This paper was originally presented at the annual meeting of the program board of the Division of Overseas Ministries of the National Council of Churches. It followed a discussion by Jorgen Randers showing the implications of present world trends in growth of population and industrialization, depletion of natural resources, rise in population, and full utilization of agricultural land. Referring to the two hours of his talk and the ensuing discussion, Randers said, “The entire purpose is to convince you that exponential (...) growth cannot go on forever in a world of fixed size.” Randers stressed that overtaxing of the natural environment is caused more by industrialization than by population. Industrial processes use natural resources and emit pollution. Capital‐intensive agriculture in time decreases the productivity of land. Limiting of capital accumulation is as necessary as limiting of population. World civilization must and will move from growth to equilibrium, either by human choice or by the pressure of natural and social forces.Many trade‐offs and choices lie before us in the approaching equilibrium. We can press forward along the historical growth curves, exceed the limits of the world environment, and endure a collapse of population and industrialization back to a level the world can support. Or we can choose a redirection of law, policies, and religions to create a smooth transition to world equilibrium. Even in choosing equilibrium, alternatives arise. The higher the population, the lower will be the achieveable standard of living and quality of life. Trade‐offs will be made consciously or implicitly between advantages in the immediate future compared to advantages in the distant future. An inherent conflict exists between time horizons. Choosing to maximize the present quality of life condemns future generations to suffer for their predecessors' advantage.The reader should, if possible, read first any of those cited in notes1, 2, or 6 listed at the end of this paper before reading the following text, —J A Y W.
