- "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."

Mankind at the Turning Point (1974)
- There is a much more subtle and completely novel threat to man's survival that looms, every year more menacingly, beside that of an atomic holocaust; the cluster of world-wide problems - not only material in nature - growing at an incredible speed when viewed in historical perspective, and called by The Club of Rome the "problématique humaine. In fact, we believe that even without the atomic world war, human existence as we know it is threatened if no way can be found to resolve this crisis syndrome." (p.xi)

- There is no such concept as one limit for the entice system: rather different parts of the system face different limits at different times with the traumatic experiences for the entire system depending on the interrelationship of the constituent parts - the collapse, if it occurs, would he regional rather than global, even though the entire global system would be affected. (p.55)

- We found that technological optimism is the common and the most dangerous reaction to our findings... Technology can relieve the symptoms of the problem without affecting the underlying causes. Faith in technology as the ultimate solution to all problems can thus divert our attention from the most fundamental problem— the problem of growth in a finite system- and prevent us from taking effective action to solve it... We would deplore an unreasoned rejection of the benefits of technology as strongly as we argue here against an unreasoned acceptance of them. Perhaps the best summary of our position is the motto of the Sierra Club; not blind opposition to progress but opposition to blind progress.
Taking no action to solve these problems is equivalent of taking strong action. Every day of continued exponential growth brings the world system closer to the ultimate limits of that growth. A decision to do nothing is a decision to increase the risk of collapse.
The way to proceed is clear... [we posses] all that is necessary to create a totally new form of human society... the two missing ingredients are the realistic long-term goal... and the human will to achieve that goal. (p.88)

- [Another significant aspect of the concept of growth is the distinction that Mesarovic and Pestel draw between "undifferentiated" and "organic" growth. The former type of growth, according to these authors, consists of mere replication of cells by cellular division, usually expotentially, with an increase in quantity alone. The latter type of growth]
"involves a process of differentiation, which means that various groups of cells begin to differ in structure and function... During and after differentiation the number of cells can still increase, and the organs grow in size, but while some organs grow, others might celine."

- 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.
