Ok the message seems to have gotten through to most of us that we not only need to change the way we live to reduce global warming but also must do our bit to improve the environment. How else to contribute one's quota to a healthier environment than carbon offsetting. Of course in principle it is a good laudable idea. In reality most do not grasp the complexity of the scheme while others do not set much stock by its integrity.
I find this piece in The Guardian about the issue most apt and interesting.
