Why is Africa so important to the industrialized world? The reason is that Africa has a lot of natural resources as well as human capital. Solar energy and water are two such resources but also the rapidly growing population and the expanding market. Having exploited much of the resources present in industrialized countries and having cutthroat competition in rather saturated markets, businesses in industrialized countries look to Africa for fresh unexploited markets and plenty of resources.
This concept is common in the natural world of living organisms. Whenever a resource is scarce or is being exploited heavily, fierce competition arises. Moving to a new location with plenty of unexploited resources becomes the logical option to consider. This happens in the natural animal world and also in the world of business and politics.
