The current world population statistics indicate figure above seven billion. A comparison of the same figure over years of economic transformation and industrialization reveals a steady increase in the general population. This paper analyzes overpopulation as a leading global challenge facing humans on earth. The discussion targets to explore causes of overpopulation, effects of overpopulation and solutions to overpopulation.

Various population data of the world’s nations will form the basis of argument on the topic. The presentation will also feature various population conditions in regards to geography as a course study to address the crisis “The population of Earth in 2014 is estimated to be 7.2 billion, but people are not evenly distributed across the landscape” (Dahlman & William, 210).
