汽车带来的环境污染英语作文【20篇】

Now, patches of forest became less factories. Endless grassland into desert, limpid streams into a muddy gutter, beautiful grassland into a barren desert. Why? Why is this? This is because people caused by deforestation.

The earth is home to the survival of people, and the human is continues to destroy it, people cut trees have purify air, reduce noise and adjust the temperature, and other functions; Being pulled out of the grass and people to remove the flowers to beautify the environment. You imagine, if it were not for the plant, our living environment?

These days, many wild animals has become the plate of food, fine furniture, gorgeous dress. You think about these wild animals to buy me a life brought a lot of fun, without these lovely animals, our life will become special boring. Rose up in the morning, cant hear the birds chirping and crisp sound, cant see the kitten doggie smile to you, can only see the strange and hard faces, that is bad!

Let us join hands together to create a beautiful home! Let us see the mountains again, flowers everywhere, singing birds, vibrant scene! Let our life more beautiful environment, more interesting. Let the flower and grass fragrance our lives "to protect the environment, everyone duty", believe in the near future will be a new world, we create a beautiful earth. Everyone must do "protect the environment, everyone duty."

现在，片片森林变成了座座工厂。一望无际的草地变成了荒原，清澈的小溪变成了浑浊的臭水沟，美丽的草原变成了贫瘠的沙漠。为什?这究竟是为什么?这是因为人们乱砍乱伐造成的。

地球是人们赖以生存的家园，而人类却在不断的破坏它，被人们砍伐掉的树有着净化空气，减小噪音，调节气温等功能;被人们拔掉的小草和被人们摘掉的鲜花能美化环境。大家想象一下，如果没有这些植物，我们生活的环境会怎样?

如今，许多野生动物成为了人们盘中的美食，精致的家具，华丽的服饰。大家想一想这些野生动物给我买的生活带来了许多的乐趣，如果没有这些可爱的动物，我们的生活就会变得特别无趣。早晨起来，不能听到小鸟叽叽喳喳清脆的叫声，不能看到小猫小狗向你微笑，只能看到一张张陌生而生硬的面孔，那多不好啊!

让大家携起手来，共同创造这美丽的家园吧!让我们重新看到青山绿水，鲜花遍地，百鸟欢歌，生机勃勃的场面吧!让我们的生活的环境更加美好，更加有趣。让鲜花和小草芳香我们的生活“保护环境，人人有责”，相信不久的将来地球将被我们创建成美丽的新天地。大家一定要做到“保护环境，人人有责。”

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。

哦!家乡变了，家乡变了，我怀着无比激动的心情来到家乡。

下了车，眼睛突然一亮，哇!家乡简直是梦幻美丽的天堂。

眼前，是一排排苍翠挺拔的大树，像一位位士兵守卫着这梦幻般的仙境。

脚下的路更加宽阔平坦，不再蜿蜒崎岖。

向前走10分钟，一条清澈见底的小溪便印入眼帘，水底的鱼虾清晰可见，它们无忧无虑地在小溪里穿梭，快乐的好像神仙一样。

在阳光的照耀下，水面破光粼粼，像一面洁白无瑕的璞玉。

小溪旁，是一片翠绿的草坪，几棵小草，伸着懒腰，从土地里钻了出来，探视着这五彩缤纷的世界;小花涨红了脸，呼吸着春天的香气息。

家乡的变化可真大啊!想当年，家乡的环境十分恶劣：山上，一群肌肉结实，身体强壮的年轻男子，拿着一把把锋利的电锯，无情地把高大粗壮的树木砍伐一空。

生活在山林的小动物都仓皇而逃，过着定无居所的日子。

生活在小溪旁的人们更受着百倍的煎熬，溪水恶臭浑浊，鱼虾奄奄一息。

溪旁的小草面黄肌瘦。

无精打采，小花也垂头丧气，没有了往日的生机。

更恐怖的是，环境的污染使得可怕的自然灾害降临到家乡。

瓢泼大雨使山体滑坡，严重的泥石流，造成了许多人财产受损。

幸亏人们对家乡长生了保护意识，在荒山上植树造林，把小溪的垃圾清除一空……这才把家乡从死亡的边缘拉了回来。

我们美丽的家园需要爱，请保护环境吧!让我们的地球永远拥有美丽、青春的活力。

With the rapid development of science and technology, human demand for resources is increasing, causing the Antarctic arctic ice melting speed, rising sea levels, the Antarctic ozone hole, increasing dust storms in Beijing, haze weather, the Japanese earthquake nuclear pollution...

