Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.

Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.

We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are

still put into rivers.

We know that if the population continues to rise at the present rate, in a few years, there won't be enough food.What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.

Our natural resources will last longer if we learn to recycie them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.


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 you know, 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.


The area of desert in the world is growing every year. Many parts of the world which once had large populations and produced plenty of crops, have become deserts. Dunhuang in China, deep in the heart of the Gebi Desert, was once a great city.

Cattle are one cause of the problem. In good years, famers increase the numbers of their cattle. Then one year, the rains fail to come. The farmers do not want to kill any of their cattle, so the cattle eat ail the grass and anything that grows on poorer land. If this continues for several years, the grass never grows again and the land becomes a desert. One suggested answer is for farmers to limit the numbers of their cattle.

Another problem is that good soil is gradually lost. When trees are cut down, there is nothing to hold the soil in place on the hillside. So when if rains, the soil is washed down the hills and into the rivers. Strong winds can also blow away the valuable soil that lies on the top of the fields.


Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reserviors out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.

However, man's changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.

Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to man's existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise,man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings.

Over 70% of the Earth’s surface is water; water is obviously the most precious natural resource that exists on our planet. Without water, life on Earth would be non-existent. Water is the lifeblood of the environment, essential to the survival of all living things-plants, animals, and human. Although we recognize this fact, we disregard it by polluting our rivers, lakes, and streams. Afterward, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate, and our drinking water has become greatly affected. In order to fight against water pollution, we must understand the problems and become part of the solution; we also need to do everything possible to maintain its quality for today and the future.The government alone cannot solve the entire problem; it’s up to us when it comes to the problems we face with our water. In your home, correctly dispose dangerous household products. Keep paints, used oil, cleaning solvents, pool chemicals, and other dangerous household chemicals out of drains, sinks, and toilets because many of these products contain harmful substances. In your yard, recycle used motor oil. Avoid pouring waste oil and resist the temptation to dump wastes onto the ground.These are just a few of the many ways in which we, as human have the ability to combat water pollution. If these measures are not taken and water pollution continues, life on Earth will suffer severely.



Environmental problems are as big as not for individual country or individual people to address. In other word, we have reached the stage that environmental problems be solved for international view. To what extent do you agree or disagree?

In recent years, many nations have become more aware of the environmental issues each nation faces, such as air and water pollution. The question is, are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of becoming an international problem needing international cooperation to resolve.

Because of the differences in environmental policies, resources and technology, international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology. By pooling international resources and technology to address the environmental problems, the disadvantaged nations are provided the assistance needed. Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole.

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection. In order for international cooperation to occur and succeed, the nations of the world must submit themselved to international standards and supervision by an international commission elected by the participating nations of the world. All members must agree to abide by the standards established.

The environmental issues facing each country are not unrelated to the well being of the rest of the world. The impact is long term and international in scope. Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole, depletion of the ozone layer, water pollution, air polution, etc., the environmental conditions of the world will deteriorate to the detriment of every nation, not just those that ignore or lack the resources and technology to resolve their individual environmental problems.

As part of the same planet, it is the responsibility of each individual and nation to protect the global environment. Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment.


Some people believe that the Earth is beingharmed(damaged) by human activity. Others feel that human activitymakesthe Earth a better place to live. What is your opinion?Usespecific reasons and examples to supportyouranswer.

People have been living on the Earth for thousands of years.Humanactivity influences the Earth. Some people believe that theEarth isbeing harmed by human activity. Others feel that humanactivitymakes the Earth a better place to live. In my opinion, theearth isbeing damaged by human activity. There are manystatementssupporting my opinion.

Human activity has damaged natural environment and almostexaustednatural resources. Modern industry needs more and moreresources,including minerals, fuels and water. So we confront ofthe seriousproblems such as the lack of fuels and water.Ecological balance isdamaged because factories occupy many placeswhere animals andplants live. More and more buildings areconstructed and forestsbecome less and less. If we cannotrecognize these problems andsolve them soon, we would finally losethe environment suitable forour living.

An other serious problem is the green-house effect.Humanactivity decreases forests and increases the usage of fuels sothatthe gas of carbon dioxide is output more and more and there arenotenough plants to absorb it. The green-house effect is moreobviousand more sensible these years. Due to the effect, icebergsin thesouth polar and north polar melt and the sea level becomeshigherthan before. I am worried about the cities nearby the sea andhopescientists find an effective method to eliminate thegreen-houseeffect.

