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 bees 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?
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.
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.
THE EARTH,our dearest mother--BUT,my friends,do any of you have considered how serious the problem will be when the earth is polluted,the air is not fresh,the forest is not flourishing?The environment pollution exist everywhere,the earth will lose its luster noon.my friends,shold we still keep insensible?our earth mother is not smiling anymore,doesn't it do something to us?Let's moving,my dear classmates,carry out environmental protection with a trifle to make the earth a pure land,and,let it hold a charming smile!
地球，我们最亲爱的母亲。但是，当大地被污染，当空气不再新鲜，当森林不再茂密，亲爱的朋友，您想过吗? 这是一个多么严重的问题!污染环境的问题随处可见，地球母亲即将失去往日的光彩。朋友，请问我们还能够无动于衷吗?朋友们，对于污染环境的问题 随处可见 ，母亲不在微笑。难道我们不心痛吗? 亲爱的同学们，让我们行动起来，从小事做起，展开环保活动，还母亲一片净土。让我们的母亲从新拥有一个迷人的微笑。
Man and His Environment
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.
The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides， forest destruction ， water and air pollution result in decrease of planting land and unpleasant weather.
Serious as the problem seems， we can come up with some measures to deal with it. First of all， the authorities should adopt the policy of "sustainable development"， and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.
What' s more， every citizen should realize the seriousness of the problem and make concerted efforts to protect our environment. In addition， planting trees helps improve and beautify the environment.
我们生活的世界正变得越来越难以忍受，因为对环境的破坏。 禽流感和SARS的是两个典型的例子，对环境的破坏，可能危及自己的生命。 此外，森林破坏，水和空气污染导致减少种植业土地及不愉快的天气。
严重的问题，看来，我们可以得出一些措施来对付它。 首先，当局应该采取的政策是"可持续发展" ， 法律和有关环保工作应该要付诸实施，执法不严，正如我国政府一直在做的事。
何况， 每个公民都应该明白问题的严重性，并共同努力，为保护我们的环境。 此外，植树有利于改善和美化环境。
The Yangzte River is the longest river in China. And it's important and helpful to us Chinese. But these days the Yangtze River is bringing us serious floods.
Many villages were destroyed by floods. The floods made hundreds of millions of people lose their homes, relatives and friends. Many children can't go to school as usual .Now the foods have drawn the attention of the whole world. People from abroad have offered their help too. In China, millions of soldiers are busy fighting against the floods. They are working very hard. Many of them have lost their lives in their attempt to save the villagers.
Though we can't help them to fight against floods, we should help them to rebuild their homeland. We can present them our pocketmoney and clothes. I believe most of the people will return to their homeland in the near future.
Protection of the Environment
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.
Save the Wild Animals
Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.
In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.
Only if we human beings take some drastic measures can wild animals be preserved.
The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earth's surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.
However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?
We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.
