摘要：Sub-Saharan Africa is still considered a land semi-isolated from the rest of the world, without many natural harbors or navigable rivers, or inland islands and seas, with 16 states that do not have access to the sea and D.R. Congo with limited access that is difficult to achieve. All these states that can be considered the Heartland of Africa, have now reached a total population exceeding the US population, will exceed the population of continent Europe by 2050 and will have a population similar to the continents of America and Europe taken together by 2100.
