【正确答案】Population Problem
The problem of a rising world population is largely the result of improved life and medical care, which have lowered the death rate and at the same time raised the birth rate. Besides, the birth control program is not well carried out. Consequently a large population appears.
There is growing awareness of the problem of a rapidly increasing world population and there is also a growing realization that food production can not keep pace with these increases, the result is that in some countries people are already starving to death while some other people suffer from malnutrition.
The most important thing for us today is to realize that we can not go on expanding human population forever and we must take urgent measures to get it under control.
