I was watching a program on the Amazon (river not bookshop) the other day about a group of scientists measuring the carbon absorbed by the rain forest. Why? So that Brazil can trade the carbon absobed by its trees on the internatonal carbon credit market. On the surface - sounds great - save the trees of the Amazon by selling their carbon. But, it made me think, do we ever learn? Nearly the whole of the international banking system crashed because of trade in complex fianancial instruments that nobody understood and weren’t worth the bytes used to email them around the world. Now they want us to trust the future of the environment on a financial scheme that values thin air and has all the simplicity of a Lehman’s Credit Default Swap. Hmmm… let me think about that one ؟
