"An important new issue is emerging in the arena of sustainable development that rivals environmental concerns in importance. It is consumption — or rather, mis- and over-consumption. This is a less tractable problem than environmental degradation in that politicians see efforts to contain consumption as a superb way to lose votes. It is at the heart of the sustainability debate, as it covers the depletion of natural capital, such as key non-renewable resources, and the capacity to absorb pollution."
