Abstract

The concentration of metals into ore bodies amenable to exploitation results from the integration of geological processes occurring over billions of years. The heritage of wealth represents a nonrenewable resource which is eventually depleted, usually in periods of less than a few hundred years. Examples from the industrialized nations show a typical cycle of production rising to a peak and eventually dropping to zero. On a world scale, a comparable history is predicted, and estimates indicate that few metals have total reserves that can extend beyond 200 years. The limit in metal resources poses a threat to the consumer-oriented societies now dominant and increasing in the world. Technical advice can predict the shortages and adequately pose short term solutions. However, viewed from a longer time base, the only solution to eventual metal shortages is through a major restructuring of the socio-economic base of consumer-oriented societies.
