Two really interesting books on global population growth were recently published, one by Stephen Emmott (1) and one by Alan Weisman (2). After seeing reviews on line I look forward to reading both of these books. It is about time that someone clearly stated that we need not merely to stabilize global population but to dramatically reduce it in order to prevent total environmental disaster. Unfortunately the trends are not encouraging. The UN has just revised some of its global population predictions upward. Moreover the much-hallowed ‘demographic transition’ whereby increased wealth leads to lower fertility is showing some strain. Thus some very recent data indicates that in China and elsewhere, higher income women are having more rather than fewer offspring. It is hard to see how voluntary measures to spread use of contraception will really impact the enormous momentum of current population trends. The projections for population growth in certain less developed areas such as Africa are truly frightening and will be accompanied by increased consumption, resource depletion and environmental degradation. However, the really sad thing is that the US, which should know better, continues to pursue economic policies that emphasize rapid growth, based partly on an immigration-driven rapid population increase. We need to start thinking about new economic models that do not require constant growth (and constantly increasing environmental destruction) in order to attain a decent life-style for most people. A few economists have started to address this task (3).
