英语作文：人类活动破坏了环境（合集20篇）

We all know it is becoming more and more important to protect our environment well.We should stop cutting down trees ,dropping litter everywhere and throwing waste before it is processed. It has caused lots of problems such as much rich land becomes desert;Rivers become dirty ;The air is becoming worse and worse ;The temperature is becoming hotter and hotter.So we must do something to change the situation.Wed better walk or ride bikes to work or go to school instead of driving a car,We mustnt use plastic bags.Our government must take some measures to prevent factories producing smoking etc.

School is our second home, where we spend the majority of time living and learning. Therefore, a good school environment is the precondition for our health and growth.

However, I am sorry to have witnessed some improper behaviour among us students: scribbling and littering everywhere. Not only does it destroy our school environment, it is also a spoiler of the image of our school.

This issue is now crying out to be solved and it should be a common concern for the school administration, staff, and all the students. In my humble view, the school should place more dustbins around the set up specific rules against those rude practices. At the same time, students should be encouraged to develop good habits and enough awareness of environment protection.

I hold a firm belief, with the joint effort of all people concerned, that our school will become a more enjoyable place in the near future. I am looking forward to a more tidy school, and a more beautiful world.

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.

人类的生存与发展离不开环境，然而，人类在谋求自身的生存与发展的同时，不断地将生态破坏和环境污染带给地球家园。随着人类改造自然的力量日渐强大，人类环境的破坏变得日益严重，人地关系矛盾加剧，现已危及人类自身的生存。

我们不能以牺牲环境为代价来换取一时的经济繁荣，不能徘徊在无知和狂妄之间对大自然苛求无休。我们既不是大自然的奴仆也不是大自然的主宰。

面对日益严重的人口、资源与环境问题，人类开始反思以往的行为对地理环境所造成的严重后果，重新认识人类与地理环境的关系，逐步构建了人类与地理环境的新型伙伴关系—人地伙伴论。让我们以可持续发展的理念和发展模式，在谋求生存与发展的同时，认识和解决好环境问题，永远与自然和谐相处。

在我们居住的地球上，自然资源的形成与演化，往往需要经历漫长的发展过程。人类无休止的“征服”自然和“索取”资源，以掠夺性的生产方式，造成了资源和生态环境的严重破坏。在世界经济高速增长的今天，大自然向人类亮出了“红灯”。

我们无法阻止前人浪费资源、破坏环境，就像后人也无法阻止我们去犯同样的错误。如果我们不能阻止当代人自毁家园的愚蠢行为，那么我们的子孙后代也无资源可用，无立足之地！

人类已经警醒，世界正在行动。珍惜自然资源、保护生态环境是我们义不容辞的责任。把青山留给大地，把洁净留给天空，把绿荫留给小鸟，把沃土留给子孙……让我们在与自然的和谐共处中，求得永续发展。

当我们陶醉于人类创造的现代文明，庆贺“征服”大自然伟大胜利的时候，各种有形、无形的环境污染正从四面八方悄悄袭来：工业“三废”污染、化肥和农药污染、生活垃圾污染、恼人的噪声污染、眩目的光污染、“无形杀手”电磁波污染……毒害着我们健康的肌体，破坏着我们美好的家园。

生存还是灭亡？人类面临着严峻的挑战。

觉醒吧！人们，勇敢的直面环境污染带来的生存危机。行动起来吧！人们，重建我们美好的家园。

仰望星空，茫茫宇宙，目前地球是人类唯一的家园。放眼全球，人口爆炸、森林锐减、水源污染、土地退化……

我们难以恢复地球往日的洁净。然而，重新营造一个美好的生存世界又是何等艰难。

20世纪70年代以前，对于环境问题采取的主要措施是限制污染物排放和治理污染源。然而在实践中，人们逐步认识到环境问题并不是单纯的污染问题，仅仅采取工程技术措施不能从根本上解决环境治理问题。

保护环境是全人类的共同任务，没有国际间的广泛合作，没有各国政府制定的法律、法规，没有广大公众的积极参与，就不能从根本上治理环境污染和生态恶化。向环境污染宣战，做坚定的环保卫士，是我们每个人责无旁贷的使命。

从我做起，从现在做起，从身边的小事做起，用全人类的共同行动创造地球更加美好的明天！

Those large floods deprived of the lives of many people, and because of the greenhouse effect, the Antarctic Arctic glaciers melt the water level, the sea flooded the coastal areas, the economic losses. Is not this the best proof?

