With the intensification of human activities, the ozone layer of the earth's surface appears serious hole. Maybe ozone layer is abstract to many people. Let me take a metaphor, ozone layer just like the clothes of our human beings. If our clothes are damage, we will get hurt at last. Recently, as the developing of science and technology, there are more and more new products coming into the world. They bring great convenience to human beings, but they also join the group of damaging ozone sphere at the same time. For example, Freon coming from refrigerator does harm to the ozone sphere. If the ozone layer is destroyed, our mankind will have to face great damage. We will have more chance to get skin cancer, cataract and so on. And there are other living things will be affected. The marine ecosystem also couldn't avoid this disaster.
隨著人類(lèi)活動(dòng)的加劇,地球表面的臭氧層出現(xiàn)了嚴(yán)重的空洞。對(duì)于很多人來(lái)說(shuō)臭氧層也許是很抽象的。讓我來(lái)打個(gè)比方吧,臭氧層就像人類(lèi)的衣服。如果我們的衣服壞了,最后我們肯定會(huì)受傷。近年來(lái),隨著科學(xué)技術(shù)的發(fā)展,出現(xiàn)了越來(lái)越多的新產(chǎn)品。它們給人類(lèi)帶來(lái)了極大的便利,但是他們同時(shí)也破壞了臭氧層。例如,來(lái)自冰箱的氟利昂就會(huì)傷害臭氧層。如果臭氧層被破壞,我們?nèi)祟?lèi)將面臨巨大傷害。我們患皮膚癌,白內(nèi)障等疾病的幾率會(huì)上升。還有其他的生物都將受到影響。海洋生態(tài)系統(tǒng)也無(wú)法避免這場(chǎng)災(zāi)難。
Therefore, we need to do something to protect the ozone sphere to protect ourselves. We should not use air conditioning, refrigerator, cars, spray and the product containing CFCs. But I think the first thing we need to do is improving our environmental protecting conscious. How many people know that 16th, September of every year is the International Ozone Layer Protection Day? In order to make a healthy living environment and the future of human being, please try your best to do something.
因此,我們應(yīng)該要做一些事情來(lái)保護(hù)臭氧層,保護(hù)我們?nèi)祟?lèi)自己。我們不應(yīng)該過(guò)多地使用冷氣,冰箱,汽車(chē),噴霧劑以及含氯氟烴碳化物的產(chǎn)品。但我認(rèn)為我們首先需要做的事情是提高我們的環(huán)保意識(shí)。有多少人知道,每年的九月十六日是國(guó)際臭氧層保護(hù)日?為了人類(lèi)的未來(lái)并營(yíng)造一個(gè)健康的生活環(huán)境,請(qǐng)盡量做點(diǎn)事情吧。
給你推薦一篇:人類(lèi)不斷向地球排放二氧化碳等廢氣,把大氣弄臟了,使地球像在大熱天里穿了一件臟棉襖,體溫不斷地升高。過(guò)往我們?cè)诙齑┐竺抟\,戴棉手襪,現(xiàn)在只穿一件毛衣也不覺(jué)得冷,這就是臭氧層被破壞的表現(xiàn)。由于各種廢氣的排放,使臭氧層產(chǎn)生了“空洞。臭氧層的作用很大:臭氧層能夠吸收太陽(yáng)光中的波長(zhǎng)300 μm以 下的紫外線(xiàn),保護(hù)地球上的人類(lèi)和動(dòng)植物免遭短波紫外線(xiàn)的傷害。所以臭氧層猶如一件宇宙服保護(hù)地球上的生物。
臭氧層是地球一道天然屏障,使地球上的生命免遭強(qiáng)烈的紫外線(xiàn)傷害。然而,近10多年來(lái),地球上的臭氧層正在遭到破壞。
臭氧層被破壞以后,有不少的危害:首先,它會(huì)影響人類(lèi)的健康。臭氧層被破壞后,吸收紫外線(xiàn)的能力大大降低,使得人類(lèi)接受過(guò)量紫外線(xiàn)輻射的機(jī)會(huì)大大增加了。一方面,過(guò)量的紫外線(xiàn)輻射會(huì)破壞人的免疫系統(tǒng),使人的自身免疫系統(tǒng)出現(xiàn)障礙,患呼吸道系統(tǒng)傳染性疾病的人數(shù)大量增加;另一方面,過(guò)量的紫外線(xiàn)輻射會(huì)增加皮膚癌的發(fā)病率。另外,過(guò)量紫外線(xiàn)輻射還會(huì)誘發(fā)各種眼科疾病,如白內(nèi)障、角膜腫瘤等。其次,它會(huì)影響農(nóng)作物的生產(chǎn)。再次,它會(huì)影響水生生態(tài)系統(tǒng)。對(duì)于臭氧層所產(chǎn)生的空洞,我們?cè)撛鯓尤ァ靶扪a(bǔ)”它呢?
