Progress in science and the improvement of living conditions have led to the rapid growth of the world population. Modern medicine, 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 result, the world population has increased so rapidly that it has now exceeded 6 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, limited productivity and scarce world 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 fast population growth and carry out a family planning programme. Only by adopting effective measures, can human society develop steadily and have a bright future.

科学的进步和生活条件的改善导致了世界人口的迅速增长。例如，现代医学使婴儿健康成长和人们长寿的可能性成为可能。随着生活条件的改善，特别是在农村，人们往往有更大的家庭。结果，世界人口增长如此迅速，现在已超过60亿。
但是人口的过度增长对人类社会的生存构成了威胁。大量的人口需要大量的食物供应和住房空间。然而，有限的生产力和稀缺的世界资源很难满足日益增长的人口需求。因此，从长远来看，世界人口的过度增长只会损害人类。
为了保障人类社会的稳定发展，人类必须认识到人口快速增长所带来的后果，实行计划生育。只有采取有效措施，人类社会才能稳步发展，前途光明。