Although we have advanced machines and our life seemsmorecomfortable than before, we have less chances to approachnaturesand less spaces to act. The cities become bigger and if wewant tohave a picnic with our friends, we have to drive a longdistance tofind a natural place. In fact, the spaces of humanactivity arebeing damaged by the skyscrapers and factories.

From the above statements, we can conclude that humanactivitybrings the Earth many damages. Fortunately people haverecognizedthe point and I believe that the Earth will become abetter placeto live with our ceaseless efforts.


White pollution persists

WE'VE been hearing and talking about it for a fairly long time curbing what has become known as “white" pollution. But still we are using the white polystyrene (PS) foam food containers and other disposable plastic products which largely make up this form of littering.

Miandianwang a well-known local fast-food chain is still handing out takeout food in these PS foam containers even though they should been phased out before December 31 2000 under a Central Government decree. One of the waiters said in its outlet on Hongli Road on Monday that they are going to switch to environmentally friendly containers “some time in the future".

However the Miandianwang outlet in Sam's Club which is affiliated with Wal-Mart is offering take-out food in light brown containers which are biodegradable. Liang a clerk with Sam's Club told Shenzhen Daily yesterday that the club required the Miandianwang outlet to do so in its contract.

According to Liang all the departments in the club switched to biodegradable containers during the Spring Festival holiday.

Zhao Hua with the energy division of the Shenzhen Municipal Economic Development Bureau one of the five municipal government departments involved in the curbing of white pollution in the city said on Monday that large companies and retailers like Wal-Mart and Vanguard have responded to the decree by switching to biodegradable containers. But she admitted that is just the tip of the iceberg in the seemingly endless war on white pollution in the city.

Zhao's bureau has met with four other relevant departments on several occasions. What they produced is not a feasible solution but an echo or rewording of the Central Government decree according to Luo Wei from Shenzhen Municipal Legal Affairs Bureau who is responsible for reviewing this “echo". The ”echo" has now been passed on to the municipal government which is expected to announce it formally in the near future. But Luo said she's not sure if this rewording can play a significant role in eliminating white pollution in the city. “We don't lack laws regulations or decrees. The real concern is the effective enforcement of these laws or regulations" said Luo.

Zhao Hua admitted that cities like Shanghai and other coastal cities which are sensitive about their image as tourist destinations are doing a better job in this regard. “Shanghai is said to have produced a very detailed handbook on how to carry out the curbing work and Hainan has even banned disposable foam slippers in hotels" Zhao said.

Liu Guanqing president of Shenzhen Xunbao Investment Development Co Ltd a local manufacturer of biodegradable food containers was very eager to hear the municipal government's decision on the matter. “Since early this year I've seen orders fly in. I'll expand production once the government announces its stance on the issue."


Cars and Air Pollution

Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly.

On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.


Important to save water

Water is a kind of liquid. It has no taste or smell. It is transparent, too. Water is useful and is important to us. Why? For example, we use water to water the plants. We use water to wash our face or to have a bath. We drink water or we will die…Water is also very important for China. There are 2.8 hundred millions of steres of water in China, but everyone can only use 2300 steres. It is only twenty–five per sent in the world.

Not too long ago, there was a man called Jacques Cousteau. He loved the beautiful colors, and the beautiful fish in the sea. However, when he returned some years later, the colorful coral reefs were dead and grey because the factory near the sea poured waste water into the sea. Jacques Cousteau decided to tell people how important it was to save the environment under the sea. He started the“ Cousteau Society ” to help protect life in the sea. Now there are over 30000 members all over the world. Since water covers most of the earth, Cousteau knew that we should keep the sea clean. We should not litter the sea, and should clean up the dirty parts. As water is very important to our environment, he encouraged everyone to take part in protecting our lakes, rivers, sea and ocean.

There are still a few people who are not protecting the water now in the world. For example, some factories pour waste things into the rivers, lakes or into the sea near by. The water there has become very dirty and we can’t use them at all. Although there are seventy–five per sent of water in the world, we can only use fresh water, that there is only a little. So we should use little water when we need to use it. For example, I do not use too much water when I am washing my face or having a bath… It is important for us to keep the water clean. You may ask yourself, have I ever poured or thrown dirty things into the water? If your answer is “No”, that means you have already helped to protect the environment. It is our duty to protect the environment. You may ask yourself again, have I ever helped to clean up the water? If your answer is “Yes”, that means that you have already done something useful to improve the water. If we use up all the water, it is difficult for us to get it from anywhere, including the universe. It is terrible to think that people are too thirsty to live! I believe, that if everyone helps to protect the water, the water must be protected. You do not want to “kill” your son or your grandson, do you? So now let us to protect the water! Please don’t let the last drop of water on the earth is we human’s tear!
