Bill, exactly. Human beings are right up there with rats and cockroaches in our ability to adapt to different environments, a classic generalist species well adapted to sudden change and disruption. Given the geographic spread and the diversity of environments currently inhabited by Homo sap., too, we're an exterminator's nightmare. I expect global population to bottom out in two centuries or so at well under half a billion people, but that's an ample breeding population for long term survival, to say nothing of the impact of all that Darwinian selection. - John Michael Greer
