The term overpopulation refers to the concept that the number of humans who rely on the resources necessary for life is significantly greater than the amount of resources provided by the earth[3]. Overpopulation can be caused by a combination of factors. Reduction in mortality rate, better medical facilities, depletion of valuable resources are some factors that have contributed to overpopulation [3]. Our planet is beginning to face the effects of population growth. At the current annual growth rate, the population increases by 80 million people every year. This increase will result in 9 billion humans on earth by the year. 2038
