The Limits to Growth (LTG) is a 1972 report [2] that discussed the possibility of exponential economic and population growth with finite supply of resources, studied by computer simulation. [3] The study used the World3 computer model to simulate the consequence of interactions between the Earth and human systems.
In their 1972 publication Limits to Growth, their recommendations were focused on "how to slow growth". In the 2004 Limits to Growth: The 30-Year Update, the message has changed. Meadows explained: "Now we must tell people how to manage an orderly reduction of their activities back down below the limits of the earth's resources." [9]
The World3 model is a system dynamics model for computer simulation of interactions between population, industrial growth, food production and limits in the ecosystems of the earth. It was originally produced and used by a Club of Rome study that produced the model and the book The Limits to Growth (1972).
Thinking in Systems provides an introduction to systems thinking by Donella Meadows, the main author of the 1972 report The Limits to Growth, [1] and describes some of the ideas behind the analysis used in that report.
The Club of Rome stimulated considerable public attention with the first report to the club, The Limits to Growth. [7] Published in 1972, its computer simulations suggested that growth of production and consumption could not continue indefinitely because of either resource depletion or unmanageable levels of pollution.
In 1972, Meadows was on the MIT team that produced the global computer model "World3" for the Club of Rome, providing the basis for The Limits to Growth. The book reported a study of long-term global trends in population, economics, and the environment.
Aurelio Peccei (Italian pronunciation: [auˈrɛːljo petˈtʃɛi]; 4 July 1908 – 14 March 1984), was an Italian industrialist and philanthropist, who co-founded with Alexander King and first president of the Club of Rome, an organisation which, in 1972, produced The Limits to Growth report.
The Planetary Boundaries framework acknowledges the influence of the 1972 study, The Limits to Growth, that presented a model in which exponential growth in world population, industrialization, pollution, food production, and resources depletion outstrip the ability of technology to increase resources availability.
