Once upon a time, 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 these seas, 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 recycle 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.

Environmental problems are being more and more serious all over the world.For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence. The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will be better and better.

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 reservoirs out of rivers for irrigation purposes or hydro electric power. Man has also modified the face of the earth by draining marshes, sand 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 gases come out of the exhausts of motor vehicles.Smoke from factories pollutes the air of industrial i zed areas and the surrounding area soft he countryside。The pollution of water is equally harmful。The whole eco logical balance of these a is being changed and industrial wastes have already made many rivers life less。Now environmental protection is more pressing than ever before。As we know，mass i vedestruct i on of environment has brought about negative effects and even poses a great threat to man's existence。In difference to these problems will mean mitting suicide。Therefore，effect i veme a sures should be taken and laws passed to con serve environment。Otherwise，man is certain to suffer from the serious consequences caused by this lack of care for his living surrounding s。

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 transport at once 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 clean energy, like energy from the wind and solar.
