求关于保护海洋的英语文章,
简短一点,
简短一点,
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

Man and His Environment(人和环境)
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.
