有关空气污染英语作文(热门20篇)

空气污染是空气中某些物质的含量超过正常含量时，形成危害动、植物，影响其生存的现象。大气中C0、NH3、SO2、H2S、Cl2、03和N02等物质的正常含量均在百万分之一以下，对动、植物没有明显的不良影响。但19世纪以来，由于工业和交通运输的发展，那些物质大量排入大气，使空气污染日趋严重，影响到动、植物生命活动乃至人体健康。

污染物的来源，有的来自自然界（如火山喷出的烟灰），有的来自人类活动，其中工业、交通运输产生的废气是主要的污染源。空气污染可分为气体污染物和气溶胶状污染物两大类。气体污染物包括SO2，、03，、氮的氧化物以及碳氢化合物等；气溶胶污染物包括固体粒子（粉尘、烟尘气）和液体粒子（烟雾、雾气）两类。直接向空气中排放的污染物质，叫一次污染物。空气与污染物之间相互作用，产生反应，或空气中光化学反应引起的污染物变质所产生的新污染物，叫二次染物。

空气污染物种类很多，其中对农业威胁较大的约有十多种，如SO2、 HF、C12和光化学烟雾等。 气象条件对空气污染物的影响，水平风速和对流层高度是影响大气稀释空气污染物能力的两个气象要素。当农田上空主导风向来自污染源时，农田容易受有害气体的危害；风力强弱则影响空气污染物的扩散速度、污染物在空气中的浓度与平均风速成反比；通常午后湍流强，空气处于不稳定状态时，有利于扩散。夜间晴朗无风，近地面逆温层可使污染物在地面上停滞积聚，加剧空气污染的程度。另外，在准静止的高气压系统中，由于下沉逆温阻止下层排放的污染物扩散到大气上层，可形成近几百米厚的污染层。各国多次发生的严重空气污染事件大都是在低逆温层、风速小和无雨的气象条件出现几天之后形成的。

空气中一些污染物例，如SO2和悬浮于空气中的农药颗粒等，经雨水淋溶落到地面，又可污染土壤和植株。污染物对植物的危害，一般是通过气孔进入植物组织，干扰酶的作用，阻碍代谢机能，有的有毒物质在体内还可进一步分解或参与合成过程，产生新的有害物质，侵害细胞组织，抑制光合作用，使生长受阻、产量降低、品质变劣。其危害分为急性、慢性和不可见危害等。高浓度污染物造成急性伤害，引起产量显著下降，低浓度污染物，在长时间作用下，造成慢性危害，一般症状不明显。不可见危害只造成生理上的障碍，一般没有症状。

植物受空气污染危害的程度，主要受下列因素影响：污染物浓度和植物接触它的时间；植物本身的构造和所处的发育期以及环境条件的影响。如充足的光照，适宜的温度、良好的供水和空气湿润，较高的C02浓度等，都能导致叶片气孔开放，易受污染危害。 植物对大气的净化功能。不少植物具有一种以酶作催化剂的潜在解毒力，能够分解一些有毒物质，或形成一些大分子络合物，暂时可以降低毒性。1公顷森林，每年可吸滞灰尘30多吨，1公顷柳杉林，每年可吸收700多公斤S02，柑桔树的叶子可吸收储存硫达1％，青杨和桑树具有较强的吸收铅尘的能力，加拿大杨、银杏、榆树、梧桐、桉树等都是较好的“天然吸尘器”。草坪的吸附粉尘能力比裸露地面大几十倍。因此环境科学的任务之一，是要充分发挥植物净化大气的作用。选择吸收污染能力强的植物，扩大造林绿化面积，根据污染源位置、污染物汇集区的地形地势、风向和污染气体的季节分配，统一考虑构成一种包围式或隔离式的林带，使含尘气流在移动中途被树林吸收。另方面要研究采取控制或减少排放污染物的措施，以保证大气质量符合规定的标准。

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.

