An interesting article about the uprising "carbon credit" market, which would be perfect for battling the man-made CO2-related global warming problems (i.e. stuff we are responsible for).
It's a written from the point of view of the green movement, but not too strongly (IMO).
It gives an interesting look into the corruption and problems involved with this type of market.
