Whether economic growth can be sustained in a finite natural world is one of the earliest and most enduring questions in economic literature. Even with unprecedented growth in human population and resource consumption, humans have been quite adept at finding solutions to the problem of scarce natural resources, particularly in response to signals of increased scarcity. Because environmental resources generally are not generally traded on markets, however, scarcity signals for these resources may be inadequate, and appropriate policy responses are difficult to implement and manage. In the debate over the economic scarcity of natural resources, one significant change in recent years has been a greater focus on the ecosystem services and the resource amenities yielded by natural environments. The general conclusion of this paper is that technological progress has ameliorated the scarcity of natural resource commodities; but resource amenities have become more scarce, and it is unlikely that technology alone can remedy that.
