3分钟英语演讲，关于环境污染的,求助高手
环境（Environment）Like all other living beings, humans have clearly changed their environment, but they have done so generally on a grander scale than have other species. Some of these changes-such as the destruction of the world's tropical rain forests to create grazing land for cattle or the drying up of almost three-quarters of the Aral Sea, once the world's fourth-largest freshwater lake, for irrigation purposes-have led to altered climate patterns, which in turn have changed the distribution of species of animals and plants.Scientists are working to understand the long-term consequences that human actions have on ecosystems, while environmentalists-professionals in various fields, as well as concerned citizens in the United States and other countries-are struggling to lessen the impact of human activity on the natural world.Population Growth（人口增长）Human population growth may be seen to be at the root of virtually all of the world's environmental problems. Increasingly large numbers of people are being added to the world every year. As the number of people increases, more pollution is generated, more habitats are destroyed, and more natural resources are used up. Even if new technological advances were able to cut in half the environmental impact that each person had, as soon as the world's population size doubled, the earth would be no better off than before.The Population Division of the United Nations predicts that the 5.63 billion humans alive in 1994 will increase to 6.23 billion in the year 2000, 8.47 billion in 2025, and 10.02 billion in 2050. The UN's estimate assumes that population will peak and stabilize at 11.6 billion in 2200.Although it is true that rates of population increase are now much slower in the developed world than in the developing world, it would be a mistake to assume that the population growth problem is primarily a problem of developing countries. In fact, because larger amounts of resources per person are used in the developed nations, each citizen from the developed world has a much greater environmental impact than does a citizen from a developing country.Evidence now exists suggesting that the most important factors necessary to lower population growth rates in the developing world are democracy and social justice. Studies show that population growth rates have fallen in areas where several social conditions have been met. In these areas, literacy rates have increased, and women are given economic status equal to that of men and thus are able to hold jobs and own property; also, birth control information is more widely available, and women are free to make their own reproductive decisions.Global Warming（全球变暖）Like the glass panes in a greenhouse, certain gases in the earth's atmosphere permit the sun's radiation to heat the earth but retard the escape into space of the infrared energy radiated back out by the earth. This process is referred to as the greenhouse effect. These gases, primarily carbon dioxide, methane, nitrous oxide, and water vapor, insulate the earth's surface, helping to maintain warm temperatures. If the concentration of these gases were higher, more heat would be trapped within the atmosphere, and worldwide temperatures would rise.Within the last century, the amount of carbon dioxide in the atmosphere has increased dramatically, largely because of the practice of burning fossil fuels-coal and petroleum and its derivatives. Atmospheric scientists have now concluded that at least half of that increase can be attributed to human activity, and they have predicted that unless dramatic action is taken, temperature will continue to rise by between 1° and 3.5° C over the next century. The consequences of such a modest increase in temperature may well be devastating. Sea levels will rise, completely inundating a number of low-lying island nations and flooding many coastal cities such as New York and Miami. Many plant and animal species will probably be driven into extinction, agricultural regions will be disrupted, and the frequency of severe hurricanes and droughts is likely to increase.Depletion of the ozone layer（臭氧层变薄）The ozone layer, a thin band in the stratosphere （a layer in the upper atmosphere）, serves to shield the earth from the sun's harmful ultraviolet rays. In the 1970s, scientists discovered that the layer was being attacked by