“Although the reserves of natural resources in a nation are often discussed in terms of physical quantities, economic concepts of cost, prices, and present values must be considered if practical conclusions are to be reached. In addition to needless alarms about natural resources running out, there have also been, conversely, unjustifiably optimistic statements that some poor country has so many billions of dollars’ worth of “natural wealth” in the form of iron ore or bauxite deposits or some other natural resource. Such statements mean very little without considering how much it would cost to extract and process those resources—and this varies greatly from place to place.”
