Beyond the Limits by Donella Meadows, Dennis Meadows and Jorgen Randers Books on: Beyond the Limits by Donella Meadows, Dennis Meadows and Jorgen Randers 300 pages, paperback, Chelsea Green, 1992 The authors of Beyond the Limits apply computer modeling techniques to population and economic growth scenarios. They conclude that the global industrial system has already overshot some of the earth's vital ecological limits and could collapse by the middle of the next century-unless we quickly commit ourselves to sweeping systematic changes. Praise for Beyond the Limits 'When a model has reached the formal perfection of World3, and when so much effort and talent have gone into presenting its methodology in intelligible detail, its conclusions cannot be dismissed without resorting to similar methods and raising new questions to be answered by new models.' -Etienne van de Walle, Science Quotes from Beyond the Limits 'The earth is finite. Growth of anything physical, including the human population and its cars and buildings and smokestacks, cannot continue forever. But the important limits to growth are not limits to population, cars, building, or smokestacks, at least not directly.

They are limits to throughoutput-to the flows of energy and materials needed to keep people, cars, buildings, and smokestacks functioning. The human population and economy depend upon constant flows of air, water, food, raw materials, and fossil fuels from the earth. They constantly emit wastes and pollution back to the earth. The limits to growth are limits to the ability of the planetary sources to provide those streams of materials and energy, and limits to the ability of the planetary sinks to absorb the pollution and waste. 'On a local scale, overshoot and collapse can be seen in the processes of desertification, mineral or groundwater depletion, poisoning of soils or forests by long-lived toxic wastes. Legions of failed civilizations, abandoned farms, busted boomtowns, and abandoned, toxic industrial lands testify to the 'reality' of this system behavior. On a global scale, overshoot and collapse could mean the breakdown of the great supporting cycles of nature that regulate climate, purify air and water, regenerate biomass, preserve biodiversity, and turn wastes into nutrients.
Twenty years ago few people would have thought ecological collapse on that scale possible. Now it is the topic of scientific meetings and international negotiations.' 'The human world can respond in three ways to signals that resource use and pollution emissions have grown beyond their sustainable limits.
