Population education is important in countries that are in danger of overpopulation because it informs students on population trends and aims to promote having smaller families. Educating students on population dynamics was introduced in many Asian countries during the 1970s.
Human overpopulation occurs when the amount of people living in an area outgrows what the environment can sustain with food, water, living space or other vital resources. The amount an environment can sustain is known as its carrying capacity. In areas of the world where the carrying capacity is threatened or exceeded, education may encourage young people to grow up and have fewer children. Understanding the danger is thought to help reduce the problem.