chlorofluorocarbons （CFCs）, chemicals used in refrigeration, air-conditioning systems, cleaning solvents, and aerosol sprays.The consequences of the depletion of the ozone layer are dramatic. Increased ultraviolet radiation will lead to a growing number of skin cancers and cataracts and also reduce the ability of people's immune systems to respond to infection. Additionally, the growth rates of the world's oceanic plankton, the base of most marine food chains, will be negatively affected, perhaps leading to increased atmospheric carbon dioxide and thus to global warming.Predicting the rate of ozone depletion is difficult. Optimists claim that if international agreements for the phasing out of ozone-depleting chemicals agreed to in Montréal in 1987 are followed, ozone loss will peak in the year 2000. With many of the world's fastest growing countries in the process of industrializing and modernizing, there is reason to believe that destruction will continue to increase well beyond that year.Air pollution（空气污染）A significant portion of industry and transportation is based on the burning of fossil fuels, such as gasoline. As these fuels are burned, chemicals and particulate matter are released into the atmosphere. These chemicals interact with one another and with ultraviolet radiation in sunlight in various dangerous ways. Smog, usually found in urban areas with large numbers of automobiles, can cause serious health problems. Acid rain is a serious global problem because few species are capable of surviving in the face of such acidic conditions. Acid rain has made numerous lakes so acidic that they no longer support fish populations. Acid rain is also thought to be responsible for the decline of many forest ecosystems worldwide.Water pollution（水污染）Estimates suggest that nearly 1.5 billion people lack safe drinking water and that at least 5 million deaths per year can be attributed to waterborne diseases. Water pollution may come from point or nonpoint sources. Point sources discharge pollutants at specific locations-from, for example, factories, sewage treatment plants, or oil tankers. The technology exists for point sources of pollution to be monitored and regulated, although political factors may complicate matters. Nonpoint sources-runoff water containing pesticides and fertilizers from acres of agricultural land, for example-are much more difficult to control. Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes.With almost 80 percent of the planet covered by oceans, people have long acted as if those bodies of water could serve as a limitless dumping ground for wastes. Raw sewage, garbage, and oil spills have begun to overwhelm the diluting capabilities of the oceans, and most coastal waters are now polluted. Beaches around the world are closed regularly, often because of high amounts of bacteria from sewage disposal, and marine wildlife is beginning to suffer.Groundwater pollution（地下水污染）Water that seeps through porous rocks and is stored beneath the ground is called groundwater. Although groundwater is a renewable resource, reserves are replenished relatively slowly. When groundwater is depleted in coastal regions, oceanic salt water commonly intrudes into freshwater supplies. Saltwater intrusion is threatening the drinking water of many areas along the Gulf and Atlantic coasts.The EPA has estimated that, on average, 25 percent of usable groundwater is contaminated, although in some areas as much as 75 percent is contaminated. Contamination arises from leaking underground storage tanks, poorly designed industrial waste ponds, and seepage from the deep-well injection of hazardous wastes into underground geologic formations. Because groundwater is recharged and flows so slowly, once polluted it will remain contaminated for extended periods.Habitat Destruction and Species Extinction（居住环境破坏与物种灭绝）It is difficult to estimate the rate at which humans are driving species extinct because scientists believe that only a small percentage of the earth's species have been described. What is clear is that species are dying out at an unprecedented rate; minimum estimates are at least 4000 species per year, although some scientists believe the number may be as high as 50,000 per year. The leading cause of extinction is habitat destruction, particularly of the world's richest ecosystems-tropical rain forests and coral reefs. At