环境污染话题英语作文(精品20篇)

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.

Industrial pollution is clearly one of the biggest contributors to our polluted landscapes, at least here in the west. There are plenty of causes of land pollution, from urban and industrial ones, to rural and agricultural sources.

But which kinds of land pollution are the most important? And what can we realistically do to help prevent more pollution?

This part of the site gives an overview of some of the most important causes of land pollution, including industrial pollution.

There are also some recommendations for helping avoid domestic land pollution incidents.

Click here for some good reading on industrial pollution and land pollution causes and solutions.

The picture shows the pollution caused by chimneys of the factories in cities. Often, the sky is covered by large clouds of smoke from chimneys. The air is nearly suffocating, especially in the evening as it becomes cold and the smoke is spreading everywhere. The scene reminds us of the end of the world.

From the picture we can infer that the drawer of the picture intends to convey to the readers that unplanned factories has brought about great hazards to the city air condition. Due to planning mistakes, factories were usually placed in the center of cities, among residential and business districts. Besides, nearly every block has several chimneys for the heating system, which makes the whole city immersed in thick columns of smoke. As a result, respiratory diseases have been reported to be rising and old people dying of the worsening air pollution.

Pollution is really a hot issue in the world. If we don’t take useful measures, we may live in terrible surroundings, and some unexpected results may come out in the end. So, what we should do is to bring down the problems caused by chimneys. For one thing, factories with chimneys should be moved out of the center of the city and it should be made sure that the waste gases are at least not poisonous. For another, other means of heating should be developed to stop using coal. In a word, in the city there should be no coal, no chimney, and no smoke to pollute the air.

In general, there are two way of traveling, private cars and public transportation.

Chinese people should regard public transportation as their first traveling opinion.

First, there are so many people living in this countries that make it so crowded.

If each chinese people own a car, there will be far more traffic jams and accidents, which increase you impatience.

Moreover, there will be far more pollution resulted from cars. Once a car started, it release huge amount of dirty gas and heat, which lead to great pollution and result in green house effect.

Body language is used by people for sending messages to one another. It is very useful because it can help you make yourself easily understood. When you are talking with others,you are not just using words, but also using expressions and gestures. For example, waving ones hand is to say "Good-bye." A smile and handshake show welcome, and clapping hands means congratulations. Nodding the head means agreement, but shaking the head means disagreement. The gestures are accepted both by Chinese and foreigners as having the same meanings.

Different countries have different body language. For example, men in Russia, France and Arab countries kiss each other when they meet, but men in China or Australia shake hands instead of kissing. People in Puerto Rio like touching each other, but people from English speaking countries do not touth each other. If you touch an English person, you should say "Sorry. People in Arab countries like standing close to one another when they are talking, but English people must keep a distance away when they are talking. In some Asian countries, you must not touch the head of another person. In Arab countries, you eat using the fingers of your right land;the left hand is not used at all. In parts of Asia you must not sit with your feet pointing at another person.

When you use a foreign language, it is very important to know the meanings of gestures and movements in the foreign country. Following the customs will help you communicate with people and make your stay there much more pleasant and comfortable.

What human besides destroying forests, dont damage the environment problems? It is not. Now, we should see the seriousness of water pollution. At present, 60% of the country in the world face the shortage of water, 20% of the population is difficult to get clean water, 51% of the people do not have access to sanitary water. This is caused by what? Is, that we are causing ourselves now factories and sewage in our life, not by processing is out. This is not proof of that? According to research, each 1 cubic meter of sewage discharge, 14 cubic meters of natural water pollution. Think of it, this is what a terrible number?

Love nature, the consciousness of environment protection! To do propaganda environmental protection angel! Lets take action to protect the environment

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

我的家乡在洛阳市吉利区。这几年来，我的家乡环境变坏了。

我听说，十几年前河阳广场上的水很清，但是现在却变的半青半黑的。这是为什么呢？

在十几年前，河阳广场上的小河里的水清澈见底，像一面镜子。人们用河里的水浇庄稼。可是现在因为一些工厂把废水排泄到了小河里，还有一些人为了方便，把垃圾扔到了小河里。所以河水才变得又青又黑。我每次从河边过的时候，河水"哗哗"的响。好像在说："乡亲们呀！以前我帮你们浇庄稼、供你们欣赏。你们却不懂得珍惜。"

每当我从小河边走过时，都忍不住想对那些把废水排泄到小河里的人，和把垃圾扔进河里得人说："我们只有一个地球，我们要爱护这个地球，把它变成一个绿色的星球。"

It is reported that tourists to China’s Great Wall can now leave their mark on a fake wall recently built near the real wall in Badaling if they pay 999 yuan.

In China, many visitors have the hobby of carving graffiti on places of interest, especially on some famous cultural relics. Last year I went to the Great Wall and found many people had left names and ugly words on the Wall, which destroys many historic bricks. In my opinion, such people should feel ashamed of leaving their marks on the great relics which were created by our ancestors.

