“The Population Puzzle” examines the psychological, physiological, and sociological effects of overcrowding on man and animals, as author A. H. Drummond, Jr. skillfully draws together the clues scientists have gathered from animals – both in controlled environments and in their natural habitat - that may relate to human behavior.  He describes also the early experiments now being carried out with human groups.  In a simple manner Mr. Drummond sums up a vitally important concern – how may people be affected, how will they react to severe overcrowding?
