“Government concern with trends in population, resources, and environment is not new. Indeed, study of these issues by Federal commissions and planning boards extends back at least 70 years. The earlier studies, however, tended to view each issue without relation to the others, to limit their inquires to the borders of this nation and the short-term future, and to have relatively little effect on policy. What is new in more recent studies is a growing awareness of the interdependence of population, resources, and environment. The Global 2000 Study is the first U.S. Government effort to look at all three issues from a long-term global perspective that recognizes their interrelationships and attempts to make connections among them.
