• Our world model was built specifically to investigate five major trends of global concern – accelerating industrialization, rapid population growth, widespread malnutrition, depletion of nonrenewable resources, and a deteriorating environment. The model we have constructed is, like every model, imperfect, oversimplified, and unfinished... Our conclusions are : (1.) If the present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity...

• The value of global modelling has been severely restricted by poor appreciation of the constraints under which governments and politicians operate. Equally, the value of governments and politicians has been severely restricted by largely ignoring the very real but less immediate problems tackled by modellers.

• Mihajlo Masarovic and Eduard Pestel (1974) attempted a radical innovation by developing complex models that combined demographic projections with economic, social, environmental, and political trends, with the objective of revealing that the population predicted by the UN would necessarily lead to an an explosion of the world system during the 21st century, causing an increase in mortality and a rapid population decline.
