We need an economics fit for purpose in a finite and entropic world.

We say we need to clean up the environment; to clean up the environment, we need to be richer. But maybe getting richer is actually making us poorer.

Even if we could grow our way out of the crisis and delay the inevitable and painful reconciliation of virtual and real wealth, there is the question of whether this would be a wise thing to do. Marginal costs of additional growth in rich countries, such as global warming, biodiversity loss and roadways choked with cars, now likely exceed marginal benefits of a little extra consumption. The end result is that promoting further economic growth makes us poorer, not richer.

The laws of thermodynamics restrict all technologies, man's as well as nature's, and apply to all economic systems whether capitalist, communist, socialist, or fascist. We do not create or destroy (produce or consume) anything in a physical sense- we merely transform or rearrange. And the inevitable cost of arranging greater order in one part of the system (the human economy) is creating a more than offsetting amount of disorder elsewhere (the natural environment).

Environmental degradation is an iatrogenic disease induced by economic physicians who treat the basic malady of unlimited wants by prescribing unlimited growth.... Yet one certainly does not cure a treatment-induced disease by increasing the treatment dosage.

The economy is a wholly owned subsidiary of the environment, not the reverse.

Presumably, technology has made man increasingly independent of his environment. But, in fact, technology has merely substituted nonrenewable resources for renewables, which is more an increase than a decrease in dependence.