Nowadays, a lot of environment has been seriously polluted. Now, look at the polluted environment.

The river

I was walking in the park, smell a smelly fish, the pedestrians on the road also cover your nose in one hand, with his other hand fan with bad smell, I cant stand, hurriedly to speed up the pace, I looked down and turned out to be a lot of dead fish in the river, is this why?

Looking at the already clear water of the river is now dark, the original lively and disorderly fish are also motionless, I have a feeling of not coming out!

air

It is a sunny day, I a person walking in the street, the road cars, buses, motorcycles, the horn is to me a son to chung, car and more up, however, pedestrians less, because the way the air became more pungent, car tail industrial waste gas, contain a variety of toxic substances, in the sunshine, will produce many harmful gases, respiratory tract have a lot of harm to human body, high incidence of respiratory disease. Why do people have bicycles? It is one of the best tools for overcoming heart disease, and cycling can also help prevent high blood pressure, sometimes more than medicine, and can prevent weight gain, hardening of the arteries and keeping the bones in half. And bikes dont emit waste gas and are healthy. Doesnt this kill two birds with one stone? So I urge people not to drive a bike only, for the whole earth more color, one less dirty!

Here, I appeal to everyone to love our home -- earth, we have only one earth, you do not love her how do she love you? So let us work together to make our home more beautiful and rich. And everyone thrifty, polite and hygienic, so that the whole earth will be more beautiful and clean! I believe that after listening to my appeal, we will all act together to make our family more beautiful, wont we?

周六上午，我和爸爸妈妈一起骑车感受一下濮阳市的空气质量。虽然天气寒冷，但我也感觉不到冷，因为我要做一次小小的空气调查员。

一路上我们有说有笑，当走到黄河路西段时，一股难闻的气味扑鼻而来。我便问爸爸：“爸爸，这是什么气味呀，这么臭。”爸爸对我们说：“这里是我市的化工厂区，化工厂产生的废气气味。”

爸爸妈妈又带我来到马夹河边，看到河水的颜色发黑，并有一阵阵的恶臭，我问爸爸：这是为什么呢?爸爸给我讲：这是因为化工厂的污水和家庭的废水排向河流的缘故。

现在的空气污染太严重了，化工厂产生的废气，家庭的废水不经过处理直接排向空中和河流，汽车、摩托车等机动车数量迅速增加，尾气排放量加大。由此造成严重的空气污染。

为了缓解空气污染，请大家从身边的小事做起，不要乱扔垃圾，不要在野外烧火，尽量不要用尾气排放量高的汽车……相信有了大家的支持，空气污染造成的危害一定会消失!

It is very important to deal with the rubbish in cities. Rubbish must be thrown away or reused properly. Or it may cause a lot of problems. It may pollute the air and water. People may get ill when they breathe the polluted air or drink the polluted water.

Our city has started to face the problem. Some rubbish is sorted and sent to a certain place .Waste gas is cleaned before it goes into the air. Waste water is also cleaned before it is poured into rivers.

People should be prevented from throwing rubbish everywhere. We should try our best to take care of our environment and fight against pollution六年级英语环保作文：Saving Our City.

我的家乡——焦作，以前是一个风景如画的地方。

一天，我和妈妈去散步，我看见了一个大x囱，上面冒出了黑烟，像一条大黑龙冲上天空，它们张牙舞爪，顷刻间把蓝蓝的天空覆盖了，天变的灰蒙蒙的，把白云吞噬了，就连太阳也被它吓跑了。

看到这一切，我伤心极了。这些烟雾中，有着大量的烟雾，吸入眼睛里，会导致眼睛发红，发涩，吸入呼吸道里，会发生支气管炎，严重的还会导致死亡。

我们应该少开车，多走路，如果要去的地方很远，那也不要开，做公交车就行了，也要把那些化工厂搬到离城市比较远的地方去，这样子就不会污染环境了，对人类的危害就会少些。

我希望天会更蓝，水会更清，草会更绿，花会更红，相信经过大家的努力，人类的生活会更美好。

With the remarkable improvement of peoples living standard, people tend to buy more goods. As a result, a plenty of plastic bags are threw around and caused white pollution. Not only does it do harm to the environment, but also give people the impression that the city is dirty. As we all known, plastic bags are non-biodegradable material and it will stay in the soil for a long time. What’s worse, the poison released from the plastic bags is harmful.