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.环境污染现象英语作文二

As a college student,I can be responsible to say that all my classmates dream about getting a satisfying job,and devote themselves to this career in an perfect environment.Certainly I am not an exception too,though nowadays there is a growing employment pressure . For many students, a satisfying work environment may be the aim of four-year college life,I also hope I can work in a colorful and competitive climate in the future .At first,I can get a handsome salary so that I live a comfortable life .Although salary is not the main factor , most of people they cannot neglect salary,because job with low salary cannot hold water for the young men . Whats more, I can learn more working experience and get a wide view to increase my knowledge，because I think there is no limit to knowledge and if one person wants to take a great progress in his career learning is the only way .In finally ,I hope I can meet a competitive opponent.There was a saying by Charles darwin:” It is not the strongest of the species that survive,but the one most responsive to change”.So I think competition is conducive to progress. There is no doubt that everybody want to get a perfect job,but employment pressure has been a problem that we cannot overlook.So we have to spare no effects to improve ourselves ,I believe that we can get a satisfying job as long as we constantly strive to study.

同学们，你们可能都认为一个小小的方便袋，没有什么污染，这你们可就错了。一个再小的方便袋也能污染水源。

在白城市每户人家差不多一年就能用100多个方便袋。白城市要是只有100多户人家，大约每年都要使用一万个方便袋。大家想想咱们白城市光有100户人家吗?在学校上课时，我每天都要随身带一种水果。可是水果的外包装是一种塑料做的小食品袋这种方便袋对环境的污染十分严重。并且我们一般只会一次性使用它。用过的袋子就进了废品收购站。但大部分却被弃入了我们的大自然当中。

我希望人们少用一些方便袋改用一些布袋，减少一些白色污染，请大家爱护我们的家园，救救生存的地球母亲吧!

假如人类不顾后果地滥用化学品，那么自然资源不能再生;假如人类一味砍伐树木，就会导致今天的荒漠;假如人类不保护生物，生态平衡受到破坏。假如人类随意毁坏自然资源，就会造成一系列生态灾难……那可是一件多么可悲的事情啊?!

假如人们不保护环境：工厂里的污水大量排进地球的江河湖泊里，地球妈妈“贫血”了;人类不知疲倦地砍伐树木，不仅会造成水土流失，首都北京等周边的地方还会造成严重的沙尘暴，导致荒漠;矿物被无限制地滥采，破坏了耕地和水源;大气层中的臭氧层也由于人类的原因，出现无法弥补的大洞;许多生物物种频临灭绝，华南虎、丹顶鹤和扬子鳄等稀有动物在世界上已寥寥无几;假如人类继续这样下去，就会给人类生存带来了严重的威胁。若是，人类就会把地球几十亿年来的积蓄全部用光，加快人类的灭亡。

假如人们在报刊、书籍、网络、电视上都宣传保护环境，让所有人都意识到危害环境所造成的一系列生态灾难。工厂里的污水和废气都不排进江河湖泊和天空，妥善处理，并建立污水、废气站，污水再利用：浇花、冲洗厕所、擦地……那么江河湖泊的水会又黑又臭吗?不乱砍乱滥伐，都多举行植树活动，每位老师、父母都教导学生及小朋友有保护环境的意识，到处绿树成阴;不滥用化学品，尽量少用，使毁坏的资源再生;限制滥采矿物，使耕地和水源不受到破坏;只要从小养成保护动物的习惯，生物物种就不会灭绝。只要这样做，生活就变得更美好。

假如人类都保护动物、多植树、妥善地处理好工厂的污水、废气……世界就会鸟语花香、气候怡人、多姿多彩。生态灾难是由人类自已直接或间接制造的，所以我在此呼吁大家：我们一致行动起来，保护我们人类赖于生存的家园——地球!

industrial pollution is the industrial production process of the formation of gas, waste water and solid emissions on the environment pollution. industrial pollution is mainly concentrated in a few industries. paper, chemical, steel, electricity, food, mining, textile and other seven sectors accounted for the total wastewater discharge 4 / 5. paper and food industry accounts for cod emissions of cod emissions 2 / 3, non-ferrous metallurgical industry, heavy metal emissions of heavy metals emissions account for nearly 1 / 2. industrial pollution is the industrial enterprises in the production process, including human biological survival and reproduction of the natural environment against. pollution is mainly from the production of the "three wastes" (waste water, waste gas, waste) and all kinds of noise caused can be divided into water pollution, air pollution, waste pollution, noise pollution.

