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
谁能给我找一个关于大气污染的英语演讲稿》
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。

让我们使我们的未来光明的。
让我们先清理现在。
有关于环境保护的英语演讲稿
目前，全球荒漠化土地面积已经达到3600万平方公里，占陆地总面积的1／4，成为全球生态的“头号杀手”，而且每年仍以5万至7万平方公里的速度在扩展；全世界受荒漠化危害的国家达110多个，10亿人口受到直接威胁这意味着，地球上已有1／4的土地基本失去了人类生存的条件 森林锐减直接导致了全球六大生态危机。
一、绿洲沦为荒漠 目前，全球荒漠化土地面积已经达到3600万平方公里，占陆地总面积的1／4，成为全球生态的“头号杀手”，而且每年仍以5万至7万平方公里的速度在扩展；全世界受荒漠化危害的国家达110多个，10亿人口受到直接威胁。
这意味着，地球上已有1／4的土地基本失去了人类生存的条件。
二、水土大量流失 水土流失是森林破坏导致的最直接最严重的后果之一。
只要地表有1厘米厚的枯枝落叶层，就可以把地表径流减少到裸地的1／4以下，泥沙量减少到裸地的7％以下；林地土壤的渗透力更强，一般为每小时250毫米，超过了一般降水的强度。
一场暴雨，一般可被森林完全吸收。
由于森林的严重破坏，全球水土流失日益加剧。
目前，全世界有l／3的土地受到严重侵蚀，每年约有600多亿吨肥沃的表土流失，其中耕地土壤流失250多亿吨。
全球地力衰退和养分缺乏的耕地面积已达29．9亿公顷，占陆地总面积的23％。
三、干旱缺水严重 森林被誉为“绿色的海洋”、“看不见的绿色水库”。
据测定，每公顷森林可以涵蓄降水约1000立方米，l万公顷森林的蓄水量即相当于1000万立方米库容的水库。
由于森林锐减及水污染，造成了全球性的严重水荒。
目前，60％的大陆面积淡水资源不足，100多个国家严重缺水，其中缺水十分严重的国家达40多个，20多亿人饮用水紧缺。
预计今后30年内，全球约有2／3的人口处于缺水状况。
四、洪涝灾害频发 水灾与旱灾是一对“孪生子”。
破坏森林，必然导致无雨则旱，有雨则涝。
大量事实说明，森林有很强的截留降水、调节径流和减轻涝灾的功能。
森林凭借它庞大的林冠、深厚的枯枝落叶层和发达的根系，能够起到良好的调节降水的作用。
森林的防洪作用主要表现在两个方面：一是截留和蓄存雨水；二是防止江、河、湖、库淤积。
这两个作用削弱后，一遇暴雨必然洪水泛滥。
五、物种纷纷灭绝 科学家分析，一片森林面积减少10％，能继续在森林中生存的物种就将减少一半。
地球上有500万至5000万种生物，其中一半以上在森林中栖息繁衍。
由于全球森林的大量破坏，现有物种的灭绝速度是自然灭绝速度的1000倍。
联合国预测，1990—2000年每年可能失去了1．5万至5万个物种。
目前，地球上的物种已消失了25％，还有20％—30％存在灭绝的危险。
六、温室效应加剧 近代人类大量使用化石燃料，如石油、煤炭、天然气等，使得大气中二氧化碳的浓度在过去110多年里由270毫升／立方米上升到350毫升／立方米，到21世纪中期将达到600毫升／立方米。
而森林吸收二氧化碳并放出氧气，每公顷森林平均每生产10吨干物质，吸收16吨二氧化碳，释放12吨氧气。
从这六大生态危机可以看出，破坏森林的后果是极其严重的。
科学家们断言，假如森林从地球上消失，陆地90％的生物将灭绝；全球90％的淡水将白白流入大海；生物固氮将减少90％；生物放氧将减少60％；许多地区的风速将增加60％至80％；同时将伴生许多生态问题和生产问题，人类将无法生存。
目前，森林锐减导致的一系列生态危机，已经构成了对人类的严重威胁。
土地资源是三大地质资源（矿产资源、水资源、土地资源）之一，是人类生产活动最基本的资源和劳动对象。
人类对土地的利用程度反映了人类文明的发展，但同时也造成对土地资源的直接破坏，这主要表现为不合理垦植引起的水土流失、土地沙漠化、土地次生盐碱化及土壤污染等，而其中水 土流失尤为严重，乃当今世界面临的又一个严重危机。
据估计，世界耕地的表土流失量约为230亿水土流失是指在水流作用下，土壤被侵蚀、搬运和沉淀的整个过程。
在自然状态下，纯粹由自然因素引起的地表侵蚀过程非常缓慢，常与土壤形成过程处于相对平衡状态。
因此坡地还能保持完整。
这种侵蚀称为自然侵蚀，也称为地质侵蚀。
在人类活动影响下，特别是人类严重地破坏了坡地植被后，由自然因素引起的地表土壤破坏和土地物质的移动，流失过程加速，即发生水土流失。
水土流失是我国土地资源遭到破坏的最常见的地质灾害，其中以黄土高原地区最为严重。
我国目前水土流失总的情况是：点上有治理，面上有扩大，治理赶不上破坏。
全国水土流失面积解放初期为17.4亿亩,到1980年约治理6亿亩。
由于治理赶不上破坏，水土流失面积却扩大到22.5亿亩，约占国土总面积的1\\\/6，涉及近千个县。
全国山地丘陵区有坡耕地约4亿亩，其中修梯田约1亿亩，而另外3亿亩坡地正遭受水土流失的危害。
吨\\\/年。
土壤肥力下降，水土流失可使大量肥沃的表层土壤丧失。
据统计，我国每年流失土壤约50亿吨，损失N、P、K元素约4000多万吨。
水库淤积，河床抬高，通航能力降低，洪水泛滥成灾。
威胁工矿交通设施安全。
在高山深谷，水土流失常引起泥石流灾害，危及工矿交通设施安全。
恶化生态环境。
20世纪30～60年代，人们对于水土流失灾害的认识还停留在对土地造成直接经济损失方面，但在60年代以后，开始联系到人类整个环境所受的影响，包括沉淀物的污染，生态环境的恶化等。
水土流失是地表径流在坡地上运动造成的。
各项防治措施的基本原理是：减少坡面径流量，减缓径流速度，提高土壤吸水能力和坡面抗冲能力，并尽可能抬高侵蚀基准面。
在采取防治措施时，应从地表径流形成地段开始，沿径流运动路线，因地制宜，步步设防治理，实行预防和治理相结合，以预防为主；治坡与治沟相结合，以治坡为主；工程措施与生物措施相结合，以生物措施为主。
只有采取各种措施综合治理和集中治理， 持续治理，才能奏效。
写一篇主题为（let's Ride Bicycle's）的英语演讲稿。
内容包括1目前汽车带来的空气
Nowadays we can see thousand and thousand cars passingthough every rode every city every country. But even though cars bring us convenience,there are still a lot of horrible effects that costing the earth. Cars producegreenhouse gases increases the rate of global warming and damaged the environment.That is why now I strongly suggest we have to start ride a bicycle, i thinkbike is the greatest things that ever invented. First things first, it iseco-friendly which means not like cars it will not produce greenhouse gases canpolluting the air. The cars need fossil fuels to start the engine. Fossil fuelsare not renewable resource; therefore it is scarcity natural resources. Thereforeriding bike is saving the earth. Secondly riding bike is the second chancethat people get fit, many people work in the city do not have the leisure timeto go to the gym even if they want to. Therefore riding bike to work is a wayto exercise and get healthy.