the current rate at which the world's rain forests are being cut down, they may completely disappear by the year 2030. If growing population size puts even more pressure on these habitats, they might well be destroyed sooner.This loss is critical from several perspectives. The economic value of species lost and of natural products and drugs that never will be discovered or produced is incalculable. Similarly, it is impossible to place either a moral or an aesthetic value on our growing list of extinct species. As habitats are destroyed and species lost, the world is increasingly losing threads from the interconnected fabric of life.Chemical Risks（化学成分污染）Pesticide residues on crops and mercury in fish are examples of toxic substances that may be encountered in daily life. Many industrially produced chemicals may cause cancer, birth defects, genetic mutations, or death. Although a growing list of chemicals has been found to pose serious health risks to humans, the vast majority of substances have never been fully tested.Environmental Racism（环境歧视）Studies have shown that not all individuals are equally exposed to pollution. Three of the five largest commercial hazardous waste landfills in America are in predominantly black or Hispanic neighborhoods, and three out of every five black and Hispanic Americans live in the vicinity of an uncontrolled toxic waste site. The fact that the wealth of a community is not nearly as good a predictor of hazardous-waste locations as is the ethnic background of the residents reinforces the conclusion that racism is involved in the selection of sites for hazardous-waste disposal.Environmental racism takes international forms as well. Dangerous chemicals banned in the United States often continue to be produced and shipped to developing countries. Additionally, the developed world has shipped large amounts of toxic waste to developing countries for less-than-safe disposal.Energy Production（能源问题）The world cannot continue to rely on the burning of fossil fuels for much of its industrial production and transportation. Fossil fuels are in limited supply; in addition, when burned they contribute to global warming, air pollution, and acid rain.Nuclear energy as an alternative is opposed by many because of the massive devastation an accident can cause. The accident at the Chernobyl' nuclear power plant in 1986 scattered radioactive contamination over a large part of Europe. Approximately 135,000 people were evacuated, and human health has been dramatically affected. The World Health Organization released a report in late 1995 attributing the explosive increase in childhood thyroid cancer in Belarus, Ukraine, and Russia directly to the accident.One reasonable solution is to combine conservation strategies with the increased use of solar energy. The price of solar energy relative to traditional fuels has been dropping steadily, and if environmental concerns were factored into the cost, solar power would already be significantly cheaper. Although it is desirable to have a wider range of energy options, other alternative sources of power （such as wind, geothermal, or hydroelectric） are not likely to provide large-scale solutions in the forseeable future.ConclusionGlobal environmental collapse is not inevitable. But the developed world must work with the developing world to ensure that new industrialized economies do not add to the world's environmental problems. Politicians must think of sustainable development rather than economic expansion. 帮你找了一些资料，仅供参考。
有关环保的英语演讲稿，3-5分钟左右
（1） 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?（2） Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do. For example, we can go to school by bike or walk, it can exercise. If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment. 现在，我们身边的汽车不断的多了起来，环境也越来越糟糕
以至于我们周围的空气有很多有害物质。
所以，我们要苏身边的小事做起。
比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。
有时间的话可以少用电梯，多爬楼梯。
我们不仅能锻炼身体,也能保护我们的环境。
（3）文章文体：议论文。
文章要点：1.保护环境的重要性；2.学生在家庭中节约能源的具体做法和感想；3.今后的打算。
文章框架：文章应该是三部分两段式。
第一段（包括要点前两部分）1.环保的重要性；2 接着是站在学生的角度谈谈家庭节约能源的具体方法，第二段写第三要点，即谈谈今后打算。
重要句型短语：It is important to protect our environment, the energy in the world is limited. turn off the light and other appliance when you ,re not using them, we'd better not waste the energy, use public transportation, recycle the waste，I can learn more to develop new and clear energy, like the energy from the wind and solar 等。
