Why didn't whites colonize Africa on a large scale?

This is related to the local climatic conditions, natural environment and social structure in Africa. Generally speaking, the cost of large-scale white colonization of Africa is too high.

First, the bad weather conditions are hard for white people to accept. Africa is famous for its harsh climate. The largest Sahara desert in the world is in Africa, with hot weather and little rain. Most indigenous people in Africa are black. Except for some places in North Africa, the most striking characteristics of blacks are curly hair and dark skin, which are physical hardware facilities evolved by human beings to adapt to the environment. Curly hair can help the scalp to dissipate heat, and dark skin can resist ultraviolet rays and avoid the interference of skin diseases. This harsh climatic condition makes it difficult for whites who have been living in Europe with relatively normal temperatures to adapt, especially in the Nordic countries. Besides, after Columbus's voyage, isn't it good to colonize the rich and comfortable American continent?

Second, the natural environment is full of dangers and the cost of colonization is too high. There are many wild animals on the African prairie. If you live there, you will be attacked by wild animals if you are not careful. That's not a paradise for human existence, but a law of nature? Survival of the fittest? The best test center. In early Europe, there was no developed medical technology, and limited by religious culture, their keen surgery could not develop in society at all, while ignorant medical methods often caused innocent deaths of patients, such as bloodletting therapy, and a little carelessness was blood death. If Europeans, regardless of the obstacles of natural conditions, resolutely let a large number of people immigrate to Africa, it is to die.

On the one hand, the constant attacks of wild animals will make the colonists exhausted. How can we have time to develop colonial culture and improve social economy? On the other hand, if some insect and ant bites in Africa cause a plague, then Europe, which probably experienced the Black Death, is about to face a catastrophe. Even at this moment when the medical level has made great progress, viruses such as dengue fever and Ebola, which are prevalent in Africa, are still rampant, and medical personnel in various countries are still tied behind and have not developed a cure. Europe has a small population, so they dare not take the risk, so there is no large-scale immigration, but there must be a small number of immigrants in the early stage? A mouse? .

Third, there are too many foreign tribes in African society to bear the management costs. There are dozens of countries in Africa, large and small. It used to be divided into hundreds of tribes, and the population was not small. In order to colonize Europe, the first thing is to unify the tribes and form a whole, so as to better implement the colonial strategy, just like early Britain? Unification? India. These tribes have a large number of people, a large population, language barriers, isolation and wonderful culture. After all, there is? Cannibalism culture? Moreover, the overall physical quality of the people is good and difficult to discipline. Each of the above items has increased the management cost of colonization, and a slight relaxation will lead to the counterattack of blacks. Although whites gave up the large-scale colonization of Africa, they did not give up the plunder of African resources and labor, as evidenced by the wanton exploitation of African mineral deposits and slave trade.
