Answer:
B. sub-Saharan Africa
Step-by-step explanation:
Sub-Saharan Africa is one of the most, if not the most troublesome regions in the world, whichever aspect do we look at it. The region is very poor, and the economies in very bad condition, thus they do not generate lot of money. The agriculture is still primitive, with the slash-and-burn method still being used, contributing to destruction of the environment and total degradation of the soils. The food is constantly in higher demand than what is produced, with the main reason being the very rapid growth in population, which can not be caught by the slow growth of the agricultural production.
