While appreciating Jared Diamond's "time machine" approach in examining the challenges of resource shortages, I have serious reservations regarding his solutions.
Diamond's philosophic approach is obviously leftist which, unfortunately, leads to troubling conclusions. By including Climate Change (i.e. the religion of man-made global warming), Diamond loses all credibility in addressing humanity's responsibility regarding shortages in legitimate areas such as water and food.
What is most disheartening is Diamond's failure to recognize his own elitism, typical of other leading "catastophe" proponents such as Al Gore and Nancy Pelosi. While passionately advocating for a drastically reduced life style that can't come soon enough, we see him driving a first-rate automobile and shopping at a first-rate grocery store. Again, Diamond and other high visibility proponents would have much more credibility if they began implementing the "reduced life style" now. However, I am dubious Gore and Pelosi will be giving up their private jets and automobiles in the near future.
Like all sane people who appreciate the importance of good stewardship of our resources and the desire for responsible environmentalism, I find it most disturbing when Diamond suggests that free people cannot be trusted to address these concerns. Instead, we are to believe that only massive government regulation can offer salvation.
