The government of India encourages married men and women to be sterilized so they cannot have more children. In China, families can be punished for having more than one child. Both of these countries have very large populations, and if the number of people continue to increase, there will not be enough food, 5 houses or jobs for the people. As a result, India and other populous countries are following a family-planning policy-they want families to limit the number of children they will have. Teachers, doctors and social workers are explaining to the people why they should have fewer children by using birth control methods such as contraception and sterilization.
