Our surroundings are being polluted
faster than ever and it seems that people cannot prevent it. Time is bringing us
more people, and more people will bring us more industry’, more cars, larger
cities, and the growing use of man-made materials. What can explain and settle this problem The fact is that pollution is caused by man—by his desire (欲望) for a modem way of life.

There is a constant flow of people from the countryside into the cities, eager for the achievements of our modem society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