When we enjoy the good life at the same time, the thought of the importance of protecting the environment?

So, please keep an eye on our campus, look! The playground, school gate, stair aisle flying confetti, food bag, bottles; Look, those teeth bared on the white wall graffiti... These are not harmonious scene and our campus civilization!

The classmates, if we all take action, to be the master of environmental protection, do not throw confetti, peel, graffito of the scribble not, casually picked up confetti trash on the ground, take good care of the environment, our campus is dressed up beautifully and. When we walk on the tree-lined campus path, will feel relaxed and happy; When we study in bright classroom, will concentrate; When we study in the clean and elegant environment, will feel better.

Beautiful environment, let us know how to cherish, learn to cherish; Beautiful environment, let us knowledgeable and more civilized; Beautiful environment, let us learn to obey, learn to be a person; Beautiful environment, let our moral, make our learning more progress!

随着科技的高速发展，人类对资源的需求越来越多，致使南极北极冰雪融化的速度加快、海平面日渐上升、南极出现臭氧空洞、北京的沙尘暴、雾霾天气不断增加、日本大地震后造成的核泄漏污染……

当我们在享受美好生活的同时，是否想到保护环境的重要性呢?

那么，请同学们关注一下我们的校园，看!操场上、校门口、楼梯过道上漫天飞舞的纸屑、食品袋、饮料瓶;瞧，雪白的墙壁上那些张牙舞爪的涂鸦……这些都是和我们校园文明不和谐的一幕啊!

同学们，如果我们大家都行动起来，争当环保的主人翁，不乱扔纸屑、果皮，不乱涂乱画，随手捡起地上的纸屑垃圾，爱护环境，把我们的校园装扮的漂漂亮亮。当我们在绿树成荫的校园小道上漫步时，一定会感到心旷神怡;当我们在窗明几净的教室里读书时，一定会全神贯注;当我们在整洁优雅的环境中学习时，一定会心情舒畅。

优美的环境，让我们懂得珍惜，学会爱护;优美的环境，让我们知书达理，更加文明;优美的环境，让我们学会谦让，学会做人;优美的环境，让我们道德高尚，使我们的学习更加进步!

今天我来到了我爸爸上班的地方张集。张集是一个小镇，它是我的老家 。

Today I went to my father work place Zhang ji. A set is a small town, it is my hometown.

小时候我在那里住的时候，环境特别的不好。人们根本不保护环境。垃圾四处‘‘流浪’’，屋前屋后、路旁岸边都是垃圾的家。夏天苍蝇蚊子大聚会，散发出浓烈的腐臭味，人们过路时得捂着鼻子才行。冬天寒风吹来，纸片、树叶、塑料袋漫天飞舞，真像‘‘天女散花’’，人们不戴口罩眼镜还真不敢出门呢。

When I was a child living there, especially bad environment. People dont protect environment. Garbage everywhere wandering , house, roadside banks are rubbish home. Summer flies mosquitoes big party, stink smell strong, people crossing the road when a clutching his nose it. The winter wind blowing, leaves, paper, plastic bags flying all over the sky, like The heavenly maids scatter blossoms. , people dont wear masks glasses really dare not go out.

如今沙漠正在急剧扩大，人们也已经知道了保护环境的重要性。瞧，现在张集就像一个大森林，街道上干干净净，没有一点灰尘。绿树成荫，鲜花盛开，空气清新，天空湛蓝。

Now the desert is expanding rapidly, people already know the importance of Protect environment. Look, now a set like a forest, the streets clean, no dust. Trees, flowers in full bloom, the air is fresh, the sky is blue.

你看，如今我们在这么好的环境下生活，多么幸福啊，我们要把保护环境进行到底，让老家永远那么美丽。

You see, in such a good environment we live now, how happy ah, we want to Protect environment through to the end, let the home is always beautiful.

人类在变好，环境也在变好，让我们的环境一直好下去吧。

The human is changing, environment is also good, let our environment have been down.

The Surroundings in Cities

We have to admit that, comparatively speaking, our cities are not so clean and green as those in the developed countries. There are not adequate trees, lawns and flower-beds in such big cities as Beijing,Tianjin and Shanghai.