随着人民生活水平的显著提高，人们购买的商品越来越多。所以，到处都是塑料袋，造成白色污染。塑料袋不仅污染环境，也给人城市很脏的印象。众所周知，塑料袋是不可生物降解的材料，会长期留在土壤里面。更糟糕的是，从塑料袋中释放的有毒物质是有害的。

Being current generation of young people, we should take measures to control the use of plastic bags .We can substitute them with cloth bags or reuse them. And the government can make rules to avoid using them. If we do our best, the use of plastic bags can be reduced, thus the white pollution can be controlled.

作为当代年轻的一代，我们应该采取措施来控制塑料袋的使用。我们可以用布袋来替代塑料袋或者重复使用。政府也可以制定规定来避免使用塑料袋。如果我们努力做好，塑料袋的使用就可以减少了，从而白色污染也会得到控制。

Although some citys air quality is improving, but it is estimated that the number of deaths due to air pollution each year up to 358000 people.[5] according to the self assessment, air quality in the recorded data of 338 cities, two-thirds is considered contaminated, two-thirds of which was rated as moderate or severe pollution.Related to air pollution in China, breathing and heart disease is the top killer.Thirty percent for acid rain place.The Chinese governments environmental regulations are thought to have 20 years behind the United States, 20 to 30 yearsbehind that in Europe.And because of car usage increases, a true problem isworsening.

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。

harmony with the environment is that we live in on earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and the mountains on earth. .harmony with the environment is that we live in on earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and the mountains on earth, the animals. plant human cells, if it damaged, destroyed nature organizations, to the eradication of mankind. therefore, the environment must be linked with social ethics, character education and practice acts as an important element of it. everyone must fulfil its responsibilities and obligations to protect the environment

人与环境是和谐相处的,我们生存在地球上,人是自然之子,而不能仅把人看作自然的征服者,大家都知道,人类只有一个地球,地球上的山山水水、动物.植物是人类的细胞,如果我们把它损坏了,破坏了大自然的组织,等于消灭人类.因此,环境要与社会公德联系起来,与实践行为作为人格教育的一项重要内容来抓.每个人都要履行保护环境的责任和义务.

Pollution is becoming more and more serious all over the world. As is shown in the cartoon, two cars are giving off waste gas and three people are trying to avoid breathing in the poisonous gas by masking their face with their hands. The poisonous gas sent off by factories, domestic appliances and automobiles has made the air unhealthy for people to breathe.

There is no denying that automobiles are indications of civilization, progress and development; nevertheless , automobiles cause the serious problem of air pollution. Scientists have warned that unless effective measures are taken, the problem of pollution will eventually get out of hand. Actually, people are showing a real concern over the problem. For example, there is an increasingly loud voice from the public for firm action against pollution from automobiles.

Indeed, the earth is our home and we have the duty to take care of it for ourselves and for our descendants. In my opinion, we should work out concrete solutions to the problem of pollution from poisonous gas given off by automobiles. For example, the automobiles should be equipped with a device which can dispose of waste gas so as to prevent it from polluting air. Only in this way can we really solve the problem of air pollution caused by automobiles.

