Zero population growth refers to a demographic balance where the number of births equals the number of deaths, leading to a stable population. There are several synonyms for the term, such as demographic equilibrium, population stabilization, and sustainable population. These terms reflect the idea that maintaining a stable population is crucial to ensuring a sustainable future for the planet. Achieving zero population growth requires a focus on reproductive health, access to family planning, and education on sustainable living. By promoting these values, we can create a better future for ourselves and our planet by ensuring that our population does not overburden the earth's resources.