参考例文： With the development of our society, energy in the world becomes 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. What's 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.（4）Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful. (最近我们班开了个班会讨论什么是光荣和耻辱。
)It is really a pity to see all this in our school.(很遗憾在学校看到这些现象)Some students don’t respect their teachers or parents. (不尊敬老是和父母)Some don’t take their studies seriously and cheat in exams. (作业不认真，考试作弊)Some throw wastes everywhere and pollute the environment . (到处乱扔垃圾污染环境。
)It is honorable to obey the law and rules , care much about our class and study hard.(关心班级、努力学习、遵纪守法是光荣)It is shameful to break school rules, to be selfish or to make little effort to achieve success.(违反学校纪律、自私 骄傲是可耻的)We should respect others and think more of them than of ourselves.(我们应该尊敬别人经常关心别人)We should work hard and make much more progress to repay the society.(我们应该努力学习取得更大进步从而回报社会。
)We should try our best to keep the environment clean。
(我们应该想方设法保持干净的环境。
) （5） 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.保护环境目前环保还存在着许多问题。
最严重的问题就是空气、水和土壤的严重污染。
污染的空气对人类的健康十分有害。
污染的水引起疼病，造成死亡。
更有甚者，随着现代社会的迅速扩建，植被大大的减少。
为了保护环境，各国政府做了大量的工作。
采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。
因此，在当今的环保中政府起着最重要的作用。
我的看法是，为了保护环境，政府应当采取更具体的措施。
首先，应当通过教育的方法使人们充分謒到环境保护的重要性。
第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。
最后，要严惩那些故意破坏环境者。
使他们破坏环境就是毁灭人类自己。
Hello: everyone!Now I want to talk about a beatiful world! When I was young,I always dreamed that I lived in a beautiful country. There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing. The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment. Everyone should make a contribution to protect the environment. Taking care of our environment is very important.Where ever you live,you can do something around your neighbourhood. Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls? Have you ever cut down trees?If your answers are No,it means that you have already helped protect our environment. It is our duty to keep our envionment clean and tidy. You might ask yourself,Have I ever picked up some rubbish and thrown it into a box?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?If your answers areYes,it means that you have already done something useful to improve the environment. Now I want to say :Let`s do our best to make our world more beautiful!望采纳

The ideals are very important to all of us. But what are ideals? Now let’s look at the following famous sayings. The famous Russian litterateur Lev Tolstoy said, “Ideal is the beacon. Without ideal, there is no secure direction; without a direction, there is no life.” The famous American statesman Carl Schurz said, “Ideals are like the stars---we never reach them, but like mariners, we chart our course by them. ” The famous American scientist Albert Einstein said, “The ideals which have lighted my way, and time after time have given me new courage to face life cheerfully have been kindness, beauty and truth.” 译： 理 想 是 什 么
理想对于我们所有的人来说都是很重要的。
但是什么是理想呢
现在让我们看看下面的一些名言。
俄罗斯著名文学家列夫. 托尔斯泰说：“理想是灯塔。
没有理想，就没有坚定的方向；没有方向，就没有生活。
” 美国著名政治家卡尔.舒尔茨说：“理想犹如天上的星星，我们犹如水手，虽然我们永远够不着它们，但它们可以指引我们的航程。
” 美国著名科学家阿尔伯特. 爱因斯坦说：“曾经为我指路、并不断给我新的勇气，使我欣然面对人生的理想是真、善、美。

跪求：三分钟英语演讲稿
环保问题: (1) As is apparently revealed in the pie charts above, forty-eight percent of people surveyed have never heard of the International No Motor Vehicle Day while fifty-seven percent are willing to give up driving on such a day. What is betrayed in the pie charts is most thought-provoking. The implied meaning of the pie charts is both disappointing and exciting. On the one hand, much necessary work still needs to be done with respect to environmental protection. The public ignorance of relevant environmental protection results from inadequate and limited popularity of environmental protection knowledge by relevant government departments at different levels. Since environmental protection is an international issue, we must constantly introduce the advanced and practical practice in other countries to our general public. Only in this way can we promote environmental protection in China. On the other hand, the enhancement of the public awareness of environmental protection is a welcome development. Over the past years, as people’s living standard improves, people attach more importance