污染变得越来越严重的世界各地。这幅漫画所示,两辆车散发废气和三个人正试图避免吸入有毒气体通过屏蔽自己的脸。工厂的有毒气体罚下,家用电器和汽车污染的空气影响了人们的呼吸。

不可否认,汽车文明的迹象,进步和发展;然而,汽车造成空气污染的严重问题。科学家们警告说,除非采取有效措施,污染的问题最终会失控。实际上,人们显示出真正的担忧的问题。例如,有一个公共的越来越大声对汽车污染公司行动。

事实上,地球是我们的家园,我们有责任照顾它为我们自己和我们的后代。在我看来,我们应该制定具体的解决问题的有毒气体污染的汽车。例如,汽车应该配备一个设备可以处理废气,以防止污染空气。只有用这种方法我们才能真正解决由汽车引起的空气污染的问题。

Air pollution is one of the major problems of the modern world.

A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too.

Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.

Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities.

They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material.

Also, engineers try to design and locate new power plants to do minimum damage to the environment.

However, it may be that we still have a long way to go before we have a "clean" world.

Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do.

People will continually find new ways to control pollution.

In my memory, though my hometown is a small village, it is very beautiful. When I was small, I liked to caught fish in the river, the water was so clean that I could see the fish. As I miss my hometown so much, last week, I went back to my hometown, I found the place in my memory was not like what it was. The trees were not that numerous, the roads became bigger, while there was less place for the river, I saw some dead fish in the river, the water was dirty, the river pollution was so serious! I couldn’t believe it, the beautiful hometown was destroyed by the pollution, it is people’s ambition results in it, they chase for the profit at the cost of polluting the environment. I wish people can pay attention to protect the environment, they are saving themselves, too.

在我的记忆中，虽然我的家乡是个小城镇，但是很美丽。当我还小的时候，我喜欢在河里抓鱼，河水是如此的干净以至于我能看到河里的鱼。由于抵挡不住对家乡的思念，上周，我回到了家乡，我发现我记忆中的城市再也不是它原来的样子了。树没以前的多，道路变得宽阔，然而河道却变得窄些了，我看到河中有一些死掉的鱼，河水是如此的脏，河流污染是如此的严重!我无法相信眼前的一切，美丽的家乡被污染给破坏了，人们的贪念导致了这个结果，他们为了追求利益，不惜以牺牲环境为代价。我希望人们能注意保护环境，这也是在保护他们自己。

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.

In recent years, we can clearly feel the environment around us is more and moreobvious pollution, environmental safety problems have been very serious. Because of our previous policy is heavy economic development, light environmental protection,resulting in environmental pollution, ecological damage is very serious, mainly manifested in the following aspects:

近几年来，我们可以明显的感觉到我们身边的环境污染愈显明显，环境安全问题已十分严重。因为我国以往的政策方针是重经济发展，轻环境保护，所以造成环境污染、生态破坏十分严重，主要表现为以下几个方面：

In the atmosphere of security, since the middle of the twentieth Century, industry andthe rapid development of transportation, causing air pollution is increasing. Air pollutionis harmful to human health, but also affect the growth of plants and animals,destruction of building materials, serious when can alter the earths climate. According to the survey, China each year from air pollution and economic losses amounted to about 100000000000 yuan.

在大气安全方面，20世纪中叶以来，工业和交通运输迅速发展，造成了大气污染的日益加重。大气污染既危害人体健康，又影响动植物的生长，破坏建筑材料，严重时会改变地球的气候。据调查显示，我国每年因大气污染造成的经济损失高达1000多亿元。

In the water security, water pollution in China is very serious, widespread around thedrinking water safety problems, a direct threat to human and animal survival. In recent years, although the investment fund management a lot of Huaihe and other waters, but the effect is not obvious, the overall situation is still deteriorating.

在水安全方面，我国水污染问题十分严重，各地普遍存在着饮用水安全问题，直接威胁到人畜生存。近几年虽然投入大量的资金治理淮河等水域，但效果并不明显，整体情况仍在恶化。

In a biological safety, the invasion of alien species mass, a serious threat to thebiological diversity of china. In fact, the blind introduction of foreign species, damage the environment balance, serious and even lead to disastrous consequences. At the same time, because of the destruction of the ecological environment and wildlifehunting, biological extinction rate is rapidly increasing.

