仅仅是为了去满足最快速度的造纸而被破坏，真是让人可惜，并且痛心。据说旱灾的另一个原因，就是所有的大江小河都修起了水电站。对这一点我有自己的感受，早两年湘江的水面多么宽广，可是上游修了一个水电站后，下游的水明显减少，甚至连河床都经常露出来，同时影响到了城市自来水的引水工程，我都有这些感受，那些江河里小鱼虾们感受就应该更深了。前些天报纸上又爆出地沟油事件，报纸上说地沟油是别人吃完的饭菜倒进垃圾桶后，一些黑心商人把这些进行简单的提炼加工后，不但闻不出异味，加入香精后吃起来还挺香，但是对人体危害很大，我现在都不敢随便在外面吃东西了。环境污染的问题日益严重，影响到了我们生活的方方面面，对此我感到非常的忧虑。

四：河道为什么会污染

在我们学校旁边，有一条小河，听长辈们说，原来这里的河水清澈见底，河里鱼虾成群，夏天人们喜欢在水里游泳，还直接取水饮用呢！可如今，河水不但变得混浊，有时还有臭味呢！

为什么河水会发生翻天覆地的变化呢？经过我们全班同学的观察分析，河水污染有许多原因 。首先，人们不重视环保，乱倒垃圾。如有一次，我去张微家去玩，吃了一根香蕉，问她的妈妈：“阿姨，香蕉皮扔哪里？”只见她从我手中拿过香蕉皮，又随手用力一扔，扔进了小河，说：“这就是我们家的垃圾桶。”甚至有人把死猫死狗也扔进去了，这时，如果你从旁边经过，一阵阵臭味就会扑鼻而来。我真是不明白，人们为什么不多走几步把垃圾扔到垃圾箱里让垃圾车运走呢？。其次，人们家里的化粪池的排污口就直接通向小河。特别是我们学校，大小便没有经过处理就流进了小河，让人看了真是恶心。河水不变臭才怪呢！还有人们给庄稼喷了农药后，就在河里洗药筒等等。由于各种原因使河水变得越来越脏，甚至发臭，更不用说饮用，就连小鱼也快要无家可归了。

我想向人们呼吁：“水是生命的源泉，没有水就没有生命，就没有我们这个美丽可爱的家园，所以请你们不要再伤害小河了，难道你们就没有看见小河在哭泣吗？”

It was the industrial revolution that gave birth to environmental pollution as we know it today. The emergence of great factories and consumption of immense quantities of coal and other fossil fuels gave rise to unprecedented air pollution and the large volume of industrial chemical discharges added to the growing load of untreated human waste. Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in 1881. Other cities followed around the country until early in the 20th century, when the short lived Office of Air Pollution was created under the Department of the Interior. Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late 1940s, serving as another public reminder.

In the forest, groups of trees, flowers in full bloom. W as usual, settled on a tree east peck peck, peck peck, in an effort to save the tree.

Suddenly, it saw an intruder -- a lumberjack, and was holding a pair of wood chopper in cut down a tree, and idly smoking a cigarette. "Snapping" 1, cigarette butts havent put out was he ruthlessly fell to the ground. Didnt he dont know, put out the cigarette may cause a fire? Look at he was staring, eyes shining appearance, saw a lot of money coming toward him must!!!! Woodpecker angry thought, immediately raised a nameless fire! Woodpeckers flew to quickly the woodcutters back, with a sharp mouth pecked his head. Peck, thought: it seems like locust tree grandpa is not wrong, the human mind there really is "greed" worm! Otherwise, why cut down a tree? Why and destruction of resources, do damage to the environment? Simply, do good deeds, to this piece of wood therapy!!!! The lumberjack the woodpecker attacks, at that time have no reaction to come over, paused was holding his head thrown off wood chopper ran quickly!

Through the cartoon, revealed the endless greed and lust. Through this cartoon satire of the human, telling people to cherish resources, protecting the environment! Yes! Hugo once said, let the wind no longer abroad and in the earth a green ground! Human destroy the natural environment, have also been punished, sandstorm, mud-rock flow, drought, floods and other countless natural disaster. Caused countless people sacrifice, is a human deserving.

With joy dance steps, stop sand, make the birds dance, make the green!

森林里，树木成群，百花盛开。啄木鸟像往常一样，停在一棵树上东啄啄，西啄啄，在给大树治病。

突然，它看见一位不速之客——一位伐木工人，正拿着一把柴刀在砍树，一边还悠闲地抽着烟。“啪嗒”一声，烟头还没熄灭就被他无情地摔到了地上。难道他不知道，没熄灭的烟头会引起火灾吗?看着他目不转睛，两眼放光的样子，一定看见了许多钞票朝他飞来了吧!啄木鸟气愤的暗想道，顿时升起了一股无名之火!啄木鸟飞快地飞到那个伐木工人的背上，用尖尖的嘴巴啄他的脑袋。一边啄，一边暗想：看来槐树爷爷的话真没有错，人类的脑子里真的有“贪婪虫”!要不然，干嘛砍树呢?干嘛破坏资源，干嘛破坏环境呢?干脆，做做善事，给这段木头治治病吧!那位伐木工人突遭啄木鸟袭击，一时没反应过来，愣了一下便飞快地扔下柴刀捂着脑袋就跑了!

透过这幅漫画，透露出了人的无穷无尽的贪婪和欲望。借着这幅漫画讽刺了人类，告诫人们要珍惜资源，保护环境!是的!雨果曾经说过，让风沙不再猖狂，换地球一片绿色铺垫!人类破坏了自然环境，也受到了应有的惩罚，沙尘暴，泥石流，干旱，洪水泛滥等数不清的自然灾难接踵而来。造成了无数人的牺牲，是人类应受的。

带着欢乐舞步，让风沙停止，让小鸟起舞，让绿色腾飞吧!

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!

Pollution around us

In recent years our life is becoming better and better. But our environment is becoming worse and worse. Its very bad for our life. Now many people have air-conditioners and cars, they produce (give off ) waste gas. More and more trees are being cut down. There are so much sand on the earth (leaving only sand ) . We often see factories pour waste into rivers or lakes. Water in the river is quite dirty. We havent enough clean water to drink in cities. Now we are in danger. Its very necessary and important to protect the environment well. I think if everyone tries his best to protect the environment, the world will become much more beautiful , and our life will be better and better .

我们周围的污染

近年来我们的生活越来越好。但是，我们的环境越来越糟。它对我们的生活很糟糕。现在很多人都有空调和汽车，他们生产的（出）废气。越来越多的树被砍伐。有那么多的沙子在地球（只留下沙）。我们经常看到工厂把废水倒入河流或湖泊。河里的水很脏。我们没有足够的干净的水的城市。现在我们有危险。这是非常必要和重要的保护好环境。我想，如果每个人都尽自己最大的努力去保护环境，世界将变得更加美丽，我们的生活会越来越好。

Its Our Duty To Protect Our Environment

Its our duty to protect our environment.Where do we live?The earth.The earth is the only one place we live in.So you know how important the environment is.

But now,some people are harming the environment,like cutting down trees,drawing pictures on public walls,littering onto the ground.Its terrible if we still do it.

Now,its time for all the people in the society to protect the environment.Its our duty.It needs each of us to make a contribution to improving the environment.We should make our environment more and more beautiful.
