环境压力英语怎么说【20篇】

st important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

velopment and the Environment

It is undeniable that the worsening environment has become the biggest concern of the present-day world. Land resources are dwindling because of water loss and soil erosion. Waste gases poison the air we breathe. The rivers and lakes are polluted by waste dumped in them from factories. It is probably no exaggeration to say that deterioration of the quality of the environment threatens the existence of mankind itself.

Some people are of the opinion that the environmental problem is the price we have to pay for economic development. But I do not think that this argument is valid. After all, what is the point of economic growth if peoples lives are adversely alfected by worsening environmental pollution?

There is plenty of evidence to show that sustainable development can be achieved by balancing economic growth with protection of the environment. The key to achieving this is to make people aware of the seriousness of the problem. Both governments and ordinary citizens should join hands to make this world a better place to live in, not only for ourselves, but also for future generations.

Dear Uncle Huang，

Thank you for reading my e-mail! I am living in this community. I don’t have any sister or brothers. I also have no friends here. Luckily, you want to help us. Here are my suggestions.

First, we can organize the children in this community to clean up our neighborhood.

Our life will be fun and colourful.

Best wishes!

Yours truly,

Pressure seems to be a natural part in our daily life in this competitive

society. Like it or not there is always pressure of one kind or another. And it

seems there is hardly any way to avoid it or get rid of it. Moreover, as the

pace of modern life continues to quicken, pressure seems to be on the increase

all the time.

Different people have different ideas about pressure. Some hold that

pressure is something very vicious. If there is too much of it, it will lead to

the decline of ones physical and mental health. So they are always complaining

about it or trying to flee from it. They think, only relaxation, the opposite of

pressure, is what we should desire. On the other hand, others argue that

pressure is not as bad as is often thought. In fact a certain amount of pressure

is essential to provide motivation and meaning to our life. It is pressure that

propels our progress and contributes to our success.

Personally, Im in favor of the latter idea. I believe that a little

pressure is certainly an important incentive in life. It is only when the

pressure gets out of control can it lead to poor performance and bad health.

Since it is impossible to avoid pressure, certainly there is no sense trying to

do so or complaining about it.

In this picture a man rudely opens a garbage can and violently throws all kinds of waste into it. however, the box is not an ordinary trash can, but is, as a matter of fact, the earth. it is where survive, breed, and prosper. but as the drawing indicates, earth does not receive an equal repayment. quite the contrary, one of the biggest "gifts" humans return to earth is an unbelievable amount of trash.the picture purposefully points out a kind of pollution that arouses little public attention, that is, garbage. the past century has witnessed an unprecedented increase in garbage output, most of it technological products that are difficult to be decomposed through natural processes, such as plastics and glass. furthermore, a recent report released that several major chinese cities are already surrounded by circles of trash in the suburban areas, polluting air, water, and earth.

Hence, the issue of waste pollution needs to be addressed as one of the priorities that demand social efforts. only through a holistic system of trash disposal can this problem be fully solved. moreover, we should advocate a more frugal lifestyle so as to reduce the growing scale of waste pollution.

环境围绕我们身边，例如：空气、水、动物、建筑等。它们从各个方面影响着我们的生活，与我们的生活密切相关，人们离开环境就无法生存。每人每天都要呼吸、喝水和吃东西。我们少煤取暖、用木材造纸。结果，我们也成为环境的一部分。

很多年以来，环境日益恶化。我们在提高生活水平的同时，也在导致环境污染。从工厂烟囱里冒出来的烟污染空气；机器和引擎经常发出恼人的噪音。因为森林每分钟都在减少，使动物们无家可归。街道上挤满了人和车辆。环境在我们的生活中是最重要的，但是现在它已经让人们讨厌。所以，该是解决这些问题的时候了。

幸运的是，现在改正错误还不晚。人们意识到环境的重要性。我们已经开始尽力改善环境。法律也开始涉及到空气、水和噪音等问题。将来，河流会更清澈，天空会更晴朗，花朵会更鲜艳，阳光会更灿烂、更温暖。保护环境会使我们生活在一个更加美好的世界中。

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

与我们的生活水平的提高,越来越多的人都买得起汽车的。因此,道路往往没有堆满了汽车。然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重。所以现在我们提倡过低碳的生活。

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

The Importance of Trees

As we all know, trees are very useful. They are of great benefit to man as follows: First, trees provide us with wood and other products; Second, their roots can allow the rain to sink in and keep the soil, so they help to prevent droughts and floods. Trees can clean air and beautiful life.

