Population and Birth Control
Mankind is feeling greater pressure from the expanding number of people. The earth can never be expanded. Nor are there endless sources of food and clothing. Yet people are being born faster than they die. In the next forty years， the world population may double. How can so many people be fed？ What is worse， there is danger that someday mankind will have only standing room.
Birth control should be a basic policy in our country. China has the biggest population in the world. With a high birth rate， the production of grains and goods will be unable to meet the need of the people. To raise people's living standard， we must practice birth control.
There are disadvantages of a family having more children. First of all， as the parents have only limited income in general， they cannot give their children a good breeding in food ， clothing and shelter， let alone education. Second ， child rearing will exhaust the parents， leaving them no time and energy for their work. Last， having more children will increase the burden of the society.
