Food isn't scarce in Africa if there isn't an over-abundance of negros caused by Western aid and medicine increasing their numbers dramatically. Normally, they lived where fruit trees and edible plants and roots were plentiful. They would use the resources of an area and then go somewhere new. Then the first area would get restored by nature and could be used again. The infant mortality rate was high and people died of disease or injuries a lot easier. The Westerners destroyed this balance by trying to help them.
