An Analysis of the Colonialist Roots of William Rees’s Case for Human Population Decline

Abstract

In a recent article, William Rees defends the proposition that ecological overshoot will propel human population decline in coming decades. He rightly highlights that decreasing energy availability will contribute to this demographic shift, although he understates the significance of this phenomenon. He is also correct to expect ecological overshoot to be inadequately addressed. Yet Rees’s reasoning betrays stark neglect of the colonial roots of ecological overshoot and why it goes unaddressed. This leads him to reinforce the discursive dynamics driving ecological overshoot despite avowing to criticize them. Ultimately, he makes several specious colonialist assumptions about the primary drivers of ecological overshoot. He also fails to recognize that human population decline will occur even if a suitable energy and infrastructure transition takes place. Is such a decline inevitable, as Rees claims? Yes, but this is not for the reasons he suggests. A careful analysis of his argument shows why.
