overpopulation if not properly managed can lead to so many negative effects on the development of a nation as a result of using the limited available resources for a population that is more than such resources. But in reality, I think if we had good leaders, overpopulation wouldn't even become a subject to be bothered about,

The problem is that we concentrate on the development of a small fraction of our country leaving other part behind and you now find a situation where everybody want to congest the developed part while the local areas have a very small population of people.

If we diversity our developmental strategies and site companies in areas that is less crowded, it would bring development to those part and bring more people in the long run thereby reducing the population of people in urban areas.

I think most of these supposed over populated nations are not all that populated but rather, they are just congested at a particular area.
