RSM419: Green Paper - Overpopulation
Global population has already reached a record high of 7 billion people as of 2011. While it continues to grow at an estimated rate of 1.1%1 annually, it becomes a worldwide society concern when it comes to the topic of whether the world can continue to sustain such high numbers. Like a ripple effect, this adverse pattern in population has a direct impact on other major environmental issues such as resource depletion, waste excretion and pollution, etc. To highlight why this matter is of importance, this paper will briefly examine the causes and effects of overpopulation, and specifically discuss on possible solutions to this global environmental issue.
As a result of rapid advances in the science and medicine area, it is evident that there has been an exponential increase in birth rates and a steady decline in mortality rates over the past decades. Both of which are fundamental causes of the current overpopulation issue. Another major factor is the lack of education amongst people. Specifically, people are not educated on the importance of preventing population from growing excessively, nor are they aware of the downsides to overpopulation. Hence population size is not properly controlled. Although an increase in population is equivalent to an increase in human resources, which is beneficial for the world economy. Population growth directly causes numerous other environmental issues. Firstly, more people require more resource usage. This sets off an imbalance between natural resources usage and replacement, which directly leads to a natural resource depleting trend. Specifically, forests are being cut down at a dramatic speed to serve demands in wood and land. More people means more food consumption, which give raise to high demands in food. Although there are continual efforts to prevent overfishing, it is evident that the issue is still existent as “over 70% of the world’s fish species are either fully exploited or 2...
