Herman Daly is probably the most prominent advocate of the need for a change in economic thinking in response to environmental crisis. An iconoclast economist who has worked as a renegade insider at the World Bank in recent years, Daly has argued for overturning some basic economic assumptions. He has a wide and growing reputation among environmentalists, both inside and outside the academy. Daly argues that if sustainable development means anything at this historical moment, it demands that we conceive of the economy as part of the ecosystem and, as a result, give up on the ideal of economic growth. We need a global understanding of developing welfare that does not entail expansion. These simple ideas turn out to be fundamentally radical concepts, and basic ideas about economic theory, poverty, trade, and population have to be discarded or rethought, as Daly shows in careful, accessible detail. These are questions with enormous practical consequences. Daly argues that there is a real fight to control the meaning of "sustainable development", and that conventional economists and development thinkers are trying to water down its meaning to further their own ends. Beyond Growth is an argument that will turn the debate around.
