The Palm Oil Sector?

Palm oil 5And he told them about this new God, the Creator of all the world and all the men and women. He told them that they worshipped false gods, gods of wood and stone. A deep murmur went through the crowd when he said this. He told them that the true God lived on high and that all men when they died went before Him for judgment. Evil men and all the heathen who in their blindness bowed to wood and stone were thrown into a fire that burned like palm-oil. –Chinua Achebe (1958)

There’s something fishy about the bushmeat narrative of Ebola.

In August we explored the way the story internalizes the outbreak to local West Africans. It’s part of the ooga booga epidemiology that detracts from the circuits of capital, originating in New York, London and elsewhere, that fund the development and deforestation driving the emergence of new diseases in the global South.

But in addition, and not unconnected, there’s something missing from the model’s purported etiology. Indeed, Ebola may have almost nothing, or only something tangentially, to do with the bushmeat trade.

King Leopold’s Pandemic

The origins of HIV offer a great example of the ways treating human impact as an afterthought—discussed in our previous post—locks the study of pathogens into limited and oftentimes downright drunken trajectories.

In 2006 Beatrice Hahn and her colleagues identified the likely source for the SIVcpz progenitor that seeded HIV-1 group M, the clade that produced the AIDS pandemic. The team identified two wild chimpanzee groups in the southeastern corner of Cameroon—50 km north of Ouesso—with SIVcpz phylogenetically closest to group M.

The team hypothesized the virus spread to humans there a hundred years or so ago before making its way south by the Sangha and Congo Rivers to Leopoldville (now Kinshasa), one of several new colonial administrative centers in the area. By a relaxed molecular clock permitting different rates of nucleotide substitution across phylogenetic branches, Worobey et al. (2008) dated the emergence of group M to 1908 (1884-1924). After circulating regionally for decades, diversifying into many of its present-day subtypes, the virus exploded in population size and made its way out onto the global travel network and to the rest of the world.
