学校环境问题英语作文合集2篇 作文怎么写【汇集20篇】

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 bee 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

are

still 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。

Now, "environmental protection" has become a global focus. But to truly protect the environment, we must start from ourselves and start with the small things around us.

One day, I went to play in the small river in the park. A little boy wanted to throw a fresh bottle into the river. I looked at it and said, "no matter what, Im going to play. If I take care of him, I wont be able to play." But at this time, one is old man on a fishing trip saw the little boys behavior quickly held out his hand to stop a small boy, and said to the boy: "child, dont throw rubbish into the river." The little boy listened and put down the bottle and said to the old man, "whats the big deal? Besides, this is a bottle, not a garbage." The old man listened and was not angry. Smiled and said to the boy, "son, you dont understand. You dont see it as a bottle, but it will also be like other garbage pollution water. We cant drink clean water. Moreover, the trash can is over there, a few steps away." The little boy was speechless to the old man. He said "thank you" to the old man and ran to the trash can.

I listened to that thought, "thats right. When we want to throw fruit peel, tend to throw the rubbish casually into the trash can outside, and ignored. In fact, as long as you stretch out his hand, will be thrown into the trash can. Sometimes, you can throw some wrapping paper with a, then a walk it. Later, you said cant find the trash can. In fact, trash can in a few steps away." These little things can reflect a persons moral character and whether he loves the environment around him.

Protect the environment. Its all about us. Everyone has to do their part. This will make our home more colorful!

Because of the fiction movie 2012 which describes a horrible scene that the whole world was destroyed by earthquake, volcano and tsunami, the view of doomsday is making a great clamor. Mayans predicted December 21, 2012 is the end of the world and the sun of 22th will never rise again.

Though it is now seems that this prediction is just a nonsense without any scientific support, it did provoke peoples thinking about environment. In awake of the prediction, we cant help asking why this horrible prediction happen? I think one answer may be related to the environmental degradation. As we all can see and feel, the worlds environment is going downhill with severely polluted rivers and airs. More often we cant see clearly the sun because of heavy air suspended matter caused by pollution. If continues going this way, I think the doomed day will come true if not now, then one day.

In consequences, for the sake of our own life, we should take efforts to protect the environment and save this planet. is the alarm bell to human beings that we should protect our planet, culture and civilization. Otherwise, the doomsday will come soon.

[英语CET-4作文：末日论引发的环境危机

转眼间，刚刚还是少先队员的我，已经步入中学大门，开始一段新的学习生活。

进入校园内，教学楼前有两片绿地，绿的十分显眼，如果眼睛累了，或许还可以从教学楼内看看，可以使人神清气爽，让眼睛得到休息。

走进校园，到处种着花花草草.一阵风吹来，花花草草跳起了“迎新舞会”.看！其中的一朵，正在对着我“笑”呢！校园内的路道旁，种着一棵棵高大的树.它们是士兵！保护着我们，度过一个个春夏秋冬！小花，小草以及大树，无不洋溢这青春、自由的气息！巍峨教学楼，穿有一件红色的外衣，上面还缀有几条白色丝带，缝有黑色花边。它的红色，正如一轮初生的红日，朝气蓬勃，欣欣向荣。顿时，给我一种带有激情力量的动力。

黑发不知勤学早，白首方悔读书迟。我要和美丽的校园一同相伴三年，一同成长，奋斗。我喜欢新的校训，这新的校训能感受到浓浓的书香。我要努力学习。

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.

Green water show in the future there is a mountain city, the mountain forests, lush; A stream of water on the bottom; Air pure and fresh and sweet. Industries where there is no smoke, no river floating in a plastic bag, without being cut down trees, only a piece of green.

In the future, humans and animals and plants live in peace, a shotgun into each bird, chainsaw into hits the thick, strong, tall and straight trees, the atomic bomb in the museum, and pulled down the factory chimney, spread a far-reaching blue sky... Then have no the word "cage" in the world, it is full of human and animal for a walk, play games together. To do this, human also built a school to educate minors, animal, building on the twelve golden characters: the "people live in harmony, to build better homes!"

However, the future may also be another scene like: neat rows of factory was built on the hillside, its discharge smoke originally cbsi cbsi pollution became gray sky. The river became smelly, dark, light, cutting down the trees bare stumps, there are many, white plastic bags. Many years later, a sandstorm thoroughly changed all that, that day, dust storm flood came, the whole world of darkness covert, dust storms have been shaved nine days nine nights, all the cities, factories are all turned into desert, everything vanished.