We should make our cities greener by planting more trees, grass and flowers. A green enviromnent can bring us pleasure, beauty and fresh air. Trees, lawns and flowers will make our cities more pleasing to both the eye and the mind, improve the weather conditions and provide fresh air, all of which will no doubt do us a lot of good.

I suggest that the whole city go all out every spring to plant new trees, build new lawns in and around the city, and everyone should take care of and protect the trees, lawns and flowers, and educate the children to love them. Then year after year, our cities will become greener, more beautiful and liveable.

[城市的环境英语作文

污染环境的人们：

地球妈妈是什么？地球妈妈是一部洒满热血与热泪的历史长卷，地球妈妈是生命的摇篮，是哺育着无数代子孙的母亲，地球妈妈是一道美丽的风景，地球妈妈是一支绵延无尽的歌……原来的她，美丽而纯洁，被小辈们装饰得漂漂亮亮。而现在呢？现在的地球妈妈被那些不顾后果地污染环境的人们弄得危在旦夕。地球是我们人类赖以生存的家园，它无私地为我们提供着生存资源和条件。我们应该要爱护地球，珍惜地球，而那些污染环境的人呢？有的在各个地方摆摊而等到晚上就收摊走人。但是他们却没有看到在他们周围到处都是他们丢弃的垃圾，等到再过几天，那些垃圾在地上发臭，苍蝇、蚊子都飞来飞去，让过路的行人都得捂着鼻子，快步走过去。有的在一个干净的小花园里扔垃圾，渐渐的有许多人往那里扔垃圾，那里就成了一个垃圾堆了。原来，那里绿树荫荫，花儿和小草茂盛地开着。蜜蜂和蝴蝶都在那里安了家，那里到处散发着迷人的气息，犹如一副美丽的画卷。可是现在，那里寸草不生，臭气熏天，连人都不愿意在那里多待一会儿……为了保护我们美丽家园的环境，向你们提出以下几点建议：

1、提倡人们不乱扔垃圾，应把垃圾扔到指定分类的垃圾箱里。并加强宣传分类垃圾箱的可回收范围内的物品和不可回收范围内的物品。

2、教育广大市民要节约资源，并大力宣传一些节约资源的小窍门。

3、强化监督管理，要让人们做到尊重自然，爱护树木，爱护动物，爱护大自然的一切。如果发现身边有破坏环境的人，应及时教育和积极提醒。

4、提倡人们多点使用耐用品，绿色消费。尽量不要使用一次性用品。

5、宣传“从我做起，保护环境”。可以的话开一些保护环境的活动，让人们体会到，环境对于我们人类来说，真的很重要。

谁不希望抬头所望的天空是湛蓝如玉，谁不希望脚下宽阔的大地是绿草如茵，谁不希望身边的湖水是清澈如镜，谁不希望扑鼻而来的空气是清新如洗，谁不希望照耀大地的阳光是灿烂如金？“污染环境千夫指，保护环境万人颂。”只要我们保护环境，珍惜资源，我们的地球还是一个充满缤纷色彩的世界，还是我们人类美丽的家园！

[对于污染环境的建议书

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!

Humans have only one earth. He is the cradle of life, is the homeland of all mankind. However, the environmental pollution and ecological destruction have on human social and economic development and peoples normal life constitutes the real threat. Take good care of the environment, advocate civilization, is the human moral and responsibility.

We want to clean the earth, eager to healthy earth, eager to the homes of environmental protection, eager to green, health, community health... Let us use love to pay attention to changes in the environment, with passion to spread the idea of environmental protection, with actions to shoulder the important task of environmental protection. Starts from me, start from now, intravenous drip minor matter, starts from the side the environmental commitment into action.

Remember, protect the earth, is to protect ourselves.

