Our surrounding(周围) is being polluted faster than nature and man’s present efforts can’t 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 solve this problem? The fact is that pollution is caused by man—by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are always ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from countryside to cities, eager for the benefit of our modern society. But as our technological 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 airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.
