“In 1972, the Club of Rome published Limits to Growth, a study based on MIT computer models that simulated the relations between the earth’s resources and the human population. As a forecasting tool, the study argued that the continued consumption of resources at the current rate was unsustainable. Its call for new sustainable environmental and social policies was continued in subsequent studies—the Bruntland Commission’s Our Common Future and Agenda 21: The Earth Summit Strategy to Save Our Planet. Both originated within the United Nations system, the latter in conjunction with the Rio Earth Summit in 1992.” – Victor Margolin, “Design, the Future and the Human Spirit“
