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.

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.[由wwW.HaoZuoWen.com整理]

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 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.
