The topic of this essay, overpopulation, refers to a situation whereby the number of people inhabiting an area exceeds the resources available for living. This problem of overpopulation is becoming an ever prominent concern in contemporary society and has been discussed by a number of commentators, such as Bellisari (1994), and Buzzle (2008). The actual number of causes, and scale of effects, of this phenomenon may be vast; however, this essay will focus on what are perhaps some of the more major ones. This essay will first discuss the possible causes of immigration and increased birth rate respectively, before moving on to the potential effects of widespread disease and food or water shortages.
