Zero Population Growth

Zero Population Growth (ZPG) refers to a situation where the number of people in a population remains stable over time. This occurs when the birth rate equals the death rate, meaning that each couple has enough children to replace themselves, typically about two children per family. ZPG is significant for managing resources and ensuring environmental sustainability. It aims to prevent overpopulation, which can strain resources, infrastructure, and the environment. Advocates of ZPG often promote family planning, education, and policies that support smaller families to achieve a balanced population that can be sustained by the Earth's resources.
