When the authors get close to something I am very familiar with, like the recycling rates, the presented "facts" fall apart. This causes me to question the book. Also, the authors must be very embarassed by the current price of gasoline in the states, having asserted that we are immune to energy shocks. It is too easy, and often not very helpful, to say what we don't know and to call things into question. This paralyzing approach will not save endangered species, or improve our environment.
