Overpopulation is a serious problem, which refers not only to each family but also to the whole nation.
In a large family, the parents can not earn enough money for their many children. The children themselves are not well nourished and educated by their parents. It’s hard for these physically and mentally handicapped young people to become qualified citizens to serve their country. Besides, the mothers who have given birth so many times are certainly unlucky in their lives.
In a wider range, our government can not deal with such a serious problem while the country is still underdeveloped. If the population increases uncontrollably, the government will not be able to provide enough food, home, work and education for so many people at the same time. As a result, the people’s life become worse and worse.
To ensure happiness, each married couple should have only 2 children.
