The failure to achieve sustainability may be in our genes

ABSTRACT Belief in human exceptionalism—the idea that humans are not bound by the same evolutionary constraints and biophysical limitations as other organisms—is rampant in society. To ignore human nature in favor of such a constructivist perspective is foolhardy because it compromises prospects for achieving sustainability. Human activity already exceeds Earth's long-term carrying-capacity, yet many governments and ordinary citizens alike are focused on fostering a new round of material growth. Few academics pay more than lip service to the causal drivers behind such unsustainable behavior. In particular, the sociological model for dealing with overshoot focuses on the shortcomings of social institutions, effectively decoupling the problem from H.sapiens' innate expansionist tendencies and such instinctive drives as competition for social status, mates, territory, and other resources. Understanding human unsustainability depends as much on insights from the behavioral and biological sciences as from the social sciences. Merging bioevolutionary, psychological, and sociological explanations into a unified framework is an essential step in moderating human (over)consumption. Humanity is now dangerously close to global collapse; as academics we have the obligation to investigate humanity's unsustainability conundrum through an interdisciplinary lens and apply our new understanding to solving global and local problems before solutions become moot.
