people die each year due, directly or indirectly, to malnutrition. Even more serious is the consequence of major crop failures which are likely to occur from time to time. "The most serious consequence for the short and middle term is the possibility of massive famines in certain parts of the world, especially the poorest regions. World needs for food rise by 2.5 percent or more per year (making a modest allowance for improved diets and nutrition) at a time when readily available fertilizer and well-watered land is already largely being utilized. Therefore, additions to food production must come mainly from higher yields. "Countries with large population growth cannot afford constantly growing imports, but for them to raise food output steadily by 2 to 4 percent over the next generation or two is a formidable challenge." Key insights "The U.S. economy will require large and increasing amounts of minerals from abroad, especially from less developed countries [see National Commission on Materials Policy, Towards a National Materials Policy: Basic Data and Issues, April 1972]. That fact gives the U.S. enhanced interest in the political, economic, and social stability of the supplying countries. Wherever a lessening of population pressures through reduced birth rates can increase the prospects for such stability, population policy becomes relevant to resource supplies and to the economic interests of the United States.... The location of known reserves of higher grade ores of most minerals favors increasing dependence of all industrialized regions on imports from less developed countries. The real problems of mineral supplies lie, not in basic physical sufficiency, but in the politico-economic issues of access, terms for exploration and exploitation, and division of the benefits among producers, consumers, and host country governments" [Chapter III, "Minerals and Fuel"]. "Whether through government action, labor conflicts, sabotage, or civil disturbance, the smooth flow of needed materials will be jeopardized. Although population pressure is obviously not the only factor involved, these types of frustrations are much less likely under conditions of slow or zero population growth" [Chapter III, "Minerals and Fuel"]. "Populations with a high proportion of growth. The young people, who are in much higher proportions in many LDCs, are likely to be more volatile, unstable, prone to extremes, alienation and violence than an older population. These young people can more readily be persuaded to attack the legal institutions of the government or real property of the 'establishment,' 'imperialists,' multinational corporations,