Kid, the above two kinds of the future city which one do you want to let the world become? If you want the first kind, is to protect the environment, come on!

在未来有一个山青水秀的城市，山上的森林郁郁葱葱;小溪的河水清澈见底;空气清新甜润。那里没有工厂排出的浓烟，没有河上漂浮的塑料袋，没有被砍伐的树木，只有一片的绿色。

在未来，人类与动植物和平相处，猎枪变成了一只只的小鸟，电锯变成了一棵棵粗壮、结实、挺拔的大树，原子弹在博物馆展出，而工厂的烟囱被拆掉，铺成了湛蓝深远的天空……那时世界上已经没有了“笼子”这个词，处处可见人类和动物一起散步、做游戏的场景。为此，人类还建了一所学校来培养未成年人、动物，教学楼上闪着十二个金灿灿的大字：“大家和谐相处，共建美好家园!”

然而，未来也可能是另外一种景像：一排排的工厂整齐的被建在山坡上，它排出的浓烟把原本瓦蓝瓦蓝的天空污染成了灰色。河水变得臭了、黑了，树木被砍光了，裸露的树桩上有许多的、白色的塑料袋。许多年以后，一场沙尘暴彻底改变了这一切，那一天，沙尘暴铺天盖地地袭来，整个世界昏天暗地，沙尘暴一直刮了九天九夜，所有的城市、工厂全变成了沙漠，一切都消失了。

小朋友，以上两种未来城市你想让世界变成哪一种呢?如果想要第一种，就赶快保护环境，行动起来吧!

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.

World Environment Day was established by the United Nations General Assembly in 1972 to mark the opening of the Stockholm Conference on the Human Environment. Another resolution, adopted by the General Assembly the same day, led to the creation of UNEP .

World Environment Day can be celebrated in many ways, including street rallies, bicycles parades, green concerts, essay and poster competitions in schools, tree planting, recycling efforts, clean-up campaigns and much more.

Heads of State, Prime Ministers and Ministers of Environment deliver statements and commit themselves to care for the Earth. More serious pledges are made which lead to the establishment of permanent governmental structures dealing with environmental management and economic planning. This observance also provides an opportunity to sign or ratify international environmental conventions.

World Environment Day, commemorated each year on 5 June is one of the principal vehicles through which the United Nations stimulates worldwide awareness of the environment and enhances political attention and action.

The World Environment Day theme selected for 2004 is Wanted! Seas and Oceans - Dead or Alive? The theme asks that we make a choice as to how we want to treat the Earths seas and oceans. It also calls on each and every one of us to act. Do we want to keep seas and oceans healthy and alive or polluted and dead?

The main international celebrations of the World Environment Day 2004 will be held in Barcelona, Spain in close collaboration with the Universal Forum of Cultures. UNEP is honoured that the City of Barcelona, the Catalan Regional Government and the Government of Spain will be hosting this important United Nations day.

世界环境日成立于1972年由联合国大会开幕纪念斯德哥尔摩人类环境会议。另一个决议,联合国大会通过的同一天,导致联合国环境规划署的创建。

庆祝世界环境日可以在许多方面,包括街头集会,自行车游行、绿色音乐会、论文和海报比赛在学校、植树、回收工作,清理活动等等。

国家元首、总理和部长环境提供声明和承诺照顾地球。更严重的承诺是导致建立永久性政府结构处理环境管理和经济规划。这个仪式也提供了一个机会签署或批准的国际环境公约。

6月5日世界环境日,每年纪念的主要车辆通过联合国促进全球环境意识和提高政治关注和行动。

2004年世界环境日的主题选择想要的!海洋和海洋——死的还是活的?主题要求我们做出选择,我们要怎样对待地球的海洋和海洋。它还要求我们每一个人采取行动。我们想要保持海洋和海洋健康和活着的或污染和死了吗?

的主要国际庆祝世界环境日2004将在巴塞罗那举行,西班牙与环球论坛密切协作的文化。联合国环境规划署是巴塞罗那市的荣誉,西班牙的加泰罗尼亚地区政府和政府将主持这一重要的联合国日。

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。

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.

