What are the major causes of human overpopulation?
According to some experts from the University of Michigan, in their webpage “Human Populations” they found that the factors affecting global human population are very simple. They are fertility, mortality, initial population, and time . . . The stabilization of population will require a reduction in fertility globally. In the most optimistic view, this will take some time. They also explained that The current growth of population is driven by fertility. The picture shows how total fertility rate is a strong function of region. It can be readily seen that the more developed countries, the north countries, have lower fertility rates than the less developed countries, the South countries. The fertility rates in the developed world are close to replacement, while the rates in the developing world are much higher. Thus, population growth and level of development are clearly linked. Global Total Fertility Rates, 1990-1995 Fertility is largely controlled by economics and by human aspirations.
