写地区环境污染的作文1

那惨痛的一幕时时出现在我的脑海里。

5月3日，我早早地吃过了饭，沿着不老河岸边的一条小路向学校走去，忽然我听到河坡上传来哭喊声，怎么回事?我加快脚步，向前跑去。

哭喊声是从宦立才的鱼塘边传来的。鱼塘四周已经围了很多人，等我赶到那里，立刻被眼前的景象惊呆了：塘水非常浑浊，发出刺鼻的酸臭味，白花花的鱼儿覆盖在水面。还有些没死的，也在垂死挣扎，仿佛要逃脱这使它们无法生存的苦海。宦立才一家老小7口人围着鱼塘转来转去，显得手足无措，只是声嘶力竭地向人们哭诉着：“我们一家老少，起早贪黑，用了两年时间，花了近万元钱才在这不老河边上，建了这个鱼塘，今年又求亲拜友借了8千多元钱，买了鱼苗放了进去，本指望能得到好收成，年底就可以见利了没想到，没想到啊性鱼才放进一个多月就发生了这样的事，这下全完了，以后的日子，我们可怎么过啊!”

看着他们一家人那悲痛欲绝的样子，我真想上前去安慰几句，但又不知说什么好，只好也跟着抹泪。这惨相是什么原因造成的呢?听大人们说这是由于水质被污染引起的。

原来，随着经济建设的发展，不老河两岸建起了许多工厂，如化工厂、造纸厂、柠檬酸厂等，这些工厂没有污水处理设备，排放出来的“毒汁”源源不断地输人了不老河的“血管”，造成了严重的污染，危害了两岸人民的身体健康，以致发生了上面的惨相。

“污染”这个可怕的字眼，在自然课上，常听到老师讲到，然而，我没想到，它会给人们造成如此的危害，听说还有比这更严重的呢!虽然，时隔多日，但那惨痛的一幕，我始终不能忘记，我真希望以后永远不再发生这样的事情。

一天下午，太阳正高高地照在大地上。突然，旁边的工厂里排出了一阵阵废气，把太阳给遮住了。原来，工厂里正在烧一些塑料袋……天渐渐变得非常暗，乌烟瘴气的。

两只小燕子从北方飞来，听说南方很美，于是想过去看看美景。

到了南方，呀!真是美丽，可仔细一看，有几座工厂正在排放废气，于是它们到最近的工厂去看看。小燕子们飞到了一个小池塘边，有一只燕子闻到了一股臭味，心想：这里真不卫生。它想拉着另一只燕子飞回去，另一只小燕子非常善良，不肯走。

于是它亲切地问池塘中的小鱼：“你好，小鱼，你为什么在污水中生活呢?”小鱼叹了口气说：“哎，还不是那些可恶的人类，把干净的河水给污染了。”小燕子又问：“那些垃圾是从哪儿来的呀?”小鱼生气地说：“那些经过这里的人，把饮料瓶和废纸到处乱扔。”

说着说着，小鱼就死了，小燕子飞走了。今天之旅，让它们知道了乱扔垃圾乱排废气的害处，使它们印象深刻，它们以后再也不想到这样的地方来了。

写地区环境污染的作文3

汽车在高速公路上飞驰着，忽然，开始下起了雨。

起初，只是淅淅沥沥小雨，接着越下越大，很快，路上的积水越来越多，飞驰而过的汽车，尾部都拉出了一条长长的水雾，仿佛丝带一般，车窗上，星星点点的水滴好像美丽的星空，看着这诗一样的景象，我盼望着早点能到家。

但是，四周的车越来越多，没过一会就堵车了，这可把我急坏了，时间在一分一秒的流逝，但长长的车龙依旧是动都没动，我摇下车窗想要呼吸一下新鲜的空气，可谁知喧嚣的喇叭声伴随着带有汽油味和牲畜特有的臭味的空气向我袭来，我忽然感觉是如此的压抑，似乎一切都像天空那么灰暗，我回想起了以前的雨天，空气清新，令人心旷神怡，偶尔还会有太阳雨，多么的迷人，我又想起了最近炒得沸沸扬扬的霾，还有PM2。

5这些字眼在之前，从没有被人们所知晓，不是因为科学技术发达，能检测出空气中这些细小的颗粒物，而是因为之前并没有太多这样的污染物，科技的发达带给我们的到底是进步还是退步，只是几十辆汽车就能把雨后的空气污染成这个样子，那么将来的空气还能被雨所清洁吗?