We cant live without water, but now the water was polluted. It is the biggest problem. It influences our daily life. So we should find a way to solve this problem. Water is important resources. In our daily life, we often leave the tap on after cleaning hands. Sometimes we often drop litter in the river. So the water was polluted by us. I think we could use a bottle of water two or three times. We have to turn off the tap after cleaning hands.

Lets try to form a good habit and save things around us. Lets do it from now on!

Water is very important to us. We cant live without water. But the drinking water is less and less. Because we waste a lot of water in our daily life. And some of us often throw rubbish into the rivers. So the rivers are polluted seriously.

Its our duty to save water, we must do something to save water. For example, we shouldnt pour waste water into the rivers and we should pick up litter around us.

If we dont save water, the last drop of water will be our tear.

Fish cant live without water. Plants cant live without water. People cant live without water, either. As you can see, the water is very important to us. But now drinking water is less and less. The water was polluted seriously.

Its our duty to try our best to protect and save water. And dont forget that if we dont save water, the last drop of water will be our tear.;

If we dont save water, the last drop of water will be our tear. What a frightful announcement!

Water is very important for people, animals and plants. Water is needed to many things in daily life, like taking a shower, drinking, washing clothes, making meals and so on. We cant live without water. But now water has become less and less because people waste water and pollute water. If we continue to do things like this, we shall destroy ourselves. So we should take action to improve the environment quickly. We shouldnt throw rubbish into the rivers. We should pay attention to environmental protection. We can use less water when we wash something. In a word, we should save water.

没有水我们无法生存,但是现在水被污染了。这是最大的问题。它影响我们的日常生活中。所以我们应该找到一个方法来解决这个问题。水是重要的资源。在我们的日常生活中,我们经常离开水龙头清洗后的手。有时我们经常在河里乱扔垃圾。所以我们的水被污染了。我认为我们可以用一瓶水两到三次。我们必须关掉水龙头后清洗双手。

让我们试着养成良好的习惯,节约我们周围的事情。让我们从现在开始吧!

水对我们是非常重要的。我们没有水是无法生存的。但是,饮用水越来越少。因为我们浪费大量的水在我们的日常生活中。和我们中的一些人经常把垃圾扔进河流。因此,河流污染严重。

节约用水是我们的责任,我们必须做些事情来节约用水。例如,我们不应该把废水倒进河流和周围我们应该捡起垃圾。

如果我们不节约用水,最后一滴水将是我们的眼泪。

鱼没有水是无法生存的。植物没有水是无法生存的。人没有水是无法生存的。正如您可以看到的,水对我们是非常重要的。但是现在饮用水越来越少。水被污染严重。

所以我们将迅速行动,以拯救水,但是现在我们必须做些什么?我认为我们可以植树,干净的河岸,通过用水浇灌植物。关掉淋浴当我们洗头发。我们不应该乱扔垃圾到河里,等等。

这是我们的职责尽力保护和节约用水。别忘了,如果我们不节约用水,最后一滴水将是我们的眼泪。

如果我们不节约用水,最后一滴水将是我们的眼泪。多么可怕的消息!

水对人们是非常重要的,动物和植物。水是需要很多东西在日常生活中,如洗澡、喝,洗衣服,做饭等等。我们没有水是无法生存的。但是现在变得越来越少,因为人们浪费水,污染水。如果我们继续这样做,我们将毁灭我们自己。所以我们应该迅速采取行动来改善环境。我们不应该把垃圾扔进河流。我们应该注意环境保护。我们可以用更少的水当我们洗东西。总之,我们应该节约用水。

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

保护环境是我们的义务。我们居住在哪里？地球。地球是我们唯一居住的地方，所以可想而知环境对于我们的重要性。

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

但是现在，很多人都在破坏环境，比如砍伐树木，在公共墙壁上乱涂乱画，随地扔垃圾。如果我们继续这样下去是非常可怕的。

现在，是人们保护环境的时候了，这是我们的义务，我们都要为改善环境做贡献，我们应该努力让我们的环境变得更好。

我们人类生活在地球上，地球上有许多东西需要我们保护，但是我们却没有在意。

We live on the earth, the earth there are many things we need protection, but we didnt care.