Secondary school students as our primary task is to do a good job learning that is the protection of the environment on the basis of the knowledge you learn in their own minds, they can form a sense of environmental protection only do you have about your sense of action in order to have the idea then you have to do our best to influence People around to learn about the environment to understand the importance of environmental protection and you will make every effort to persuade friends and family and You fight side by side together to protect our common Earth

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.

现在起，我们应该保护环境，一起捍卫我们的家园。

Now, we should Protect environment, to defend our homeland.

尊敬的市长先生：

您好！

我是本市第二十八中初二的一名学生，我从小在南昌市长大。这几年，南昌市的高楼如同雨后春笋般出现，从一个普通的小城市渐渐地发达起来，变得繁华起来。

最近几年来，南昌市正在修建地铁，很多的路面上都坑坑洼洼。我的学校边上也正在修建地铁，很多时候都会有满天的灰尘吹进我们的教室，所以有灰尘的时候我们基本不开窗，但是这也污染了我们这座城市的空气……

不过话说回来，我也支持建地铁，因为这方便了我们今后的交通，所以修建地铁也是一件好事！

我每天早上都会经过滕王阁旁的抚河桥，抚河以往是很清澈的，可是不知道为什么，近期抚河的水开始变得浑浊不清，河面上总是漂浮着白色垃圾，到了夏天，河面上甚至会出现死鱼，发出一阵阵臭味。

现在人们的生活条件也好了起来，家家户户都有汽车，虽然这并不算什么坏事，但是如果每天都有这么多车开出去，该造成多大的空间污染啊！

在公园和一些闹市区，总是可以看见许多老人家带着自家的小猫小狗出来溜达，虽然这没什么大碍，但是宠物的主人大多数都不会去收拾自家宠物的排泄物，就让它臭气熏天地在路上，而且许多人也习惯性地将垃圾随手一扔，扔的人多了，垃圾也就越来越多，风一吹，垃圾就满天飞。

所以，市长叔叔，为了让南昌市的居民有更好的环境，我想提一些建议：

1、限制每户买汽车的辆数，超过了就必须纳税，这样一来，便可以很好的控制汽车的数量，每天排放的尾气就减少了很多。

2、应在河上投放垃圾打捞船，这样就方便了打捞水中垃圾的工人处理垃圾。这样河水又能恢复美丽的容颜了。

3、多找一些志愿者在公园或其他场所进行监督，对乱扔垃圾的市民进行劝阻。

以上就是我的建议，如有不妥的地方，请您多多包涵，如有好的建议，希望您采纳！

此致

敬礼！

20XX年XX月XX日

我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。以下是小编给大家整理的形势与政策论文：城市水环境的问题探讨的内容，欢迎大家查看。

摘要: 随着经济快速发展，城市生态形势压力也与日俱增，水环境问题已成为制约社会发展的大问题，环保基础设施建设严重落后，城市生活污染物未得到有效控制，工业污染源未得到严格治理，农业污染日益突出，部分河段水质受污染严重，河水发黑发臭，完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词：城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分，城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响，我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失，造成了城市生态环境、水环境的进一步恶化。针对这样的情况，我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发，恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型，由于城市人员密集、工业化生产程度高，所以，城市用水需要较高的质量、较大的供水量、稳定的供给，这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高，所以，单纯依靠城市区域的供给和开采往往难于满足城市发展的需要，因此，大众城市往往需要从城区周边或外地调水来满足城市的用水需要，“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方，城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中，在日积月累的大量污染的影响下，城市水环境受到了严重破坏，并且这一现象有蔓延和恶化的趋势，造成水环境的脆弱和生态的破坏，影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个，一是，城市生产和生活中大量污染源渗入地下，造成对地下水资源和水环境的破坏;二是，城市地表硬化导致城市地面下渗量的减少，在大量开采地下水的同时，没有必要的补充，出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本，科学发展

把维护广大人民群众的根本利益作为第一点，把群众最关心、最直接和现实的水环境保护问题为重点，转变发展观念，重视生态文明建设，加快建设资源节约和环境友好社会，走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品，水环境治理应突出重点，优先保护饮用水源，确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩，把COD削减量考核指标纳入到区县水环境治理目标体系中，明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标，即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金，对节能减排效果明显，有一定经济基础，技术条件成熟，符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集，污染来源复杂。为此，河道治理将坚持“先截污、后清淤、先治理、后换水”的原则，周密排查河道沿线污染来源，大力实施清淤、截污、生态护坡、河岸绿化等措施，加强河道水体自净和生态修复功能;在突出截污治理的同时，各区县还将坚持污水处理厂、配套管网同步建设，大力提升现有污水处理厂运行负荷率，妥善解决污水出路，切实提高河道水环境质量。

