Dr. William Rees on ‘The Dangerous Disconnect Between Economics and Ecology’

From The Institute for New Economic Thinking:

The world economy is depleting the earth’s natural resources, and economists cling to models that make no reference whatsoever to the biophysical basis that underpins the economy. That’s why ecological economics is needed, says William Rees in this INET interview.

Standard economics portrays the economy as a circular flow: households pay money to firms in exchange for goods and services, and firms pay wages to households in exchange for labor. Textbooks describe this circular flow as self-perpetuating, capable of infinite expansion. William Rees argues that the textbooks get it wrong; he says the production of our goods and services depends on the extraction of material from ecosystems, causing resource depletion on the one hand, and excess pollution on the other.

William Rees, best known in ecological economics as the originator and co-developer of ‘ecological footprint analysis’, says the United States is using four or five times its fair share of the world’s total bio-capacity. In order to bring just the present world population up to the material standards enjoyed by North Americans, we would need the biophysical equivalent of about three additional planet earths.
