We have news of further progress in the war against stupidity that is the ecological economics movement. New Scientist tells of a new reporting group - The Economics of Ecosystems and Biodiversity- that has calculated cash values for various habitats from coral reefs to savannah. The group's first report, also covered in Le Graun, claims that the benefit-to-cost ratio of preserving natural habitats is in the range of 10:1 to 100:1. Services such as flood protection, pollution removal and the monetary benefits of tourism were taken into account to confirm what all us tree-huggers have been saying for years: that its worth more to society to protect and preserve natural landscapes than it is to sell them off to corporate developers and hedge funds. Grey party scum: take note!
