Book excerpt: "What Mr. Wattenberg has to say about the impact of declining world population will underline its profound impact on the lives of people everywhere - from the dominance of the elderly and their demands on the resources of their governments, to the enormous potential of China and India, to the relatively privileged position of the United States vis-a-vis the major world powers. In an age already beset by a transformation in world politics, Fewer will help explain current trends as well as sketch the shape of our future."--BOOK JACKET.
