It is only in part the number of people. It is also what they do! People around the world are trying to emulate societies like that of the U.S., with many times their present use of resources per person. Then add many more people, and the problems seem obvious. This is the basic message of Brown et al.
But is it true? We need to look more closely - first at what is really happening to population.
