World Environment Day is today, June 5. This year's WED has an economic theme: "Seven Billion Dreams. One Planet. Consume with Care". The theme of sustainable consumption sounds great, and I agree that environmental degradation does not have to be a by-product of economic growth, but I worry about the free rider problem.
Read about it here at UNEP and here at IBT (with lots of great but depressing pictures). Cool video from UNEP here.
