We live in a finite world, and the population just cannot grow without limit.
To this effect there can be control over it from government. But by creation it has been given to man to occupy and enjoy the fruits in it. The challenge is that despite population, bad leadership is the problem for Africa. Lack of proper planning is causing some of the food shortages. Some buildings are erected on land there are designated for agricultural purposes and by this it amounts to imbalance in planting processes. There is suppose to be rotational planting where some land are left for a certain time to regain nutrients but they are continually planted on because there are no adequate space. This will lead to low production of crops.