人类只有一个地球。他是生命的摇篮，是人类共有的家园。然而，环境污染与生态破坏已经对人类的社会经济发展和人们的正常生活构成了现实威胁。爱护环境，崇尚文明，无疑是人类自身的道义和责任。

我们渴望干净的地球，渴望健康的地球，渴望环保的家园，渴望绿色，健康，卫生的社区……让我们用爱心去关注环境的变化，用热情去传播环保的观念，用行动肩负起环保的重任。从我做起，从现在做起，从身边的点滴小事做起，把环保承诺变为实际行动。

记住，保护地球，就是保护我们自己。

家乡变了，真的变了!天空变暗了;小鸟变少了;小河变浑了，就连鱼虾都“躲”了起来。

家乡变的原因还是冒滚滚浓烟的打样囱和污水。这几年来，工厂不断的生产，废气从烟囱里冒出来，污水不断从管道里淌出来。还有就是人们乱堆垃圾，把地球的“外衣”破坏了。就这样，家乡被污染了。

小河在哭泣，哭泣自己没有伙伴;小鸟在呼吁，呼吁自己美好的家园;地球在痛苦，痛苦自己没了外衣;

我知道，原来家乡不是这样的。原来的家乡天是一片碧蓝，河是清澈见底，鱼虾自由自在，鸟儿成群飞翔。而现在呢?现在的家乡已不是昔日的家乡了，现在……

小鸟呼吁人类：人类，请你们不要把树木砍伐，让我们无家可归，四处流浪。我呼吁人类：请你们不要把垃圾四处乱丢，让空气变的浑浊，请你们为自己想一想，如果哪一天空气没了，你们会怎么样?

让我们一起保护自己的家园，不要让家园的环境再变难看，而要让家乡的环境变得更美!一起行动起来，为自己创造一片蓝天吧!

Protecting the environment and taking care of the earth is something we all should do.

Recently there are a lot of environment has been destroyed, around us there are many people in the destruction of the environment, cut down the trees, the birds were killed, flowers and plants have been burned, it is one thing for our warnings, the forests are disappear in every 375 square kilometers, the desert is evolving, flooded the countless individuals every beautiful homes, precious and there are ancient animals are killed, the panda has now been arrested, and so far only 1000 only, although there are a lot of people have built consciously protection station, but there are still some people for money by hook or by crook the killing of animals, birds no longer common, because being grabbed, trees less, because being cut, please protect them! If you go on like this, again, and the future of the animals we have learned in a book, according to people each with experts observation, day and night, a protective layer in the sky, the ozone hole, is because of the large hole lead to global warming, and the year before become very hot in the summer, many people died in the heat.

All this is because people open super sound emitted by aircraft emissions of waste gas and the car tail gas is left at the trial of toxic substances in the air into the results, if in so doing, the glaciers will melt, make the surface flat area, causing most of the land of the sea submerge.

If you dont stop cutting trees, when the trees were cut down light, desert will evolve, without the tree represents no oxygen, and the air was full of carbon dioxide, make the person cannot breathe, cause a person to cant live.

Please do not cut down trees, let the birds have a home, do not emit waste gas, let us live together in this beautiful earth!

Low-carbon life means a kind of lifestyle in which people do their best to reduce energy consumption and carbon dioxide emissions.

Then，how can we live a lowcarbon life?Firstly，we should recognize that the lowcarbon life is not only a kind of lifestyle but also a life attitude.Each of us is responsible for the greenhouse gases in our daily actions.To combat climate change we have to take the combined efforts of everyone on the planet.Secondly，we should develop good habits in our daily life.Paper cups are made from cutting forests.We should try not to use them because trees can absorb carbon dioxide and reduce greenhouse gases.Similarly，lights should be turned off when they are not used，which will greatly reduce electricity consumption.

In a word，small actions above can make a big difference.

The earth is our mother, is the survival of our homes. With the improvement of living standards, while enjoying the human, but unknowingly destroyed her, our living environment is deteriorating.

At ordinary times is ok, we eat a piece of gum, chewing freely to spit on the ground, after chewing gum stuck firmly on the ground, cleaning workers to use shovels to get it off, and gum also pollute the land. We often when shopping, use large and small plastic bags, plastic bags but dont know by fire, and produce toxic gases after the landfill is not easy to degrade after, can also lead to land is destroyed, the population of China is so much, you can imagine how many plastic bags in the pollution of our environment.

A persons environmental action is like a lamp, when everybody lit the lamp, the whole world would be bright! Lets get started! Dont eat chewing gum; Dont use plastic bags; Dont use disposable chopsticks... Protect the environment, everyone duty! Let our earth more beautiful!