So personally I quite agree with this brilliant project though it has caused criticism from some people. The Great Wall would be ruined one day if we didn’t take any steps to protect it. The fake wall is a really good idea because it will protect our relics as well as making profits from the project.

Behaved Tourism When holiday comes, thousands of people pour into the tourist sites, they want to relax themselves and enjoy the beautiful scenery. But Chinese people have a bad habit, they like to leave some notes on the site, proving them have been here before. Such a behavior has been criticized by the public, because the leaving note will damage the preservation of the tourist site. Most of the tourist sites are part of our country’s historical relics, these sites are priceless, it is everyone’s duty to protect the sites. When we go to travel, we should behave ourselves. First, we need to have the idea that no rubbish being leaved behind when we leave the site. We should take away what we bring, keep the environment clean. Second, no any notes being written in the sites. Though in the old days, Chinese workers like to leave their names on the sites, but now it is a new world, we need to behave ourselves.

近年来，大气污染非常严重，雾霾几乎每天都笼罩着天空，不仅给我们的交通安全带来隐患，而且威胁着人们的身心健康。如何改变这种恶劣的环境，净化城市空气已成为当下人们关注的热门话题。日前，《唐山市重度污染天气预警应急响应预案(暂行)》和《唐山市2013--2017年大气污染防止攻坚战行动实施方案》相聚出台，这项举措足以证实各级政府对环境治理的决心和信念。对此。人们不禁拍手称道。

众所周知，造成大气污染的来源诸多，主要来源有三类：其一是生产性污染，这是大气污染的，例如，燃料的燃烧，主要是煤和石油燃烧过程中排放的大量有害物质，如烧煤可排出烟尘和二氧化硫;烧石油可排出二氧化硫和一氧化碳等;另外，生产过程排出的烟尘和废气，以火力发电厂、钢铁厂、石油化工厂、水泥厂等对大气污染最为严重，还有就是农业生产过程中喷洒农药而产生的粉尘和雾滴。 其二是生活性污染，由生活炉灶和采暖锅炉耗用煤炭产生的烟尘、二氧化硫等有害气体。 其三是交通运输性污染，汽车、火车、轮船和飞机等排出的尾气，其中汽车排出有害尾气距呼吸带最近，而能被人直接吸入，其污染物主要是氮氧化物、碳氢化合物、一氧化碳和铅尘等。环境污染是个老生常谈的问题了，之所以越来越严重，一是污染企业的管理者利益驱使金钱作祟，二是政府部门的打击治理的力度不够。这次治理大气污染各级政府重拳出击，人们称赞之余更是拭目以待。治理生产性污染，政府及相关部门要严格治理，对于超标排放的企业坚决取缔，切不可像“治理大型货车超载交了罚款就放行”，而一罚了之，而且要长效监督，杜绝反弹。

诚然，取缔生产性污染企业，作为普通百姓，你我都是“心有余而力不足”。但是，治理大气污染我们也不能完全依赖政府，一些来自生活性的污染，你我都有责任和义务承担。其实，早几年我们就一直在倡导低碳生活，绿色出行，可遗憾的现实生活中有多少人真正付诸行动?。君不见，都晓得机动车排放尾气污染大气，宁可每天抱怨道路堵停车难，也不愿少开一天车;都知道烧烤食品即污染空气又伤害身体.可那一家露天烧烤不是顾客满盈;明知道生产装饰材料会造成大气污染，损害健康，却有多少人在“豪华”的装修;如此这般，是否在做自己害自己“傻事”。如果你我少开一天车，少用一度电或少用一吨水，这些细小的行为看起来微不足道，但是，倘若每个人都能自觉的杜绝铺张浪费，养成勤俭节约的生活习惯，相关企业就会减少产量，就会间接的较少污染。唯有政府的治理和你我的参与，我们的生存环境一定有所改善，天空才会越来越蓝。

The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earths vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time, the opposite effect, in which life actually modifies its surroundings,has been relatively slight. Only in the present century has one species--man acquired significant power to alter the nature of his world.

During the past quarter century this power has not only become increasingly great but it has changed in character.The most alarming of all mans assaults upon the environment is the contaminatien of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable. In this now universal contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world, the very nature of its life.

It took hundreds of millions of years to produce the life that now inhabits the earth. Given time not in years but in millennia life adjusts, and a balance has been reached. But in the modern world there is no time.

It is not my contention that chemical insecticides must never be used. I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. I contend,furthermore, that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil, water, wildlife, and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.

Walk for children in poor areas

Not long ago, our school organized a charity walk to raise money for

children in poor areas.

It was on Saturday, 23 rd October. We walked from the school to the centre

of the city. Before the walk, we grouped ourselves into a team of four and

planned everything well. It was a hard (tough) work. But during the walk, we

supported and helped each other. With the help of many people, we raised over

(more than) 50,000 yuan in the end.

