man is finding himself confronted with more and more problems which threaten his existence on this planet. for example, some resources are beginning to be exhausted. many diseases are getting difficult to be cured. various kinds of pollution are becoming worse and worse. moreover, population explosion is always on the rise...

　　therefore, there comes the problem: will man survive these problems?faced with so many problems, pessimists hold that man is destined to die out. their reasons are as follows. with population explosion, food will be scarce; space will shrink; resources will be used up. moreover, pollution will threaten our health; incurable diseases will endanger our lives... obviously, man has only one way out—complete destruction.

　　admittedly, these people have their reasons to think in this way, but i don`t think they are altogether right. i believe that man is bound to overcome these difficulties and survive a into the future because man is endowed with wisdom. with this wisdom, he came up with solutions to problems he came across in the past. with this wisdom, he will surely work out solutions to the problems which will arise in the future.
