How Many People Can the Earth Support?W. W. Norton & Company, 1996 - 532 من الصفحات In this penetrating analysis of one of the most crucial questions of our time, a leading scholar in the field reviews the history of world population growth and gives a refreshingly frank appraisal of what little can be known about its future. In the process, he offers the most comprehensive account yet available of how various people have tried to estimate the planet's human carrying capacity. Few contemporary writers have addressed the issue of world population growth in such a balanced, objective way, without using it as a pretext to advance a prior political agenda. |