5、加强协作，落实责任

市水务局于去年成立了河道水环境考核办公室，将清水工程已治理河道纳入考核范围，各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制，有效巩固水环境治理成果。此外，目前市政府已正式批准本市河道水环境实施“河长制”管理意见，即将公布全市主要河道“河长”名单，构建完善的河道水环境管理长效机制，为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述，我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。

保护环境的英语作文一：

Topic:

Environmental problems are as big as not for individual country or individual people to address。 In other word， we have reached the stage that environmental problems be solved for international view。 To what extent do you agree or disagree?

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。 The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

环境问题 英语作文【1】

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.

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.

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?

Recently,fog and haze has become a imminent threat which most northerners in China are facing.

While the cities of China have greeted striking speed of development with open arms,they suffer greatly from a persistent and dense haze of pollution and smog.

It is high time that we took some methods to protect the environment and ourselves.

Generally speaking,there are three effective ways.

First of all,the government should take into serious consideration the emergency and severity of the air pollution,and take measure to deal with it.

Such as more public transportation systems should be put in use,more energy-saving resources should be utilized.

What’s more,every little effort from individuals counts.

The citizens should contribute to the reduction of pollution by driving less.

Last but not least,try to reduce the time of outdoor activities,especially when the air quality is not good enough.

From what has been mentioned above, to protect our air,we must keep in mind that whatever we give out,we take back in the long run.

So we have to drive less,pollute less and make more changes.

Stepping into the new century, environment pollution has become more serious than ever since. There are different kinds of pollution. Such as, water pollution, air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. Where all these pollution comes from? To a large extend, the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel, people cut down trees and dig more corals. But the growing needs for energy are hardly to meet. Countless private cars on the street, the gas stations are short of gasoline, even the government has raise the price so many times in order to control the needs of gasoline, but it’s still not working. Overusing the natural resources has already affected the ecological balance. However, the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.

The government should put forward some more strict laws to prevent the environment from being further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again. Only in this way, our earth could be a better place to live in.

进入新世界以来，环境污染比任何时候都要严峻。有各式各样的污染：水污染，空气污染，噪音污染等等。看起来我们活着一个四周都是污染源的星球。那么，这些污染是从何而来的呢?在很大程度上，环境被破坏就是我们为快速的经济增长和人口增加所付出的惨烈代价。为了得到更多的能源，人们砍伐树木，挖更多的煤矿，但是还是难以维持日益增长的需求。不计其数的私家车充斥着公路，加油站的汽油严重短缺，政府多次上调油价也未能阻止私家车对汽油的需求。自然资源的过度利用已经影响到了生态平衡。然而，工厂依旧向外排放有毒气体，把工业废水倒入河里。人们依旧缺乏保护环境的意识。我认为人们应该做些事情了。

政府应该施行一些更为严格的法律来防止环境被进一步的破坏掉。他们应该让人们了解到保护环境的重要性。我们要在保持经济发展和环境保护中找到平衡点。在沙漠中植树造林，停止砍伐森林。禁止工厂往河流里直接排放废水。鼓励人们用交通工具上班。政府和普通民众都应该携手保护环境，让我们的家园变得干净整洁。只有这样，我们的地球才能更适合人类居住。

走进校园，中间是中学楼，两侧是食堂和小学楼。走进食堂一层，啊，好宽敞好大啊，桌椅摆得真整齐，我们再也不愁没饭吃了。食堂还有卖零零食和文具的地方。这时，走来了一位学生，在买饭口点了自己爱吃的饭菜，用饭卡在刷卡机上一刷就付钱了，啊，真方便。

The concept of responsibility is a necessary fiction. Although socities must hold their individuals accountable for their own actions, people‘s behavior is largely determined by forces not of their own making.

In the title statement, the speaker holds the contention that the concept of ‘individual responsibility‘ is no existence but a fiction. Moreover, the speaker says that the behaviors of human beings are fundamentally determined by the environment which out of their control. Admittedly, one‘s actions are deeply influenced by laws, societies, schools and families and other exterior forces; individual responsibility exists and functions as a significant role to rule people‘s behaviors as well.

