Quest for optimum human population per nation

The world is being saturated with population to a point where its life‐support systems may be in danger of losing their ability to maintain environmental stability. Thus, there is an urgent need for scientists and decision makers to develop working models in which information about the population, resource exhaustion, and pollution of each nation is contained. The criteria for determining optimum human population are reviewed, and a bionomic model that incorporates the complex web of economic and political systems within an ecological framework is presented to solve the problem of how large a population each nation should have.
