【正确答案】Birth Control
Almost everyone expresses concern about the problem of population. It is estimated that at the end of this century, the population of the world will reach 7 billion.
Why has this huge increase in population taken place? Firstly, in many developing countries, family planning hasn't been paid-special attention to until recently. The problem is too serious to be solved in a short time? Secondly, the progress in science and improvement of living conditions has led to the rapid growth of the world population? For example, modern medicine and improved living conditions make it possible for babies to grow up healthily and for people to live longer.
To change this situation, people have to take active measures. Men and women should be urged to get married late and practice birth control. Moreover, each couple should have no more than one child. The exceeding childbirth must be punished. Only in this way can population problems be thoroughly solved.
