Question

Human population growth and its impact on environment​

Answer 1

Answer:

Population growth can be defined as an increase or decrease in the population size of living species including human beings. Human populations are also subject to natural process of birth and death. There has been a rapid increase in the worlds human population over the last few decades (UNFPA, 2011). Unless urgent steps are taken to control population, serious problems can arise like environment damage and limited availability of food resources. Continuous population growth can be problem and therefore it is important to understand how we can manage population growth for the benefit of all. Human beings have tried to make food resources available for all the population in many ways. Starting from the industrial revolution, advances in modern medicine, and green agriculture revolution have all made us self sufficient so far. However such technology development cannot go forever and therefore unless we manage population a day may come when all resources will be finished.

At present there are two school of thought for the theories on population growth. The first is the pessimistic view developed by Reverend Robert Malthus, a British scholar who believed that the resources available will not be sufficient for human beings if human population is not controlled. The other theory is the optimistic view developed by Julian Simon who believed that humans can manage the issue of population because of their knowledge and skills. Therefore this paper will discuss these two theories for population growth and their effect on the resources and environment of the earth.
