"By turning the natural world into a subsidiary of the corporate economy, it reasserts the biblical doctrine of dominion. It slices the biosphere into component commodities: already the government’s task force is talking of "unbundling" ecosystem services, a term borrowed from previous privatisations. This might make financial sense; it makes no ecological sense. The more we learn about the natural world, the more we discover that its functions cannot be safely disaggregated."
Good article in the Guardian by George Monbiot on the monetisation of nature.
In the Responses to Climate Change blog, ecological economist Robert Costanza et al reply to Monbiot’s arguments.
