PERSPECTIVES ON POPULATION GROWTH Based on the current trend‚ there will be a total to about 9.2 billion people on the earth by mid-century‚ fuelled by the birth of 220000 children a day and falling mortality rates (Population Institute‚ 2014). This estimate raises questions about the future of humanity and the planet we inhabit. The debate about an optimal size for human population is one that has waged over the years. The question is fundamentally about sustainability; whether the resources that

demographic theory In the middle of the twentieth century‚ demographic transition theory became the dominant theory of population growth. Based on observed trends in Western European societies‚ it argues that populations go through three stages in their transition to a modern pattern. Stage one (pre transition) is characterized by low or no growth‚ and high fertility is counterbalanced by high mortality. In Stage Two (the stage of transition)‚ mortality rates begin to decline‚ and the population grows

His An Essay on the Principle of Population observed that sooner or later population will be checked by famine and disease. He

suggests that demographic dynamics is the change in population in terms of size composition‚ age structure‚ and urbanization. This includes the causes and consequences of migration‚ fertility and mortality. These dynamics are different from the past since each and every country experiences changes in terms of living condition‚ number of people born and people who died in that particular time.

factors. The Malthusian Trap is a theory that argues that when the population growth exceeds the agricultural growth; the food supply becomes inadequate for feeding the population at one point leading to starvation and famine (Rittenberg & Tregarthen‚ 2012). The theory was originally presented by Robert Malthus in an essay on the Principle of Population in 1798‚ arguing that food supply expansion is linear whereas human growth is exponential. Malthus‚ however‚ argued that the power of population is indefinitely

A neo Malthusian is somebody of Malthus beliefs Neomalthusians on population growth and control the neo-Malthusian theorists may be presented as a splinter group. Essentially they agree with Malthus that control of population is inevitable. However they disagree with Malthus that factors like war and famine are the key to population control and reject such simplistic notions. Instead they promote a number of ideals for example planned parenthood as a method of population control. Mustapha‚ Nasser

argued that high population and low resources created a situation in which a crisis was inevitable. Certainly‚ populations were high and prices for basic foodstuffs had risen in the first half of the century. However‚ populations were already beginning the decline before the Black Death. A Malthusian crisis should thus have occurred earlier. Further‚ even after populations had collapsed in the first wave of pestilence‚ subsequent plagues continued to rock Europe and demographic recovery did not occur