有些人不珍惜地球赐予我们的一切，例如人们乱砍乱伐，大量使用一次性筷子和乱扔塑料袋，制造白色垃圾等已经给大自然带来了许多环境问题，严重影响了我们的生活。还有大气污染，酸雨和臭氧层等带来的危害都是大自然给人类带来的灾害，人们乱砍乱伐，乱扔塑料袋和使用一次性筷子等，这些就是人们不尊重大自然而造成的，没有自然，便没有人类。这是世界一大朴素的真理，人们只会一味的抢夺自然，征服自然，只会破坏生态系统，咎由自取，使人类濒于困境。切记，保护环境就等于保护我们自己生存的环境。

Some people do not cherish the earth gives us all, for example, people cut down many trees, the extensive use of disposable chopsticks and throw plastic bags, producing white garbage has to nature brought many environmental problems, a serious impact on our lives. There are air pollution, acid rain and the ozone layer damage caused is human nature to bring disaster, people cut down many trees, throw plastic bags and disposable chopsticks, which is that people do not respect the nature and cause, no nature, no human beings. This is a big world, plain truth, people just blindly grab the nature, conquer nature, will only bring trouble to oneself, the destruction of the ecological system, humans dilemma. Remember, Protect environment is to protect our own living environment.

我们要保护这个脆弱的的地球，不要让茂密的森林，辽阔的草原和无边无际的海洋成为我们的回忆。

We want to protect this fragile earth, dont let the dense forests, vast grasslands and boundless ocean has become our memories.

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(保存) our natural resources and recycle(再循环) our products. We are sure that we can have a better and cleaner place in the future.

今天,自然环境质量已成为一个重要议题。世界人口增长如此之快以至于世界已经变得太拥挤了。我们正在用尽自然资源,同时,用化学危险品污染环境。如果我们继续这样做,地球上的生命将无法继续存活。

有关人员有了一些进展在环境保护。许多国家的政府都制定了法律以保护空气,森林和海洋资源并停止环境污染。

更多措施应该被采取解决环境问题。受过教育的人应该是进一步认识问题的重要性,要运用现代控制生育的方法来保存(保存)我们的自然资源和循环(再循环)我们的产品。我们相信,我们可以有更好的和比较干净的地方,在未来的。

On Friday afternoon, the activity class began. We should have in the interior of the standing long jump, can our teacher have led us to epoch-making outdoor activities.

The teacher said: "boys and girls, two teams, come to a game, jump over, see which team first to the opposite." We are all leaping like a happy chicken. As a result, the boy team jumped and jumped into a mess, and I was also pressed into a "meat pie" by Ye Zuhui and others behind. But the boys are still winning, after all, is it a mans strength to run and jump! From time to time, the boys showed a triumphant smile and a joyful cheering from time to time.

But the girls, each pointing to our boys face, said: "the team is scattered, the win is not brilliant!"

The teacher also announced, "now race running, see who runs fast!" Prepare - start! We ran away like wild horses that had taken off the reins. Some of the students can see that they can run away from the runway and run to the end of the race. I have straight teeth, shouted: "who is not a shameless man!" But they listen to me, only if they dont hear them.

When everyone arrived at the end, the teacher said, "go back to the class, and then go down this way."

Although only a few short minutes, it has brought me a lot of happiness, left a deep impression.

This summer vacation, I joined a social practice to be a part-time tourguide. There I found something that impressed me a lot.

People who love traveling are always finding places to take a vacation, which caused a lot of troubles.For example, I found that some people were used to dropping out the trash everywhere. They just regarded the sightseeings as their houses, which cost a lot to clean it up. Besides, some one should write down their names on the trees and walls. People who wanted to leave their names whereever they went are always to punish in future.

Nevertheless, I also found some good examples, such as teaching tourists not to destroy the places of historic interests, helping clean up the environment,etc..I think we all need to teach more people not to hurt our precious nature. What we really need to do is protect them form destroying.

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。

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!
