Population Control
Progress in science and the improvement of living conditions have led m the rapidgrowth of the world population. Modern medical science, for example, has made it possible for babies to grow up healthily and for people to live longer.With improved living conditions, particularly in the countryside, people tend to have larger families. As a resuit, the world population has increased so rapidly that it has now exceeded 5 billion.
But the overgrowth of population presents a threat to the existence of human society. A large population demands a great deal of food supply and shelter space. However,the limited productivity and scarce natural resources can hardly meet the needs of the ever-Increasing population. Thus in the long run, the overgrowth of the world population will only harm mankind.
To guarantee the steady development of human society, mankind must realize the consequences resulting from a fast population growth and the importance of carrying out a family planning programme. Only by adopting effectual measures can human society de velop steadily and have a bright future.
