North Africa, as a region, is one of the most inhospitable places on Earth for living. The main reason for this is that the region is almost entirely dominated by desert and semi-desert. The number of rivers and streams is very small, with some countries have none, some one, some not more than fingers on one hand. The soil is not good for agriculture apart from the very few places along the water bodies, the temperatures extremely high, and sand storms always being a danger.
