The Malthusian Theory is an economic theory suggesting that population growth will eventually outstrip the planet's resources, leading to widespread famine and other ecological disasters. While this theory has fallen out of favor among some economists in recent years, there are still many alternative ways to describe this phenomenon. Some of these synonyms include neo-Malthusianism, sustainable development, and population control. Additionally, many theorists have expanded upon the original concept of the Malthusian Theory to encompass broader environmental concerns, such as climate change and resource depletion. By exploring these various synonyms and related concepts, we can gain a more comprehensive understanding of the complex relationship between human populations and the planet they inhabit.