地球是我们的母亲，是我们赖以生存的家园。随着生活水平的提高，人类在享受的同时，却在不知不觉地破坏她，我们的生存环境不断恶化。

平时没事时，我们就吃一块口香糖，嚼完后随口吐在地上，口香糖牢牢地粘在地上，清洁工人得用铲子才能把它弄掉，而且口香糖也污染土地。我们经常在购物时，会用到大大小小的塑料袋，却不知塑料袋被火烧后会制造有毒气体，填埋后还不容易降解，还会导致土地被破坏，中国人口这么多，可想而知会有多少塑料袋在污染我们的环境。

一个人的环保行动就像是一盏灯，当大家都点燃自己的那盏灯，整个世界就会一片光明!让我们行动起来吧!不吃口香糖;不用塑料袋;不用一次性筷子…保护环境，人人有责!让我们的地球更加美丽!

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.

写作的时候少不了需要事例，欢迎阅读环境污染事例作文哦!

在一些国家，资本家或生产单位的经济人为了追求高额利润，任意向自然界排放各种有害物质，严重污染环境，特别是大气和水源的污染，造成社会公害，引起许多疾病，使广大人民的健康和生命受到严重威胁。

对水源的污染有多种，其中“水俣病”就是举世闻名的日本公害之一。

“水俣病”于1953年首先在日本九州熊本县水俣镇发生，当时由于病因不明，故称之为水俣病。

1950年在水俣湾附近渔村中，发现一些猫步态不稳，抽筋麻痹，最后跳入水中溺死，当地人谓之“自杀猫”。

1953年水俣镇发现一个生怪病的人，开始只是口齿不清，步态不稳，面部痴呆，近而耳聋眼瞎，全身麻木，最后神经失常，一会酣睡，一会兴奋异常，身体弯弓，高叫而死。

1956年在这个地区又发现五十多人患有同样症状的病。

经过对病的调查和研究，在1962年才确定水俣病的发生是由于汞的环境污染，特别是常期食用被污染的鱼和贝类引起的甲基汞慢性中毒。

这是从水俣镇的工厂排放的氯化甲基汞污染海域，使鱼和贝类中毒造成的。

继水俣镇之后1963年，日本新泻县又有大批自杀猫、自杀狗出现。

1973年在有明海南部沿岸的有明町等地又发生了水俣病。

据报导这三次发病人数共计900多人，实际上在日本受害人数远远超过这个数字，仅水俣镇受害居民已有一万人左右。

汞俗称水银，它广泛应用于许多工业部门。

汞及其化合物都是有害物质，尤其是汞的烷基化合物的毒性更大。

汞及其化合物可以通过呼吸或消化系统进入人体污染环境的事例作文。

无机汞进入人身体后，含汞浓度最高的是肾脏和肝脏。

有机汞在人脑中蓄积最为显著，其次是肝和肾

汞中毒后的临床症状即如“水俣病”症状。

造成水污染的工业公害除汞外，还有酚、氰类、铬、砷及某些重金属盐等物质。

这些物质从工厂及科研单位排放出来，造成了严重的水污染。

从而对人类造成的危害在国内外都时有发生。

因此在发展国民经济，加快四个现代化的进程中，一定要注意保护人类赖以生存的环境，防止污染，使人类在优美、舒适的环境中生存发展。

Taking care of our school and

Taking care of our school and protecting our school environment! A clean and pleasant environment is very important, because it can make us healthy and happy.

It’s our duty to protect our school environment. We should clean the school every day. And we shouldn’t drop trash here and there. We should pick it up when we see trash on the ground.

We shouldn’t draw on the wall. If we all like our school the same as we like our homes, our school will be more beautiful. We will enjoy our study better. Let’s protect our school environment from now on, shall we?

"Protect the environment, everyone duty", when it comes to protecting the environment, I think of a thing.

Its a sunny afternoon, my mother and I happily went downstairs for a walk, inadvertently, I found on the green lawn with an old, dirty battery. Battery is harmful to our environment a major killer! A grain of small button battery can be 600 cubic meters of water pollution, the equivalent of a mans lifes water consumption; Section 1 battery rot in the field, can lose one square metre of land utilization value, and cause permanent public nuisance. Think about this, I ran to my mother had said it again, I say again: "mom, I want to throw waste batteries into the dustbin." Mother think I speak very reasonable, I happily run to waste batteries, thought: I really do a meaningful thing! I gently picked up the waste batteries, threw it into the dustbin.

"Not to small and not for good, it is a sin to." As a primary school student, we should start from me, start from small things, start from the side, start from now, pick up every piece of paper on the ground, take good care of trees and flowers, love small animals. Lets go and look for the green world, to make our world a better place!