在生物安全方面，大规模的外来物种入侵，严重威胁了我国的生物多样性。事实证明，盲目引进外来物种，会破坏环境平衡，严重时甚至带来灾难性的后果。同时，由于生态环境的破坏和对野生动植物的滥捕滥猎，生物消亡的速度正在迅速增加。

In the security of land, the land desertification and soil erosion is very serious. In addition, the cultivated land quality in China decreased very rapidly, at the same time,because of the serious land pollution phenomenon caused by excessive use ofpesticides, is directly related to food safety problem of residents in our country. China is a developing country, in the face of environmental pollution pressure not only fromChina itself, and applied pressure from some developed countries abroad. Therefore the development of economy and environment is a need for us to issue long face, and it also need to rely on the participation of each and every one of us.

在土地安全方面，我国土地荒漠化和水土流失的情况已十分严重。另外，我国耕地质量下降非常迅速，同时由于过度使用农药等造成的严重的耕地污染现象，直接关系到我国居民的食品安全问题。 我国是一个发展中大国，面对环境污染方面的压力不仅来自国内本身，还有来自国外一些发达国家施加的压力。因此发展经济和治理环境是一个需要我们长久面对的问题，而这也需要靠我们每个人的共同参与。

Dear Mike，

Thank you very much for your concern. Last months several places in Beijing were blanketed with thick yellow fog. Everything around disappeared from oursight. Some highways were closed. Traffic jams were commonly seen in the streets. Many people, especially children and seniors, even found it difficult to breathe. As a result, local hospitals were crowded with people who had problems with their noses and lungs. Part of the cause was the dry weather, but the severely damaged environment contributed a lot to this nightmare. Personally I didn’t get any health problems in the haze because I stayed mostly indoors.But to make a significant change we really have to do more to protect our environment. To live a better life we have to push on with the economy, but it wound be meaningless if we have to achieve it at the cost of our breathing air.

Regards!

Yours，Li Hua

导语：随着人们生活水平的提高，私家车数量不断增加。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!

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, which greatly improves our living standard. We can easily drive cars for sightseeing on weekends. In the second place, cars are a comfortable way to travel, especially in bad weather. Last but not least, the car industry can boost economy by creating many job opportunities in production of steel, rubber, glass and so on. However, there are also many good arguments against cars. First of all, they pollute the environment by emitting harmful gases and giving out loud noises. In addition, cars cause a large number of traffic accidents, which bring great misery to the victims‘ families. 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 common good of the society.

【参考译文】

私家车已成为我国许多地区人民生活的一个重要方面，特别是在北京、上海和中国等大城市。虽然他们给人们带来很多方便，但他们也被广泛批评。有一些理由拥有私家车。首先，汽车可以让人们自由走动，这大大提高了我们的生活水平。周末我们可以很容易地开车观光。其次，汽车是一种舒适的旅行方式，尤其是在恶劣的天气里。最后但并非最不重要的是，汽车工业可以通过创造钢铁、橡胶、玻璃等的就业机会来提振经济。然而，也有许多好论据反对汽车。首先，他们通过排放有害气体和发出大声的噪音来污染环境。此外，汽车造成了大量的交通事故，给遇难者家属带来了极大的痛苦。就我而言，我们应该通过提供更好的大众运输和更好的服务来限制私家车的数量。为了社会的共同利益，每个人都应该牺牲自己的利益。

一篇《天然气锅炉排烟是加剧京城灰霾天气的重要原因》的文章表示，天然气锅炉排烟是造成北京地区“丰富水汽”的主要来源，是加剧灰霾空气的“帮凶”，称北京发展天然气是双刃剑，既有清洁能源的一面，又有排放水汽的负面影响和氮氧化物的污染。

