关于环保的演讲稿（3~5分钟）
五分钟的演讲稿,至少得一千字的,下面推荐一篇,自己修改完善一下! 承诺自然——演讲稿 承诺自然 200万年前，地球在历史的长河中缓缓航行了46亿年后，人——这种不平凡的生命终于诞生了。
地球母亲也许永远也没想到这是她辉煌的开始，却也是噩梦的开始。
200万年对于地球漫长的生命历程来说，只不过是沧海一粟，只不过是微不足道的一瞬，但自从人类的足迹印上这可蓝色星球，地球的命运从此多舛，因为人类对自然的无止境的索取，我们曾经温柔、慈祥的地球母亲变得暴虐无常。
历经无数次沧海桑田，斗转星移，地球母亲的美丽变成了曾经，取而代之的是苍老肮脏和面目全非。
无法想象，如果有一天地球上没有了绿色，那人类的文明将会如何，到那时，也许只是灰飞烟灭，一切的一切都只会淹没在漫天飞沙之中。
当一片片绿波汹涌的森林被无垠的荒漠黄尘所取代，当无忧地在蔚蓝的天空飘荡的白云被漫天滚滚黑烟所替代，当为地球遮风挡雨的臭氧层被无情的氟里昂所破坏，我分明听见了森林的哭泣，白云的叹息，臭氧层的悲伤。
是的，不知从何时起，人类丧失了纯白的灵魂，永恒只对贪婪忠诚。
在周杰伦的歌中，半兽人可以等灵魂序曲的完成，可以维持纯白的象征，可以还原为人，可以等觉悟后前往南方大地重新开垦。
但现实中人类已不能等下去，在等下去只能等来更为残酷的惩罚，甚至毁灭。
包容，是大自然教给我们的，为什么我们不去接受呢
感动，是我们在大自然那里学会了最感动的感动，为什么我们不去感动自然呢
想为了家园长久的美好未来，让我们从现在开始承诺自然，用心呵护每一片绿。
下面请允许我用一首歌来结束我的演讲： 我们企图改变世界的容颜 让我们的生存随着我们的意愿 眼看着世界一天天改变 我们也在一天天的发现 如果我们没有当初的狂野 现在也不会让他们留着泪 就算是你看见沧海便桑田 时间倒退了无数遍 它们的哭泣不会停歇 就算是你看见我们也在变 迫不及待的去冒险 我们的世界不会像重前和你我连成一片
环境污染的演讲稿
近年来，随着地区经济的迅猛发展，环境污染问题也越来越严重，防止环境污染，保护环境，维持生态平衡，已成为社会发展的一项重要举措，也是每个公民应尽的义务。
\ 以下是实地调查出来的报告：\ 造成环境污染的污染源是：1、公共厕所排出的粪便散发出难闻的气味，让人恶心。
2、工厂排出的废水又黑又臭，还浮着一些秽物。
3、工厂排出的废气很刺鼻，会散发到小镇的各个角落。
4、化肥厂排出的气体中含有粉尘、铅、煤灰等对人体有害的物质。
5、公园的草坪上常有游人丢弃的垃圾，既不卫生，又影响市容。
\ 造成环境污染的污染物是：废水、废气、粪便、腐肉、塑料袋、木筷，垃圾等。
\ 污染物对环境和生物有很大的危害：使空气变得浑浊，对人的肺部有很大危害；生活垃圾处理不好会滋生细菌，严重影响人的健康；污水会影响生活水，直接侵害人体。
\ 看了这么多，你是不是对目前的环境有些忧虑呢
对，环境与我们的生活密切相关，保护环境卫生从我做起，从现在做起：不随地吐痰；不乱扔垃圾；拒绝使用一次性木筷；废弃电池和塑料袋要处理好；多植树造林，不践踏草坪；不污染水源。
保护环境，我们责无旁贷
关于保护环境的演讲稿怎么写
初三演讲，演讲时间三分钟 急用
我这里有个竞选干部的演讲稿例子 你参考下各位老师、学长、学弟、学妹们： 大家晚上好。
今天，我在这里，面对这么多注视的目光发表演讲，展示自己。
对我来说，既是一个考验，又是一次难得的机会。
“青春无几，时不我待”，我要抓住这次机会，通过竞选，争取成为汽车系第十五届学生会主席团中的一员。
我先作一下自我介绍，我叫XXX，T343-1班学习委员。
我来竞选，是因为我有以下几方面的优势： 1） 我热心为大家服务。
进入大学以学生会后，我一直我是班委成员之一，热心为同学们服务，认真做班级工作，得到同学们的认可。
马上就要进入大三了，我已不满足于只为一个班集体工作，我要着眼于全系，为给多的同学服务。
2） 勤恳。
我不怕工作忙，就怕没事做。
熟悉我的同学都知道，我是个闲不下来的人，总希望有点事来做。
我一闲下来，就感到空虚。
所以，如果能当选，我会勤勤恳恳的工作。
3） 办事有计划、效率高。
我的学习、生活、工作都按计划进行。
每天早上，我都会花一点时间安排当天要做的事。
我做事不喜欢拖拖拉拉，总是在得到任务后，只要有时间，就立即处理。
以上是我的做事风格：热心、勤恳、高效、有计划。
如果我能当选，在以后的工作中，我将以我的处事风格做好以下几方面的工作： 1） 协助老师，当好助手。
老师是做学生工作的主体，学生干部是辅助者。
我们要利用身处学生群体之中，更了解同龄人的优势，协助老师做好学生工作。
2） 抓好团结互助，营造一种协调的氛围。
学生会是一个大团体，只有搞好团结，才能做好各项工作。
在团结的基础上，充分发挥每个学生干部的工作积极性和创造性，为我系的学生工作贡献自己的一分力量。
3） 重点抓T4和T5级的学风建设，树立良好的学习风气。
另外，还要把T5级新生角色转变作为一个工作重点，让他们尽快适应新的生活和学习环境。
4） 多开展一些活动，丰富同学们的课余文化生活。
以上是我暂时的工作构想，在以后的实际工作中，遇到新的问题，随机应变，以切实可行的方法解决。
总之，目标只有一个：做好本职工作。
“金无足赤，人无完人“，我也有一些缺点和不足。
在以后的工作中，欢迎老师和同学们帮我指出。
我会虚心接受，努力改正。
进入大学以后，我为自己制定了一些目标。

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
课前3分钟演讲稿（环保）
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。
