Before we move on to overpopulation problems, we need to know about the various factors that are responsible for this incessant rise in population. Significant improvement in quality of life and basic health services has resulted in decline in death rate, and at the same time has caused an increase in the birth rate. Continuous migration of people from underdeveloped areas to developed areas has triggered an unnatural growth in population in developed areas, thus, putting immense pressure on available resources. Our failure in understanding the problems caused by overpopulation in urban areas is reflected in unplanned growth of newer towns and cities. More importantly, a look at the projected population growth is even more horrendous, which in itself stresses on the fact that we are not learning from our mistakes.

Problems Caused by Overpopulation
Overpopulation problems refer to a series of interwoven problems which are basically caused due to population explosion. The worst thing about these problems is that they act as major hindrances in the process of development. Though restricted to the urban areas as of now, these problems have already begun and it will be just a matter of time before they engulf the entire planet.
Scarcity of Resources
Available resources will not be sufficient to meet the demand of rising population. Only 3% of water on the planet is potable, so overpopulation problems will start with the lack of drinking water for millions of people across the globe. Land available for agricultural production is also shrinking, which means the amount of crop produced will decrease with time. If population increases and crop production decreases, a large part of population will be left to die of hunger. In fact, Thomas Malthus had predicted this problem of food shortage due to rise in population two centuries ago through his theory of population. Scarcity of resources will not just be restricted to food...
