This report focuses on the interdependency of land, food, and population in the U.S. economy. The United States is in a privileged situation compared to other nations in the world: the per capita endowment of natural resources is relatively high because of the relatively low population density. At the same time, the United States is seriously risking losing this privilege if more attention is not given to the control of population growth (including immigration), the sustainable management of natural resources, and the development of alternative energy sources. The aim of this report is to increase the awareness of policy makers and the public of the importance of the interaction between population growth, self-sufficiency in food production, standard of living and, ultimately, national security.