真不知道，还有几场雨能像以前一样。

我的家乡以前山清水秀，鸟语花香。但人们为了种植茶叶，把大树一棵地砍了下来，导致了多次干旱和无雨。刚把茶叶种下去，就出现了很多不知名的害虫横行霸道地吃茶叶，人们忍无可忍，加重了农药喷射，使茶叶上有了很多致命的病毒。再看看家门口的小溪，以前鱼虾遍地，可现在垃圾往溪里扔，污染了溪水。鱼虾们死的死，伤的伤，最后连一只鱼、一只虾都无影无踪了。溪水已经变得浑浊不堪，黑乎乎的，散出一阵难闻的恶臭，想到人们以前在水里游泳、洗菜，可现在人们只要经过小溪，就就会不约而同的捂住鼻子，快速离开小溪边。

现在，人们已经意识到了周围的环境了，人民政府通过电视和广播告诉人们不要使用一次性筷子、不要使用塑料垃圾袋、包装袋，还启用了一种奖罚活动，栽一颗大树奖十元，砍一棵大树罚十元。还告诉人们不要破坏大自然，否则会遭到大自然的报复等。人们下定决心不再破坏环境了，还要保护环境。

在短短几年内。小溪变得干净、清澈，清得能看见最底下的石头和石上下的小鱼和小虾，山上的树木郁郁葱葱，小鸟蹦蹦跳跳地在枝头唱歌，害虫也不来我们这歇脚了，他们似乎明白这里不再是他们的天下了，家乡的草绿油油的，上面开着五颜六色的小野花，从远处看，他就像一块绣着花纹的地毯。

人们笑了，大自然也笑了，他们笑得真开心啊……

[家乡环境污染作文300字左右

air pollution comes from factories, power stations and cars. chemicals in the smoke from power stations cause a lot of damage. they can travel hundreds of miles in the wind before falling to the ground in the rain. but this "chemical rain" gradually destroys trees in the forests and kills fish in the lakes. in germany, over 50% of the country’s trees had been damaged by the year 1986.

time and time again there are serious accidents that pollute the air. in 1986 there was a bad accident at a nuclear power station in russia. a cloud of radiation crossed the whole of europe. it is said that 125,000 people died in russia as a result of illnesses caused by this accident.

in 1984 there was a serious accident at a factory in india and a cloud of dangerous gas covered the town of bhopal. over 2,500 people were killed that night, and hundreds of thousands of people were injured. many of the injured lost their sight.

人类在生产生活的过程中，每天都要产生大量的废弃物、垃圾和排泄物。这些物质若果得不到有效处理，就排放出来，就会造成环境污染。

人们产生大量的废弃物、垃圾和排泄物进入大气，就会形成大气污染，尘埃降低能见度，影响生产，还会造成人类呼吸系统疾病;进入河流湖泊，就会造成水质恶化，破坏水生生态，影响工厂、城市、居民用水;进入土壤，破坏耕地，污染物还会通过植物生长积累毒性，最终影响人类健康。

环境污染弄脏了我们的大气和水，破坏了大地，损害了我们的健康。我们应该防止和治理环境污染。

With the development of our society， energy in the world bees more and more

limited， so it is quite important for us to save energy and to protect our

environment。 As a student， there are a lot of methods we can do to save energy

at home。 For example， first， we can turn off the light as well as other

appliances when we are not using them。 Second， recycle the waste water， paper

and other waste so that we can reuse them。 Whats more， it is suggested to use

public transportation more instead of private cars.

Above all， everyone can make a great contribution to our environment。 I

hope I can learn more to develop new and clear energy， like energy from the wind

and solar.

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！

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

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

In my hometown, the air is polluted seriously. However, in recent years,

the pollution gets from bad to worse, because of the increasing number of

private cars. Especially during the rush hours, too many private vehicles move

slowly on narrow roads, emitting a large amount of waste gas. Moreover, the

poisonous gas sent by the nearby factories is also one of the main causes of

pollution. Therefore, it’s demanded that immediate and effective measures must

be taken to restrict private cars and public transportation must be developed to

the largest extent. Besides, we should use renewable and clean energy

recourses.

我们的家乡现在是多麽美丽，绿色的草坪，五颜六色的小花，公路上那么长的绿化带。看到这美丽的景色，谁能想到我们的家乡原来的模样啊!

原来，我们的家乡遍地的垃圾，说不定你走到哪里，脚下踩的就是别人吃完随手扔的垃圾。绿色植物很少很少，简直少得可怜，这与“森林王国”奥地利相比起来真是天壤之别。而且，如果你走在路上，从身后开过一辆车，绝对能荡你一身尘土。路边的小花小草身上也全是灰尘。

而现在，放眼一望，很少再看见垃圾袋了。绿色植物哪里都有，虽然比不上奥地利的那么多，但也比原来好多了，而且，在我们学校附近，还有许多个小花园，里面种着许多小花大树。走在路上，觉得空气新鲜。

我幻想在未来，出门就是草地，抬头就是大树。站在屋顶上那个远眺，到处是绿色，树木成片成片，每一棵树都是绿色的浪花，每一片树木都是一片海洋。再也看不到垃圾。这样的话，我们也就生活在层层叠叠的绿色之中了。这是不是很美好那，其实，要实现这并不难，只要我们多多种树，保护小花小草，实现这就很简单。

让我们的家乡真正变成零污染吧，让我行动起来吧，不要让这只是幻想吧!

