Food and basic commodities have been getting cheaper at the same time our population has expanded, so why should we worry about resource scarcities?
In order to produce the greater and greater quantities of food needed to satisfy an expanding population, our lands have been deforested and overgrazed and our soil eroded. And don t forget the quality of life issues associated with population growth: more pollution, more sprawl, tighter housing markets, overcrowded schools, traffic congestion, and vanishing open spaces.
