求关于水污染的英语演讲稿 实在没有英语的汉语的也行啊 谢谢！

话说我也写过o(╯□╰)o

Dear audience,it's my honor to speak here,and I am very glad to share my topic with you. Then today I'd like to state my view on the water pollution problem. It is generally accepted that water pollution is a serious public hazard today. Rivers all over the world are becoming polluted with garbage and dangerous chemicals. Ships contribute to the problem because they rely on rivers for disposing of wastes. Oil and other chemicals can kill fish and make water unsafe for drinking. Because they rely on rivers for disposing of wastes. Oil and other chemicals can kill fish and make water unsafe for drinking. In a word, polluted water is a big problem to everyone.

As is known to all, people depend on water to live on. They should be involved in finding a solution to this problem. I think, certain counter measures need to be taken as soon as possible. To begin with, the governments of all countries are supposed to formulate rules and regulations to deal with the pollution problem. In addition, factories in towns and cities must be prohibited from draining waste liquids into rivers before they are totally treated and purified. I feel if they violate relevant rules or laws, they should be fined heavily. Certainly, there are some other cures which are worth adopting.

As far as future prospect is concerned, I am sure that good results will be achieved in this respect. Rivers which used to be contaminated by industrial wastes will be cleaned and fish which could not live there a few years ago will be again. To conclude, it seems obvious that tomorrow will be better and brighter only if everyone does his part and tries hard to seek solutions for its control.

Thank you for your listening, you are indeed wonderful audiences.

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.

Conclusion

Global 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.

用“留住一桶水”为题，写一篇英文演讲稿

英文版：简要介绍节约用水的原因和具体做法。

WHY CONSERVE?

Water conservation is the most cost-effective and environmentally sound way to reduce our demand for water. This stretches our supplies farther, and protects places like Mono Lake. For example, the city of Los Angeles has grown by 1 million people since the 1970s, but still uses the same amount of water. Using less water also puts less pressure on our sewage treatment facilities, and uses less energy for water heating.

THE WATER AND ENERGY CONNECTION

Saving water also saves energy. 6.5% of the energy used in the state of California is for pumping and treating water--in fact, pumping water south (and uphill) in the State Water Project accounts for 2-3% of all the electricity used in the state. And for your personal energy bill, using less hot water saves on water heating. On the flip side, saving energy and using alternative energy saves water--electricity production from fossil fuels and nuclear energy is responsible for 39% of all freshwater withdrawals in the nation.

WHAT CAN I DO?

There are many effective ways to conserve water in and around your home. Look through this list for ways that will work for you. Many of these tips were gleaned from materials published by the Metropolitan Water District of Southern California (MWD). Indoor savings are based on a family of two adults and one child.

In the Bathroom

1. Put a plastic bottle or a plastic bag weighted with pebbles and filled with water in your toilet tank. Displacing water in this manner allows you to use less water with each flush. Saves 5 to 10 gallons a day. That's up to 300 gallons a month, even more for large families. Better yet, for even greater savings, replace your water-guzzling five to seven gallon a flush toilet with a one and a half gallon, ultra-low flush model.

2. If you're taking a shower, don't waste cold water while waiting for hot water to reach the shower head. Catch that water in a container to use on your outside plants or to flush your toilet. Saves 200 to 300 gallons a month.

In the Kitchen

1. If you wash dishes by hand--and that's the best way--don't leave the water running for rinsing. If you have two sinks, fill one with rinse water. If you only have one sink, use a spray device or short blasts instead of letting the water run. Saves 200 to 500 gallons a month.

2. When washing dishes by hand, use the least amount of detergent possible. This minimizes rinse water needed. Saves 50 to 150 gallons a month.

Outside

1. Put a layer of mulch around trees and plants. Chunks of bark, peat moss or gravel slows down evaporation. Saves 750 to 1,500 gallons a month.

2. If you have a pool, use a pool cover to cut down on evaporation. It will also keep your pool cleaner and reduce the need to add chemicals. Saves 1,000 gallons a month.

