『Abstract
　The status of the controversy concerning remaining supplies of mineral resources is examined. It is concluded that a serious shortage of a number of vital raw materials will become evident during the next few decades. Calculations are made to show that reserve and consumption data can vary within wide margins without significantly affecting this conclusion. The reasons for the impending crisis are examined and suggested solutions assessed.』
