This volume contains the proceedings of a symposium dealing with the problems of feeding the growing world population. It is in four sections: Population and resources; the Cost: natural and economic constraints; the Alternatives; and the Cost: health.An overall view of world food supply and population is presented from FAO data by R. D. NARAIN (p. 3). The " protein fallacy " enters the debate early on, as G. BORGSTROM (p. 43) states that we need to struggle for increased food supplies in the developing countries, while P. V. SUKHATME (p. 53) uses Indian data to demonstrate that in the sub-continent there is a shortage of food energy in diets rather than of protein alone. Sukhatme also points out the necessity of evaluating diets in a socioeconomic context. S. J. HOLT (p. 77) reviews the possibilities of increasing world fish catches and J. T. WILLIAMS stresses the need to preserve the genetic diversity of wild food plants so that we may have a rich genetic " pool" to dip into when we need to strengthen the existing cultivated stocks. G. LEACH (p. 139) calculates energy costs for the production of a variety of foods and demonstrates how often the cost of producing and preparing a food greatly exceeds the energy value of the food itself. Thus efficiency (in terms of output per acre) is bought at the cost of very high energy inputs, which could not be duplicated by many developing countries. J. T. WORGAN (p. 179) also takes up the theme of how to provide more food without unnecessarily wasteful inputs.
