The second assumption is that there is something exceptional about Africa, that while other continents and peoples have got or are getting richer, Africans, for reasons we can think but no longer speak in polite company, choose to remain in poverty. Our capacity to see Africa as divergent lets us off the hook so we don’t have to understand our own complicity in the challenges various African countries face today. It also means we rarely rage as we should against the actions of the corporations and governments that profit from instability, corruption or even inexperience (African negotiators at the climate talks have historically been disadvantaged by their lack of experience and the expectation among western negotiators that they should be grateful with whatever they get).
If there is, then, no innate propensity for corruption, violence or poverty in Africa, then the narratives that fuel the stereotypes need questioning. One possible explanation comes from the Nigerian author Chinua Achebe, who said: “The west seems to suffer deep anxieties about the precariousness of its civilisation and to have a need for constant reassurance by comparison with Africa.” Perhaps it’s not Africa that needs saving, but us.

Biochemical sedimentary rocks are sedimentary rocks created by the buildup of organic carbon (dead plant debris) in low-oxygen conditions (such as swamps).
When organisms utilize elements dissolved in air or water to develop their tissue, biochemical sedimentary rocks form. The calcareous skeletons of creatures such as corals, mollusks, and foraminifera are used to make most varieties of limestone.
Shells and bodies of submerged creatures are used to build biochemical sedimentary rocks. Chemical components from the water are extracted by living creatures and used to form shells and other body parts. Aragonite, a mineral related to and usually replaced by calcite, and silica are among the constituents.