愛(ài)護(hù)臭氧層,要求我們每個(gè)人都采取實(shí)際行動(dòng)去少用或者不用對(duì)臭氧層有損害的氟氯碳、哈龍、氯氟烴、甲基溴等物質(zhì),因?yàn)槭褂冒@些物質(zhì)的產(chǎn)品會(huì)導(dǎo)致對(duì)臭氧層的消耗。
下面列舉在日常生活中含有消耗臭氧層物質(zhì)或生產(chǎn)中使用這些物質(zhì)的物品,我們應(yīng)盡量少用或不用它,如:冰箱、空調(diào)等制冷設(shè)備(包括家電、運(yùn)輸制冷、工商制冷)、泡沫(大量存在于沙發(fā)、一次性發(fā)泡餐盒、汽車(chē)內(nèi)飾發(fā)泡件、保 溫噴涂)、滅火劑、氣霧劑(摩絲、殺蟲(chóng)劑、外用藥噴霧劑)、清洗劑、膨脹煙絲等。
人類(lèi)共同寄居的地球和共同享有的天空是不可分割的整體。讓我們積極行動(dòng)起來(lái),為了地球上的生命,為了保護(hù)我們賴(lài)以生存的空間,從我做起,從身邊的小事做起。我相信,有了科學(xué)的方法,再加上我們的實(shí)際行動(dòng),在不遠(yuǎn)的將來(lái),我們將擁有一片美麗而完整的藍(lán)天。
您好!一 Ozone depletionOzone depletion describes two distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total amount of ozone in Earth's stratosphere since the late 1970s; and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions during the same period. The latter phenomenon is commonly referred to as the ozone hole. In addition to this well-known stratospheric ozone depletion, there are also tropospheric ozone depletion events, which occur near the surface in polar regions during spring.The detailed mechanism by which the polar ozone holes form is different from that for the mid-latitude thinning, but the most important process in both trends is catalytic destruction of ozone by atomic chlorine and bromine.[1] The main source of these halogen atoms in the stratosphere is photodissociation of chlorofluorocarbon (CFC) compounds, commonly called freons, and of bromofluorocarbon compounds known as halons. These compounds are transported into the stratosphere after being emitted at the surface. Both ozone depletion mechanisms strengthened as emissions of CFCs and halons increased.CFCs and other contributory substances are commonly referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (270–315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern leading to adoption of the Montreal Protocol banning the production of CFCs and halons as well as related ozone depleting chemicals such as carbon tetrachloride and trichloroethane. It is suspected that a variety of biological consequences such as increases in skin cancer, damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.二acid rainAcid rain is rain or any other form of precipitation that is unusually acidic. It has harmful effects on plants, aquatic animals, and infastructure. Acid rain is mostly caused by human emissions of sulfur and nitrogen compounds which react in the atmosphere to produce acids. In recent years, many governments have introduced laws to reduce these emissions.Scientists have suggested direct links to human health. Fine particles, a large fraction of which are formed from the same gases as acid rain (sulfur dioxide and nitrogen dioxide), have been shown to cause illness and premature deaths such as cancer and other diseases For more information on the health effects of aerosols see particulate health effects.In the United States, many coal-burning power plants use Flue gas desulfurization (FGD) to remove sulfur-containing gases from their stack gases. An example of FGD is the wet scrubber which is commonly used in the U.S. and many other countries. A wet scrubber is basically a reaction tower equipped with a fan that extracts hot smoke stack gases from a power plant into the tower. Lime or limestone in slurry form is also injected into the tower to mix with the stack gases and combine with the sulfur dioxide present. The calcium carbonate of the limestone produces pH-neutral calcium sulfate that is physically removed from the scrubber. That is, the scrubber turns sulfur pollution into industrial sulfates.