I finished all of them including chapter 20. Lot of good information to ponder, however he is still using data the way he wants to support his theory. He certainly raises some good points. Doesn't offer any solutions or actions for you to take, even though he says he will. My guess is he publishes a news letter or something to get money other then the donation he requests at the end. If he is right, everyone's way of life will be distroyed as we know it today.