We all felt tired, but we were very happy. Because it was a meaningful

experience and it was an excellent chance to learn team spirit.

My View on Helping Others in Need

In modern society we are often sorry to see that people are reluctant to

help others out, not to mention helping a stranger; offering a helping hand

seems to be out of accord with the times.

Then what’s wrong with our society? Some people may say that facing

skyrocketinghousing prices, expensive medical expenditure and soaring commodity

prices, they have no choice but to struggle to make a living, and thus it would

be impossible to spare a hand to help others because it may bring them into

trouble. Therefore, standing by indifferently is their only choice.

However, is it necessary to be selfish in order to survive, or in order to

ensure that people do not take advantage of you? In my opinion, helping others

brings a strong sense of accomplishment. What’s more, the evaluation criteria

for judging one individual’s success should be modified so that offering a

helping hand to people in need is encouraged and welcomed in our society all the

time.

In the past few decades, our Earth has changed a lot, but to the bad

direction. Among these changes, the air pollutions resulting from a huge number

of automobiles and coal-burning is almost the severest. The severe air pollution

alarms humans of the heavy load we have exerted on Earth by our insatiable

production and usage of automobiles. However, with the deepening of

urbanization, more cars are needed, which will make the air pollution worse.

Therefore, the following actions should be taken. First, we should apply the

most cutting-edge technologies in order to adopt new forms of energy as

substitutes for fossil fuels. Second, try hard to develop possible

transportation means, which are enviromental friendly. So that the citizens can

reduce the dependence on cars. In short, our humans should take responsibilities

for the air pollution and have to find ways to solve this problem.

导语：随着网络的快速发展，网络舆论也带来了一些话题，下面是yuwenmi小编为大家整理的英语作文，欢迎阅读与借鉴，谢谢!

Do you still remember the “Guo Meimei Scandal” which has aroused national fury and mistrust toward Red Cross Society of China in 2011? However, it was just a start of the influence of network public opinion of China in changing the society. Now, nearly every day or two, there will be a new event heatedly commented by Chinese netizens through online facilities.

Actually, network public opinion is the co-product of the interaction between two factors. For one thing, the highly developed internet has brought the explosion of information to everybody’s life. Each piece of information can potentially be an “event”. For another thing, democratic consciousness has grown stronger in minds of Chinese people. Network is the democratic outlet where their free speech can be fully realized.

Now, network public opinion has become the constructive power for a better society, which has been acknowledged by all levels of governments. With overwhelming influence and massive power, it will help a lot in constructing Chinese social equity, including improving Chinese democracy, promoting anti-corruption; bring in judicial fairness, and etc.

实际上，网络舆论是两个因素之间的相互作用的共同产物。一方面，高度发达的互联网带来的信息爆炸，每个人的生活。每一条信息可能是一个“事件”。另一方面，民主意识在中国人民的心中成长。网络民主的出路何在他们的言论自由就可以完全实现。

现在，网络舆论已经成为一个更好的社会的建设性力量，已经得到了各级政府的承认。以压倒性的影响和巨大的权力，这将大大有助于构建中国社会公平，包括改善中国的民主，推进反腐倡廉;带来司法公正等。

Private cars have become an important aspect of people’s life in many parts of our country,especially in large cities such as Beijing,Shanghai and Guangzhou.While they bring much convenience to people,they are also widely criticized.

There are some arguments for owning private cars.In the first place,cars allow people to move around freely,whichgreatly improves our living standard.We easily drive cars for traveling.In second place,When we have something urgent to do,cars are quick than other vehicles in some extent.Last but not least,the car industry can boost economy by creating many job opportunities.

However,there are also many arguments against cars.First of all,they pollute the environment by emitting harmful gases.What’s more,cars cause a large number of traffic accidents,which bring great misery to their family.

As far as I am concerned,we should limit the number of private cars by providing better mass transportation and better service for the people.Everyone should sacrifice his or her own interest for the mass society.

Improve our environment

Good environment can make people feel happy. To improve the environment means to qualify our life . What should we do to improve our environment ?

We should plant more trees . And we should prevent those factories from pouring waste water into rivers , lakes and fields . Whenever we see litter on the ground , we should pick it up and throw it into a dustbin . Don’t spit in public places . Don’t draw on public walls . It’s our duty to keep our earth clean and tidy .

良好的环境能使人觉得愉快。改善环境，使我们的生活。我们应该做什么来改善我们的环境?

我们应该种更多的树。我们应该阻止那些工厂废水流入河流，湖泊和田野。每当我们看到地上的垃圾，我们应该把它捡起来扔到垃圾桶。不要在公共场所吐痰。不要在公共墙上画。这是我们的职责，保持地球的干净和整洁的。