Unfortunately, nowadays in many parts of the world lots of people fail to realize the importance of trees. They have cut trees down in large numbers without a plan,which makes the soil washed away. They dont know where there no trees, the rain washed away the surface of the soil and this causes floods.

We ought to plant trees each year and carefully look after new trees in order not to make the forest slowly disappear. Only in this way can we make the forest serve man forever.

树的重要性

众所周知，树有很多的用处，人类从中得到如下很多益处：第一，树给我们提供了木材和其他一些产品。第二，它们的根能让雨水渗进并保持乒壤以免被水冲走，所以树木可以预防旱灾和水灾。同时树木还帮我们净化空气，美化生活。

不幸的是，今天世界上很多地方人们没有意识到树木的重要性。他们无计划的大量砍伐树木，这样使得土壤被破坏，他们不知道那没有树的地方，一下雨就把土壤的表层冲走了，导致洪灾。

我们应该多植树，同时好好照顾小树，不要让森林一点点消失，只有这样才能让森林永远为人类服务。

Throughout the ages, the earth mother with the sweet milk fed numerous generations of descendants. The original she was decorated by the junior was very clear and moving. However, now human beings for their own interests, tortured her innocent and dark. Mankind has only one earth; and the earth is facing a severe environmental crisis. "Save the Earth" has become the strongest voice of the people of the world.

Humans are part of nature and are part of the world of life. Many lives constitute a coexistence and coexistence related to the reputation of large systems. Humans must treat nature, care for the environment, protect animals and plants, otherwise, will endanger their own survival.

Once upon a time, people have been cut off, so that the ecological balance of nature has been destroyed. Dune swallowed the vast expanse of fertile land, the flood washed away the lovely home, the natural revenge of human embarrassment dumb. Mei Shui River once said that there is no natural, there is no human, this is the world a simple truth. Blindly plunder nature, conquer nature, will only destroy the ecosystem, blame themselves, so that human beings on the verge of difficulties. This sentence is not bad, people do not give natural face, of course, naturally will not give people behind the road, 98 floods, dust storms in 2000, 08 earthquake, in fact, this is the nature of the warning issued to mankind. Environmental protection is not a new problem for us, and our government has long put forward clear governance objectives. As a real life in every ordinary people, although it is impossible to directly engage in environmental protection work, but we can start from small, start from me. We should establish environmental awareness and take practical action to implement environmental action. See the faucet in the toilet when the drip should be able to raise their hands. When the battery is used up after the collection should be collected instead of readily throw away. When shopping should consciously do not use ultra-thin plastic bags ... ... a small thing though very humble, but it shows how much we have a sense of environmental protection.

Cherish resources, protect the environment. Lets make this city more beautiful!

Remember, protect the earth is to protect yourself!

What I expect for city life is not just about drink bars, shopping mall, entertainment center etc, although they are indeed better than the facility in the rural areas. What I expect for city life is a clearer environment, not only in the surroundings but also in peoples spirit. I hope the people around me are all good mannered with politeness and courtesy, there is no quarrel, no battle, people treat each other with respect. I hope there would be no traffic jam as in Beijing our country capital today where traffic jam happened everyday, which make the citizens feel depressed and great pressure.

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。

I have had a dream, in the dream I dreamed that the qingshui river became very terrible.

I went to qingshui river with my father and mother. I was just walking towards the river when I heard a loud crying. I followed the sound of the past, it was a piece of grass. I squatted down and asked, "grass, why are you crying here?" The grass said, "this is a vast prairie, but people are going to build a big house here. My sisters have been pulled out, and I am the only one who has not been pulled out." "Said the grass, and began to cry again.

