Years back I criticized Jared Diamond’s “Collapse”, specifically on the subjects of Greenland and Easter Island, and gave an update when new evidence on Greenland supported my critique. I had less criticism for his take on Haiti (or the other places discussed in the final section of the book). The more recent the history, the less we have to rely on Diamond’s often implausible speculation. But now it appears that by relying on the conventional wisdom, Diamond also exaggerated the environmental plight of Haiti. Hat-tip to Marginal Revolution.