3. Water during the cool parts of the day. Early morning is better than dusk since it helps prevent the growth of fungus. Saves 300 gallons.

4. Don't water the lawn on windy days. There's too much evaporation. Can waste up to 300 gallons in one watering.

你们一定都看过这样一则公益广告：电视画面上有一个水龙头，正在艰难的往外滴着水，滴水的速度越来越慢，最后水就枯竭了。然后画面上上出现了一双眼睛，从眼中流出了一滴泪水。随之出现的是这样一句话：“如果人类不珍惜水，那么我们能看到的最后一滴水将是我们自己的眼泪。”水是生命之源，假如地球上没有水，那么地球母亲就不会孕育出我们人类的子孙万代。因为最早的原始生命首先是在海洋中孕育形成，逐渐扩展到陆地上。所以说，水是生命的摇篮。人类的生存和发展也离不开水。因为我们每天要喝水，粮食的生长离不开水，工业生产离不开水。水还是大自然的“空调器”，炎热的夏天，正当人们感到酷暑难耐时，来一场雨该有多痛快呀!走在海边，海风习习，一扫酷热烦躁的情绪；当寒冷的冬季到来时，海水把储存的热量源源不断地送给它周围的陆地……这些都是水的作用。

水，真的不值线吗?节约用水真的不重要吗?全世界的水百分之九十三是咸水，不能喝。淡水只占有百分之七，而能喝的水只有百分之零点八。全世界五十亿人口，就靠饮用这只占百分之零点八的淡水，看，水多可贵呀!我们国家的水资源虽然非常丰富，但可以用的淡水资源却很少，并且随着工业的发展，水污染成了一个严重的问题，很多工业废水污染得臭不可闻，这是多么可怕的一件事啊!即将到来的3月22日是世界水日。每年的这一天，世界各国都会宣传：大家要爱惜水资源，保护生命之水。其实，不光在这一天，在我们生命中的每一天，都应该珍惜每一滴水，用实际行动珍爱生命之水!

你们知道节约用水的意义吗?请看一笔帐：一吨水大约可供炼钢150千克，发电每小时一千度，生产化肥500千克，织布220米，磨面粉34袋。“滴水成河”，如果人人节约用水，积累起来，就可以派上多在的用处啊!

Water Pollution

Water pollution is caused by waste from factories and cities. Oceans are able to clean themselves, but certain seas, once they become dirty, are not able to do so. One example is the Mediterranean which lies between Europe and Africa. It has onlyeone narrow entrance to the ocean in the west. On quarter of the shores of the Mediterranean are polluted and are no longer safe for swimming, as a lot of diseases are present in the water. In most places it is not safe to eat the fish.

Lakes also have the same problems. Lake Baikal in Asia was once the cleanest in the world, with over 700 different kinds of plant and animal life. Now, however, the waters of this great lake, which is also the world’s deepest (over 1,740 metres), have been dirtied by waste from a chemical factory.

In 1989 an oil tanker hit a rock off the northwest coast of Alaska. 35,000 tons of oil poured into the sea. The accident was one of the worst in history. More than 34,000 birds and 10,000 animals were killed. 4,800 square kilometres of ocean were polluted.

意思:

水污染

水的污染是由于工厂和城市的废物引起的。大洋能够自身清除污染，但是某些海域一旦被污染，却没有自身清污的能力。位于欧洲和非洲之间的地中海就是一个例子。它只在西部有一个狭窄的通往大洋的入口。四分之一的地中海海岸被污染了，而且由于水中带有大量病菌，所以在水中游泳就不再安全了。大多数地方，吃鱼也不保险。

湖泊也遇到了同样的问题。亚洲的贝加尔湖曾经是世界上最清洁的湖，湖里有700多种不同的植物和动物。而如今这个大湖——也是世界上最深的湖(1 740多米深)——湖水已经被一家化工厂的废物污染了。

1989年，一艘油轮在坷拉斯加西北海岸的海面上触礁，35 000吨汕倾入大海。这是历史上最严重的事故之一。34 000多只鸟和10 000多头动物死亡，4 800平方公里的海洋受到污染。