to the quality of their life. They have a better understanding of the relationship between environment and their daily life. As a result, they are more interested in following positive international models. In sum, we have got a mixed feeling toward the very fact revealed in the pie charts. In my view, necessary measures should be immediately taken to ensure a nice environment. First of all, government departments at all levels must play a more active role in popularizing international experience and practice of environmental protection. What’s more, the general public should be encouraged to participate more actively in environmental protection. Only in this way can we live in a healthy and harmonious environment.

(3)打好环保比赛、创建绿色北京 尽管2008北京奥运会离我们还有3年之遥，但有一项规模宏大的特殊比赛已经拉开了序幕。
这场比赛的参加者并非来自世界各国的体育选手，而是身处北京的每一位公民，比赛的场所就是我们身边的街区小巷。
我想大家已经想到了我所说的这项特殊比赛，这就是创建绿色北京、保护美好环境。
那么在这场环保大赛中，我们究竟要与谁一比高低
是繁华现代的洛杉矶、风光迷人的悉尼、还是古老神奇的雅典
都不是
比赛的对手就是我们自己，就是我们自身淡漠的环保意识。
几年前有幸在美国加州度过的一段时光，既让我享受了那里宜人的环境，更让我领略了当地人民高度的环保意识。
每当说到城市环保，我的眼前总会浮现出加州那蔚蓝的天空、明媚的阳光、碧绿的草地以及嬉戏在树枝间的松鼠、彩蝶和百灵鸟。
记得刚到美国时，常去爸爸工作的美国地质调查局玩耍，每次均能看到许多人骑自行车上下班，而其中一位满头白发的骑车老人，引起了我的好奇。
我问爸爸，那个爷爷为什么总骑车上班，是不是没钱买车
爸爸笑道：没钱买车
嘿，说出来吓死你，他可是世界上顶级的大科学家。
要论钱，他可以买一个车队呢。
那他咋不买车呢
骑车多累呀
他有车，但平时除非下雨或购物，一般不去开。
在美国有许多人都是环保主义者，为了节约能源和减少汽车尾气对大气的污染，他们用实际行动倡导人们尽量少开车。
而我们所居住的这座美国城市，还特别将每年的5月19日定成了'骑车上班日'，以支持和宣传这种有效的环保行为。
后来，我还在经常的搭车出行中获知了他们的另一件环保趣事：在美国的许多州，政府为了鼓励大家多坐公交车或几人合用一辆车，以节省能源和缓解交通压力，在城市内一些主干道路上开辟有专门的'钻石车道'，只有乘坐了二人或二人以上的车辆才从此通过。
美国人民这种自觉的环保意识和政府有效的环保措施使我从内心对他们充满了敬佩。
并深刻地影响了我的环保理念。
回国后，常常有人问我：美国好吗
我总会脱口而出：确实好
最好的是环境。
说句真心话，回国三、四年，美国那边同学和老师的面孔已经逐渐模糊，但加州那宜人的自然环境，却每每清晰地浮现在我的眼前，成为我最深的记忆和期盼故地重游的缘由，也成了我心目中北京环境的蓝图。
2008奥运会为我们倡导和实施北京的环保提供了契机，北京能否有朝一日也拥有象加州那样美丽的环境
答案是肯定的。
但需要我们以真正的环保之心和切实的环保行动去一步一步地实现。
从现在开始，如果每一位有车的朋友一星期可以少开一、两次车，每个让家长用车接送的同学一周能主动让家长少接送一两趟而改乘公车或骑自行车，我们就会有拥有更多的蓝天……。
只要我们每一位北京市民都能够自觉的从身边的环保小事做起，加州的蓝天、白云和绿草地就会在北京安家，美国的松鼠、彩蝶和百灵鸟就会来北京落户。
涓涓细流可以汇成滔滔江海，片片绿叶能够造就莽莽森林。
只要我们每一位北京市民都拿起手中的环保之笔，在我们所处的街头巷尾，为北京这幅美丽而古老的画卷添上自己的一抹绿色，就能使北京掩映在绿色的海洋中。
让我们一起行动起来，用我们集体的力量来打赢这场环保之赛，向全世界展现一块最大的金牌，这就是绿色北京、精彩奥运。
Win Competition of Environment Protection for Beijing Although the 2008 Olympics are still three years away, another special competition has already started in Beijing. This time, the competitors are not the athletes from all over the world, but the people living in Beijing. The special competition is not held in a stadium, but in every street and every corner of Beijing. I suppose some of you may have already guessed what the special competition is. Yes, it is the competition of protecting our environment and creating a green Beijing for the 2008 Olympic Games. Someone may ask who is our rival in this competition? The modern Los Angeles, the charming Sydney, or the historic Athens? No, none of them. The real rival is ourselves. It is our bad habits of neglecting to protect environment in our daily life. Several years ago, I was very lucky to have an opportunity to live in the United States for about two years. I not only enjoyed the beautiful environment there, but also appreciated the American people's active way of protecting their environment. Now, whenever the environment protection is mentioned, a beautiful view of California will arise in my mind: white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and small animals playing happily among the trees. I remember that at the beginning of my coming to America, I often went to my father's working place, the United States Geological Survey, to have fun. Each time I found a lot of people riding bicycles to their offices. Among the cyclists, an old man with white hair attracted my attention. Curiously, I asked my father, Why does the old man ride his bike to work every day? Doesn't he have enough money to buy a car? Father laughed, No, not because of money. Actually, he is one of the greatest scientists in the world. He can afford to buy a motorcade if he likes. He is just an environmentalist and usually doesn't drive unless going shopping, or in bad weather. In America, there are a lot of environmentalists, who actively protect their environment. For example, in Palo Alto city we are living now, there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars. Later, I also learnt another interesting fact of environment protection there. In some states of America, in order to decrease air pollution, save energy and reduce traffic jams, state