It is widely believed that fresh water will never be used up due to its rich resources such as rain, rivers and wells. In fact, such belief is unfortunately wrong and possibly dangerous. As is depicted in the picture, we are facing serious shortage of fresh water, especially in the northern part of China. The land in some areas has become barren and there is no water coming from the pumps. Definitely, the picture reminds us of the serious situation we are confronting.
Short as it is, people still waste it. With the growth of population and industry, the amount of fresh water in use is also growing rapidly. It is estimated that if not controlled, fresh water will be used up by the next century. Another dangerous factor is the water pollution, which aggravates the seriousness of fresh water shortage.
It is no use only being aware of the shortage of fresh water. It is never too late if we act right now. The first important measure is to protect our water resources form being polluted. Educating people to save water in daily life is of similar significance. Techniques such as recycling waste water and converting sea water into drinkable water are especially needed in dry areas. It is only when these measures are put into practice can the shortage of fresh water be solved.

Air pollution, which can be seen in many parts of the world, is one of the serious problems the world’s people are facing today. As is indicated from the picture, the poisonous gas coming from the factories, automobiles and houses pollute the air without which cannot live. There is no denying that many people as well as scientists have been aware of dangers air pollution brings to people.
The first category of dangers it has brought is the harm to our health. Nearly everyone knows that serious air pollution irritate our eyes, causes us to cough and makes us get more serious diseases. Air pollution is not only dangerous to people but also detrimental to our surroundings and our daily life. It corrodes our building, damages crops and forests and causes both airplane and auto accidents because it cuts down visibility. Furthermore, the pollutants in the air may travel through the air with wind; as a result, air pollution can spread from city to city, even from country to county. So air pollution is really a global problem.
As can be seen from the above dangers, air pollution cost our human beings a great deal of money. Therefore, it must be worthwhile to spend more money and efforts on air pollution control.
