Abstract
The critical problems that scientists warned about decades ago are now upon us. There is a near universal consensus that global warming is human-caused and that its effects are now accelerating. Biodiversity loss and ecosystem disruption is now well-documented. The global connections between social disruption, resource use and environmental degradation are now all too familiar. This information is all the more disturbing in view of the well-documented collapse of scores of past civilizations whose cultural patterns of behaviour have been described as 'self-organized' extinction. Policies to deal with the issues of sustainability have been hampered by a one-dimensional economic theory that has until recently dominated pubic discourse. Using the concept of 'generalized Darwinism', this paper focuses on the contributions a revitalized science of economics can bring to the sustainability debate. It ends with a cautiously pessimistic assessment of the prospects for sustainability.
