''The Limits to Growth'' is a 1972 book about the computer simulation of exponential economic and population growth with finite resource supplies. Funded by the Volkswagen Foundation and commissioned by the Club of Rome it was first presented at the St. Gallen Symposium. Its authors were Donella H. Meadows, Dennis L. Meadows, Jørgen Randers, and William W. Behrens III. The book used the World3 model to simulate〔The models were run on DYNAMO, a simulation programming language.〕〔Edwards, Paul N. (2010) (''A Vast Machine: Computer Models, Climate Data, and the Politics of Global Warming'' ) MIT Press ISBN 9780262290715 pg 366-371〕 the consequence of interactions between the Earth's and human systems. The original version presented a model based on five variables: world population, industrialisation, pollution, food production and resources depletion. These variables are considered to grow exponentially, while the ability of technology to increase resources availability is only linear.〔.〕 The authors intended to explore the possibility of a sustainable feedback pattern that would be achieved by altering growth trends among the five variables under three scenarios. They noted that their projections for the values of the variables in each scenario were predictions "only in the most limited sense of the word," and were only indications of the system's behavioral tendencies.〔Peter A. Victor (2008). ''Managing Without Growth'', Edward Elgar Publishing, pp. 92-93, ISBN 978-1-84720-078-5〕 Two of the scenarios saw "overshoot and collapse" of the global system by the mid to latter part of the 21st century, while a third scenario resulted in a "stabilized world."〔Graham Turner (2008).

Commonwealth Scientific and Industrial Research Organisation (CSIRO).〕 The book continues to generate fervent debate and has been the subject of several subsequent publications. The most recent updated version was published on June 1, 2004 by Chelsea Green Publishing Company and Earthscan under the name ''Limits to Growth: The 30-Year Update''. Donella H. Meadows, Jørgen Randers, and Dennis Meadows have updated and expanded the original version.〔"To Grow or not to Grow", Newsweek, March 13, 1972, pages 102–103〕〔Donella H. Meadows, Gary.

Wallich, "More on Growth", NewsWeek, March 13, 1972, page 86.〕 ==Purpose== The purpose of ''The Limits to Growth'' was not to make specific predictions, but to explore how exponential growth interacts with finite resources. Because the size of resources is not known, only the general behavior can be explored.〔Meadows, D. (1974). The Limits to Growth, Second Edition Revised, Signet.
