范文 Air Pollution

We all know that clean air is important to good health. Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air. If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities.

Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things. Every year these factories pour millions upon millions of tons of smog into air. Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now. Once out on the streets, they will take in fresh air and replace it with poisonous gases.

Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes concerted efforts, the day will come soon when people will take in only clean air. Then, the sunlight will no longer be blackened out by smoke and soot.

Global Shortage of Fresh Water

Many people believe that the world’s supply of fresh water will never be used up. They think that fresh water comes from such a variety of sources such as rain, river, and well, which is always sufficient for use. Such an opinion leads to a shocking waste of water.

As a matter of fact, the earth is short of fresh water. Furthermore, with the rapid growth of the world’s population, the rising demand for water by industry, and the serious pollution of our surroundings, the world is facing the danger of running out of fresh water. Actually, in some big cities, fresh water cannot meet the daily needs.

Therefore, to find new ways to save water is an urgent task. First, we should pass strict laws to control any waste of water. Second, scientists must work even harder to purify sea water and polluted water, and try to find substitutes to reduce the use of fresh water.