早晨，我背着书包走进校园。

Morning, I entered the school with a bag.

路两旁的花坛里，苍翠的青松，墨绿的冬青，在寒风中左右摇摆。

叔叔也笑着夸我："你真是一个爱护环境的小卫士。"

Uncle smiled and said I: "you really are a guardian to protect the environment. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

Economic development and environmental protection are a pressing issue primarily for developing countries where, in trying to catch up with developed countries, they have to consume natural resources on an unprecedented scale. This has seriously polluted our environment and, with the global environmental campaign gaining momentum, many people in China call for the precedence of environmental protection over economic development.

Any attempt to pose economic development and environmental protection as diametrically contradictory is simple-minded. Since no country is willing to stop its economic development, the best way is to strike a balance between the two and to heighten the environmental awareness of those solely concerned with economic development.

European countries both economically developed and environmentally friendly can serve as perfect examples for China. Their success story in both undertakings illustrates that environmental protection does not mean a complete standstill of economic activities or exploitation of natural resources, but rather an active development and application of effective technologies to minimize environmental consequences. In Germany, environmental protection has become part of economic development as it boasts the world s most successful environmental industry. With a developed economy, we are well equipped to develop sophisticated technologies that can effectively safeguard our environment.

There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

大家都知道我们我们盐城是著名的鱼米之乡风景及其优美,可我们的城市流动风景———公交车却屡杀风景,几个主要干道上的车都是属相“乌贼”的,一启动或一加速车尾就喷出一股黑烟,弥漫整个街道,苦了跟在后面的行人和骑车人.

盐城公交车排污已成城市污染杀手,我对此深有感触,尤其行人、骑车人（一些人夏天也不得不戴口罩）.一些公交车辆超标排污现象严重,街面上时常泛起浓浓的黑烟,以及轰轰的噪音（有关噪音显示牌每当公交车经过时高达80多分贝）,路人掩鼻而过.在此我呼吁：我们应少乘公交车或对公交车进行有效的改装使其排放尾气的量大大减少,让我们与交通部门共同努力共创一个美好而又和谐的绿色盐城.

我们的盐城是一个文明的交通都市,作为一个文明的盐城人我们应遵守交通规则,但我们中就偏偏有一些不文明之人经常违法乱纪,妨碍交通,最终酿成了悲剧.

例如八月四号上午九时零二分,在宁靖盐高速公路盐城西出口南约3公里处,一辆上海开往滨海的沪ag6385大客车发生交通事故,导致4人死亡,23人受伤.初步调查,事故原因是该车为避让一横穿公路的老年男子,转向、紧急制动后致客车撞穿右侧防护栏侧翻.这都是由于那位不遵守交通规则的老年男子所造成的悲剧呀,他这一不文明的举动不仅污染了我们的环境（汽车爆炸后会产生许多的污染物从而使大片地区遭受污染）,还使许多鲜活的就这样白白的丢失了.作为一名文明的城市公民我们应时时刻刻都遵守交通规则,或许就因为你的一个不留神,一场悲剧就发生了.让我们携起手来共同成为文明的公民吧,让我们这一片美丽的土地收到我们悉心的呵护吧!

“保护环境,人人有责”这句话虽然简短但却诠释了做一个文明的公民应做的事,我们应让这句话变成一颗环境保护的种子让他在我们的心里发芽,形成强烈的环境保护意识,让这一片沿海风光重回亮丽光彩,让这美丽的蓝天重回天朗气清,让这文明的都市重回水木清华.

有一天，小燕子要找小鱼说一件事。小燕子找啊找啊，终于找到了小鱼。小鱼正要浮出水面上呼吸，可水面上的空气也被污染了。小鱼说：“唉！你看看我们的城市全都被污染了。”小燕子说：“是啊，我们的旁边有一个厂子，每一天厂子里的烟囱就会冒出大量的烟雾，都快把太阳给遮住了，而且也造成了植物的死亡。”小鱼说：“你看看，我们的小河到处都是垃圾，都把水给污染了，所以我们才把头伸出水面来呼吸。”小燕子说：“不过天空的空气也被污染了。”小鱼和小燕子说：“保护环境，人人有责。”

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。

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。

How to protect the environment

Its very impont for us to protect the environment good environment can make people feel happy and fit.To improve the environment means to improve our life.we should plant more trees and flowers around us.we shouldnt cut them down.we should stop factories from pouring west water into river.Dont draw on public walls.After all,its our duty to protect the environment.We hope our world will become more and more beautiful.

Protection of the Environment Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive. We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products arestill put into rivers. We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycie them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.