“保护环境，人人有责”，说到保护环境，我就想起了一件事。

这是一个阳光明媚的中午，我和妈妈高高兴兴地下楼散步，无意中，我发现在绿油油的草坪上有一个废旧的、脏兮兮的电池。电池可是危害我们生存环境的一大杀手!一粒小小的钮扣电池可污染600立方米水，相当于一个人一生的饮水量;一节一号电池烂在地里，能使一平方米的土地失去利用价值，并造成永久性公害。想到这，我跑到妈妈跟前把这件事儿说了一遍，我又说：“妈妈，我想把废电池扔到垃圾箱里。”妈妈觉得我说得很有道理，我欢快地跑到废电池旁边，心想：我真是做了一件有意义的事啊!我轻轻地捡起废电池，扔进了垃圾箱里。

“勿以善小而不为，勿以恶小而为之。”作为一名小学生，我们要从我做起，从小事儿做起，从身边做起，从现在做起，捡起地上每一片纸屑，爱护花草树木，关爱小动物。让我们一起去寻找绿的世界，让我们的世界变得更加美好!

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。

Campus, such as flowers, sending out the intoxicating fragrance, sending out the breath of love; Campus, such as the rain, has nurtured us, training us; Campus such as dreams, so beautiful, so sweet. I love this garden like campus.

"Green campus", to beautify the campus. Our campus change green and beautiful. Appered, picked a flower and grass, a flower bed, added to life, our campus look brand-new.

"The air is fresh, clean and tidy environment, buildings, surrounded by green trees", who dont want to in such a clean, sanitary, healthy growth of the beautiful campus learning? But a variety of reasons, our campus environment is gradually damaged by bad behaviour of some of my classmates. Now in our beautiful campus, there have been some uncivilized phenomenon, some students randomly throw debris-brick, plastic bottles, sunflower seeds, etc. Whenever naughty wind these waste, running here and there, tinkling like a child, helpless, we can only watch them on campus "dance", and even some classmates in the scribble on the white wall and the desk carved, and disorderly spit phlegm, and so on. All this, cannot match with our beautiful campus. See these phenomena, how would you feel? Learning life can make you happy?

There is only one earth. He is the cradle of life, is the homeland of all mankind. However, environmental pollution and ecological destruction of normal life has been on the social and economic development and peoples constitute a real threat. Care for the environment, advocate of civilization, is the humans moral responsibility.

我们渴望干净的地球，渴望健康的地球，渴望环保的家园，渴望绿色，健康，卫生的社区……让我们用爱心去关注环境的变化，用热情去传播环保的观念，用行动肩负起环保的重任。从我做起，从现在做起，从身边的点滴小事做起，把环保承诺变为实际行动。

We desire to clean the earth, to earth for environmental health, home, eager to green, health, the health of the community...... Let us love to pay close attention to changes in the environment, with enthusiasm to spread the idea of environmental protection, with action to shoulder the responsibility of environmental protection. Begin from me, start from now, start from the side of the little things, the environmental commitments into actions.

记住，保护地球，就是保护我们自己。

Remember, the protection of the earth, is to protect ourselves.

不要乱砍树木，不要乱丢果皮纸屑。我们要提倡使用塑料袋，同时，我们要爱护水资源，节约用水。我们应该多用自行车环保，节省石油，减少对石油的高度依赖。

现在每年大家要植三到五棵树，是因为树木可以保护环境，而且可以吸收热量。提倡绿色环境，让我来讲讲：我们应该怎样认识环境的知识。

现在，在我们生活中超市也越来越使用环保袋，这样不仅可以减少空气中的污染；而且我们可以节约塑料袋我们告诉大人们:少开汽车多骑自行车。这样可以锻炼身体还可以减少空气中的污染。我们大家应该节约用水才不会有缺水的痛苦。同时，我们要保护小动物，是为了提倡生态平衡。

我们应该不把废电池乱丢，因为它含有大量金属，也是对大气的一种污染。不随地大小便，因为它是一种污染环境的表现，同时，它是一种不文明的表现。我们不能乱涂乱画，随地吐痰，也是不文雅的行为。

我们应该呼吁周围身边的亲朋好友保护环境，从小事做起。要是身边有水笼头就要去拧紧。不要乱大声叫喊，因为会制造噪声。

保护环境从人人做起，因为保护环境人人有责，让我们一起来保护地球吧。
