Answer:
political instability
Explanation:
Sub-Saharan Africa is one of the most troublesome regions in the world. The region has lot of problems on pretty much every level, and one of the major issues is the destruction of the environment at a very fast rate.
Lot of funding is provided for the countries of this region, and lot of organization operate in it in order to help the people to solve the environmental problems, for the good of both them and the environment. Unfortunately, big portion of the governments are still very corrupt, the countries have very bad organization, and para-military organizations function in them, all of which contributes to creating chaos and instability in them.
The instability and the safety issues because of it, stop the people to do anything in particular when it comes to improving the environment, and with it their lives, as they are scared to move into certain areas as they might end up dead, like it is the case in Nigeria and the territory controlled by Boko Haram.
There could be different answers towards this question depending on how you view the current situation. This is my opinion towards the answer.
Yes, the world currently is over populated as the Earth cannot produce enough resources to sustain human activity in the future hundred years. According to researches, approximately 3.1 Earths will be needed to provide sufficient resources for the most developed city.
Currently, there are 7.5 billion people living on Earth and some places are already facing problems of the lack of natural resources like water and food, and have to rely on import to sustain civilians lives. This is often the result of the exhaustion of resources such as overcultivation to satisfy the need of such large population. We can therefore see that the world is indeed overpopulated.
Hope it helps!
