问题     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 for a modem way of life. We make "increasing industrialization" our first aim. So we can often ready to offer everything:clean air, pure water, good food, our health and the future of our children. There is a constant(不断的) flow of people from the countryside into the cities, eager for the achievements of our modem society. But as our technological (技术的) achievements have grown in the last twenty years, pollution has become a serious problem.
    Isn’t it time we stopped to ask ourselves where we are going — and why? It makes one think of the story about the pilot who told his passengers over the loudspeaker(扩音器) :"I’ve some good news and some bad news. The good news is that we were making rapid progress at 530 miles per hour. The bad news is that we are lost and don’t know where we’re going." The sad fact is that this becomes a true story when speaking of our modem society.