governments encourage people to take buses to work or to share a car among several people. They even set special diamond lanes in some main streets, which are only for the vehicles with 2 or more people. The positive actions of American people and the effective measures the American government takes in environment protection fully won my respects and deeply affected my consciousness in environment protection. When I was back in China, people often asked me: What do you think of America? I always bolt out: Wonderful, especially the beautiful environment. Frankly speaking, after several years, the faces of my American teachers and friends have gradually faded away from my mind, but the blue sky, green grass and lovely animals in California often arise in my mind, and became my dream of visiting there again. The 2008 Olympics provide us with the opportunity to publicize and practise environment protection in Beijing. Is it possible for Beijing to Is it possible for Beijing to become as beautiful as California? The answer is yes, but the dream needs every Beijing citizen's full support and active moves to accomplish. From now on, if every student who is driven to school can take bus or ride bicycle to school once a week, if every car owner goes to work in a car pool once a week, we can make a difference. If everyone can actively protect the environment in our daily life, the blue sky, green grass and lovely animals in California will appear in Beijing. Tiny streams can combine into a vast ocean, small trees can together be an immense forest. Beijing is often described as a beautiful and aged picture. If every Beijing citizen adds a trait of green on the picture, the whole Beijing will become an ocean of green. Let us unite together to win the competition of environment protection in Beijing, and present the world a big gold medal. That is Green Beijing, Great Olympics

关于环保的英语演讲稿（带翻译的）
The world we live in is becoming more and more intolerable because of environmental destruction. For example , forest destruction results in decrease of planting land and unpleasant weather. In addition, man is faced with problems of water pollution and air pollution. A lot of measures have been taken. Planting trees helps improve and beautify the environment. Besides, laws concerning environmental protection have been put into effect and achieved good results. However, the problem of environmental protection remains far from being solved. On the one hand, the environment pollution and destruction are getting worse and worse in the modern world. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. In a word, there is a long way to go before we enjoy a clean and comfortable world.我们生活的世界变得越来越难以忍受,因为环境破坏的原因。
例如,森林的破坏导致减少种植的土地和令人不快的天气。
此外,人类正面临的问题和被污染的空气污染的水。
很多已经采取措施。
植树有助于提高和美化环境。
除此以外,环境保护法律已经实施,取得了良好的效果。
然而,问题的环保仍难以解决。
另一方面,污染、破坏环境越来越糟在现代世界中。
另一方面,缺乏知识的环境保护问题求解的制约。
一言以蔽之,还有很长的路要走,我们享受了干净、舒适的世界。

Courage -- John KennedyThe courage of life is a less dramatic spectacle than the courage of a final moment; but it is no less a magnificent mixture of triumph and tragedy. A man does what he must – in spite of personal consequences, in spite of obstacles and dangers and pressures – and that is the basic of all human morality. To be courageous … requires no exceptional qualifications, no magic formula, no special combination of time, place and circumstance. It is an opportunity that sooner or later is presented to us all. Politics merely furnishes one arena which imposes special tests of courage. In whatever arena of life one may meet the challenge of courage, whatever may be the sacrifices he faces if he follows his conscience – the loss of his friends, his fortune, his contentment, even the esteem of his fellow men – each man must decide for himself the course he will follow. The stories of past courage can define that ingredient – they can teach, they can offer hope, they can provide inspiration. But they cannot supply courage itself. For this each man must look into his own soul.勇气——约翰。
肯尼迪人生之中的勇气，常常不像千钧一发时刻的要求那样充满戏剧性；但是它却同样是一个有关胜利与悲剧的壮观结合体。
一个人要去做他必须做的任何事情——将个人得失置之度外，诸多的障碍、危险、和压力抛诸脑后——这便是人类一切道德的基础。
勇敢。

不需要额外的条件，也没有奇妙的规则，同样也不需要时间、地点和情势的特异结合，我们每个人迟早都会遇到这样一个机会。
政治只不过是对勇气进行特别考验的一个场所罢了。
无论在人生的何种场合下遭遇勇气的挑战，也不论是为了遵从自己的良知而将面对的牺牲——朋友、财富和满足的丧失，甚至于其他人对你的尊重——每个人都必须自己决断其所遵行的方针路线。
他人勇敢的故事可以阐述那个因素——能够教导我们，为我们提供希望和灵感，但却不能给予我们勇气。
因此，每个人必须深入到自己的灵魂之中去寻找勇气。