真相：中科院大气物理所研究员王自发表示，按照我国当前的天然气消耗量计算，每年燃烧天然气产生的气态水在3亿吨左右，假如全部转化成液态水(但实际上不可能全部转化为液态水)，平摊在全国人口集中的东部地区(估算面积约360万平方公里)，液态水的厚度连0.1毫米/年都不到，仅占大气中可降水量的几十万分之一，影响微乎其微。所以说，“煤改气”不会显著增加北京市大气中的湿度，不是北京地区“丰富水汽”主要来源。

南开大学冯银厂教授表示，无论是燃煤、燃气还是燃油，都会排放氮氧化物。“煤改气”是否会导致氮氧化物的升高，主要取决于改气之前煤炭的燃烧方式和煤炭品质、改气之后采取的燃烧技术等因素。如果采用了低氮燃烧技术，氮氧化物的排放量就会降低。我国脱硝比脱硫起步晚，近年来大气环境中的氮氧化物浓度下降并不像二氧化硫那么显著。氮氧化物浓度的增加可能会造成二次污染，但这是可控的。而且污染成因和机理非常复杂，不能因为氮氧化物浓度没有明显下降，颗粒物污染依然严重，就说是“煤改气”造成的，这是不科学的。

Cars have created a lot of serious problems in our world.

All the time, they are pumping huge amounts of waste gases into the atmosphere, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels.

But it may take decades for the new models to completely replace the traditional ones.

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 drive private cars.

On the whole, the elimination of air pollution needs the co-efforts from the government and the public.

This problem will be solved only with the help of science and technology.

White pollution persists

WEVE been hearing and talking about it for a fairly long time： curbing what has become known as “white" pollution. But still we are using the white polystyrene （PS） foam food containers and other disposable plastic products， which largely make up this form of littering.

Miandianwang， a well-known local fast-food chain， is still handing out takeout food in these PS foam containers， even though they should been phased out before December 31， 2000， under a Central Government decree. One of the waiters said in its outlet on Hongli Road on Monday that they are going to switch to environmentally friendly containers “some time in the future".

However， the Miandianwang outlet in Sams Club， which is affiliated with Wal-Mart， is offering take-out food in light brown containers which are biodegradable. Liang， a clerk with Sams Club， told Shenzhen Daily yesterday that the club required the Miandianwang outlet to do so in its contract.

According to Liang， all the departments in the club switched to biodegradable containers during the Spring Festival holiday.

Zhao Hua， with the energy division of the Shenzhen Municipal Economic Development Bureau， one of the five municipal government departments involved in the curbing of white pollution in the city， said on Monday that large companies and retailers like Wal-Mart and Vanguard have responded to the decree by switching to biodegradable containers. But she admitted that is just the tip of the iceberg in the seemingly endless war on white pollution in the city.

Zhaos bureau has met with four other relevant departments on several occasions. What they produced is not a feasible solution but an echo or rewording of the Central Government decree， according to Luo Wei from Shenzhen Municipal Legal Affairs Bureau， who is responsible for reviewing this “echo". The ”echo" has now been passed on to the municipal government which is expected to announce it formally in the near future. But Luo said shes not sure if this rewording can play a significant role in eliminating white pollution in the city. “We dont lack laws， regulations or decrees. The real concern is the effective enforcement of these laws or regulations，" said Luo.

Zhao Hua admitted that cities like Shanghai and other coastal cities which are sensitive about their image as tourist destinations are doing a better job in this regard. “Shanghai is said to have produced a very detailed handbook on how to carry out the curbing work and Hainan has even banned disposable foam slippers in hotels，" Zhao said.

Liu Guanqing， president of Shenzhen Xunbao Investment Development Co Ltd， a local manufacturer of biodegradable food containers was very eager to hear the municipal governments decision on the matter. “Since early this year， Ive seen orders fly in. Ill expand production once the government announces its stance on the issue."