I stood up, turned and heard: "help me." I walked past, originally is qingshui river to cry. "Why are you crying?" I asked curiously. "Please help me," he said. I saw an aunt throw a pack of garbage into the water. Plastic bags fly apart in the air, wrapped in peel, the leftover soup is scattered into the river. I went over and said, "aunt, its wrong of you to do so." The aunt said angrily: "you care for me? Little thing. You see, everybody is not like this?" I looked across the river and some of the people on the bank had coal dust, some threw waste paper. Some factories are discharging black and black waste water, along the river, into the distance. Then I saw a yellow and yellow thing floating on the river.

God, thats terrible!

Wake up and think of the old water river. In the summer some people play in the river, and some fish swim freely in the water. On the bank of the river, the willows fly, and the bees sing.

From now on, we will save water, protect the environment and protect our homeland. My slogan is "protect the environment from me."

导语：近年来,环境保护仍存在许多问题。其中最严重的问题之一是空气、水和土壤的严重污染。下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

【参考译文】

近年来,环境保护仍存在许多问题。其中最严重的问题之一是空气、水和土壤的严重污染。污染的空气对人体健康有害。污染的水导致疾病和死亡。此外,随着现代城市的快速发展,植被已大大减少。

为了保护环境,许多国家的政府做了很多。已采取立法步骤控制空气污染,保护森林和海洋资源,制止任何环境污染。因此,政府在今天的环境保护中发挥着最重要的作用。

我认为,要保护环境,政府必须采取更具体的措施。首先,它应该让人们通过教育充分认识到环境保护的重要性。第二,应该更加努力使人口规划政策付诸实践,因为更多的人意味着更多的人意味着更多的污染。最后,故意破坏环境的人应该受到严惩。我们应该让他们知道破坏环境意味着毁灭人类自己。

Today I saw an article called "everybody comes to the bend". The message is that the students will work together to protect the schools environmental health.

The environmental health of our school is not good enough. Although many students love the school very much, every day you can see many students in earnest service for schools, some pick up the garbage in the trash on the ground, some active hand at the broom sweeping the floor, and take the initiative to clean the blackboard......

But also some students could have done better in cleaning, including me, sometimes very throw rubbish casually, confetti, some classmates clearly see the floor with paper scraps, but them as invisible, this is not "ownership" of the spirit, also greatly affect the appearance of the school. Hope the students to act, "everyone to curved waist" activities, all be the master of the school, everyone starts from me, for us to make our campus environment clean and beautiful. Let people study in high quality environment so that they can get good grades.

今天我看到一篇文章名为《大家都来弯弯腰》。内容是讲，号召同学们齐心保护学校环境卫生。

联想到我们学校的环境卫生也做的不够好。虽然许多同学都非常爱学校，每天可以看到许多同学在认真地为学校服务，有的捡起地上垃圾扔在垃圾桶，有的主动拿起扫帚扫地，还有的主动擦黑板......

可是还有些同学在保洁方面做得不够好，包括我自己，有时很随便地扔垃圾、纸屑，有的同学明明看到地上有纸屑，但他们当作看不见，这样很没“主人翁”的精神，也大大地影响了学校的面貌。希望同学们行动起来，开展“大家都来弯弯腰”的活动，人人争做学校的小主人，人人从我做起，使我们的校园环境既清洁，又美丽。让大家在优质的环境中读书，这样才会取得好成绩。

英语作文汽车环境污染二

Too many cars have caused a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. Thus, the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

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。

Road on both sides of the border, the green pine, green holly, in the cold wind sway.

这时，一位叔叔正要把抽完的烟蒂扔向花坛，我急忙赶过去说："叔叔，请爱护环境，不要随地乱扔烟蒂。"

At this time, an uncle was about to finish the cigarette butts into flower beds, I hurried over to say: "uncle, please take good care of the environment, do not throw cigarette butts. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

叔叔看着我不好意思地笑了，说："对不起，小朋友。"说完，他主动把烟蒂掐灭，送到垃圾箱里。

Uncle looked at me and smiled sheepishly and said: "Im sorry, kids. "Finished, he took the initiative to put out cigarette butts, sent to the dustbin.

我高兴地说："谢谢你，叔叔。"

I am happy to say: "thank you, uncle. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

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.

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。
