Members of the Commission on Population Growth and the American Future have formed a citizens committee to generate public support for the recommendations of the Commission that have generally been plowed under in the debate over the report's more controversial proposals.'' (Author/AL)

Authors describe genetic methods which have been used for population control in insects. Methods which are used alone or in combinations are explained briefly. (PS)

Discusses the consequences of different rates of approach to zero growth, given the history of marked differentials in fertility and mortality rates between whites and nonwhites. (DF)

Discusses a model for explaining the spread of human population explosion on North American continent since its discovery 12,000 years ago. The model may help to map the spread of Homo sapiens throughout the New World by using the extinction chronology of the Pleistocene megafauna. (Author/PS)

Presents highlights from a National Research Council report titled "Population Growth and Economic Questions: Policy Questions." Includes brief comments on the report's conclusions related to exhaustible resources, renewable resources, pollution, work productivity, economics of scale and technological innovation, schooling, income…

While increasing population pressures on the resources of the world do present real difficulties, they are not such as to be unsolvable. More and better science, technology, and growth in economic welfare are vital components in meeting these difficulties. Ideas for a new National Development Act are presented. (Author/RH)

Suggests that overproduction of offspring by early human populations would have tended to work to the selective disadvantage of the entire society. Decisions regarding population limitations have been highly personal ones based on the amount of short run effort that individuals were able and willing to invest in each child. (GS)

Discusses economic factors as the essential causes of world environment deterioration. Presents case for critical and prompt action in prevention of natural resource exhaustion and pollution, particularly by means of replacement level, population control, and consequent economic organization. (JM)

Examines increases in food production and relates these to population growth. Compares per capita food production increases in the developed versus developing nations. (GS)

Analyzes the recent trends in food supply and demand around the world. Present predictions are pessimistic and indicate that poor harvests will result in world-wide food shortages. Factors affecting the food requirements of under-developed countries, such as population growth, crop yields and weather patterns, are examined. (JR)

Author suggests that study of population growth is not a field of study only for ecologists. Population growth is related with social sciences in the nature of its process and future consequences. Broader, comprehensive approaches to this problem will be useful. (PS)
