The global lily pond in which four billion of us live may already be half full. Although UN projections show world population continuing to grow until it reaches ten to sixteen billion, Lester Brown believes this is unrealistic. In this fascinating analysis of the four principal biological systems on which humanity depends-fisheries, forests, grasslands, and croplands-the author shows that the demands at current levels of population and per capita consumption often exceed the long-term carrying capacity. He documents the overfishing, deforestation, and overgrazing that are gradually undermining human life support systems. He also explains that with energy shortages anticipated in the early eighties and a projected downturn in world oil production in the early nineties, the world must quickly shift to renewable energy resources.
These accommodations constitute an enormous challenge. They suggest a broad and profound change, one that will affect virtually every facet of human existence. The coming transformation will surely give rise to new social structures and to an economic system materially different from any we know today. Like other periods of convulsive change, it will put great stress on both individuals and institutions.