On one hand, the highest social animal as human being is, any individual has his specific role in a certain society. And this specific role gives one social identity and individual responsibility through education in schools and influence of ethical and moral standards. Though some times one would feel that the certain responsibility is obligation from the society and organizations rather than his ‘individual responsibility‘ at first, in most cases, the accountability would presumably become one‘s own eventually followed by the final identification of his specific social identity, and then direct one‘s behaviors without the force from the exterior world. For example, a soldier would think it is his duty to obey the rules without any hesitation; a surgeon would consider healing the patients as his accountability; and a historian would feel it is his responsibility to discover what is behind the historical descriptions. In fact, different careers and roles form diverse individual responsibilities, which result in individuals’voluntary behaviors.

On the other hand, there are not only specific individual responsibilities in diverse areas but also some fundamental values and accountabilities, which we all human beings cherish. From the moment one can speak or even is born, the society begins to instill the moral and ethical standards, which is so called humanity in every one‘s mind. The older one is, the deeper influence the humanity would be. When one is just a little child, he would go directly to what he like and claim it. Then when he is old enough, he would realize that it is incorrect and ashamed. And because of the awareness of what is right and wrong, one would probably never do any misdeed again. Actually, humanity is just the common individual responsibility shared by all of us.

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.

However, every one lives in a certain society thereby one‘s behavior is more or less influenced by forces not of their own making. And to operate normally, every society has its laws, though many times have differences among them. It is true that humanity plays an essential role in ruling individuals‘ behaviors; yet laws are necessary. Under the control of laws, people who have little individual responsibility would probably not dare to do any crime in fear of law punishment. Besides laws, for example in school, rules are also an important factor as well as individual responsibility. Nowadays, in most universities, a student who does not pass some certain courses in his four years college life would not get his diploma of bachelor‘s degree. So even if a student does not like his discipline, or dose not care about his GPA, the pressure of graduating forces him not to playing computer or basketball all the time.

In addition, individual responsibility and forces from outside world have overlapped parts some times. For instance, studying diligently is some hard- working students‘ individual responsibility as well as the pressure from schools and society.

Generally speaking, it is hasty and incorrect to conclude that the concept of ‘individual responsibility‘ is a necessary fiction. On the contrary, individual responsibility plays an important role which cannot be replaced. However, laws and the exterior force also have their significance as well. Thus we can not put either of them aside and pay more attention to another.

Water is a kind of liquid. It has no taste or smell. It is transparent, too. Water is useful and is important to us. Why? For example, we use water to water the plants. We use water to wash our face or to have a bath. We drink water or we will die…Water is also very important for China. There are 2.8 hundred millions of steres of water in China, but everyone can only use 2300 steres. It is only twenty–five per sent in the world.

Not too long ago, there was a man called Jacques Cousteau. He loved the beautiful colors, and the beautiful fish in the sea. However, when he returned some years later, the colorful coral reefs were dead and grey because the factory near the sea poured waste water into the sea. Jacques Cousteau decided to tell people how important it was to save the environment under the sea. He started the“ Cousteau Society ” to help protect life in the sea. Now there are over 30000 members all over the world. Since water covers most of the earth, Cousteau knew that we should keep the sea clean. We should not litter the sea, and should clean up the dirty parts. As water is very important to our environment, he encouraged everyone to take part in protecting our lakes, rivers, sea and ocean.

There are still a few people who are not protecting the water now in the world. For example, some factories pour waste things into the rivers, lakes or into the sea near by. The water there has become very dirty and we can’t use them at all. Although there are seventy–five per sent of water in the world, we can only use fresh water, that there is only a little. So we should use little water when we need to use it. For example, I do not use too much water when I am washing my face or having a bath… It is important for us to keep the water clean. You may ask yourself, have I ever poured or thrown dirty things into the water? If your answer is “No”, that means you have already helped to protect the environment. It is our duty to protect the environment. You may ask yourself again, have I ever helped to clean up the water? If your answer is “Yes”, that means that you have already done something useful to improve the water. If we use up all the water, it is difficult for us to get it from anywhere, including the universe. It is terrible to think that people are too thirsty to live! I believe, that if everyone helps to protect the water, the water must be protected. You do not want to “kill” your son or your grandson, do you? So now let us to protect the water! Please don’t let the last drop of water on the earth is we human’s tear!