三atmosphere pollutionAtmosphere pollution is the human introduction into the atmosphere of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the environment. atmosphere pollution causes deaths and respiratory disease atmosphere pollution is often identified with major stationary sources, but the greatest source of emissions is mobile sources, mainly automobiles. Gases such as carbon dioxide, which contribute to global warming, have recently gained recognition as pollutants by climate scientists, while they also recognize that carbon dioxide is essential for plant life through photosynthesis.The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.。
第一段There are still many problems of environmental protection in recent years.(環(huán)境污染的現(xiàn)狀)One of the most serious problems is the serious pollution of air, water and soil.
第二段(具體分析)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.
第三段(產(chǎn)生環(huán)境污染的原因)Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc.
第三段(治理這種污染的方法) 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.
第四段(自己的看法)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.

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.
Our surroundings are being polluted fast and man's present efforts can not prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities and the growing use of man-made materials. What can explain and solve this problem? The fact is that Pollutionis caused by man -- by his desire for a modern way of life. We make "increasing industrialization" our chief aim.So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children.There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, Pollutionhas become a serious problem. Isn't it time we stopped to ask ourselves where we are going-- and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker,"I've some good news and some bad news. The good news is that we're making rapid progress at 530 miles per hour. The bad news is that we're lost and don't know where we're going. " The sad fact is that this becomes a true story when speaking of our modern society.

When the enviroment is mentioned,a beautiful view will arise in my mind:white clouds flying across the blue sky,green grassplot sprinkied with colorful flowers and small animals playing happily among the trees。
So amazing,but it is so far from us . Now the world has become crowded ,forests are dispearing,rivers are polluting with dangerous chemical,lovely birds loss their warm houses。 My dear friends ,we must wake up and do something to change it __in better ways ! Saving the recource ,the batteries,the aged newspapers ,the empty glass bottles,we will classify them,then put them in different trash bins ;when we shopping ,we will bring nylon bags instead of plastic bags ;making the best use of nature light and shut off the electrical light conveniently。
All in all,we should start from every little thing around us .Come on ,my dear friends ,with this new start ,I firmly believe ,that we will live in a brand new age of green trees ,clean air ,crystal water ,blue sky and more promising world!Of course ,the fairy of nature--- graceful swans will come back to us and live with us forever ! 一說(shuō)到環(huán)境,我的腦海中就會(huì)浮現(xiàn)一幅美麗的場(chǎng)景:湛藍(lán)的天空中白云朵朵,嫩綠的草地上花兒繽紛,就連小動(dòng)物們都在樹(shù)叢間快樂(lè)的嬉戲玩耍,多么迷人的畫(huà)面啊,而它卻離我們好遠(yuǎn)?,F(xiàn)在的世界變得擁擠不堪,森林不見(jiàn)了,小河被危險(xiǎn)的化學(xué)物質(zhì)污染了,可愛(ài)的小鳥(niǎo)也失去了那溫暖的小窩。
親愛(ài)的朋友們,我們得覺(jué)醒了,讓我們做些事情來(lái)使一切變得更好吧。讓我們珍惜能源,將廢電池,舊報(bào)紙,空的玻璃瓶,都一一歸類(lèi),放到不同的垃圾桶里。
