Perhaps the most important issue that African nations face is pervasive poverty. A very significant proportion of the world's poorest people live in Africa. African nations have attempted to deal with the issue by exploiting the continent's considerable natural resources and inviting foreign investment, among other solutions. The effectiveness of these solutions has been compromised by instability in government, corruption, civil war, and other problems in many African nations. All of these problems, to varying degrees, are legacies of colonial exploitation, which may, in the final analysis, be understood as the fundamental underlying issue faced by Africans.
