3.7 Limits to growth

  1. 1. Döndü KılınçIDF Bilkent High School IB ESS
  2. 2.  Studied by the Club of Rome (1970) › Population › Agricultural production › Industrial production › Natural resources › Pollution These factors grow at exponential rate  Revision for exponential rate
  3. 3.  Lilies on a pond -example The apparent suddenness with which the exponential growth of a phenomenon approaches to a fixed limit. If the predicted growth of world population is correct then there is an alarmingly short space of time for preventive action.
  4. 4.  Physical necessities that support all physiological and industrial activity (like food, raw materials and fuels) Social neccesities (like peace, stability and education)
  5. 5. Team assumed that there would be no great changes in human values in future and produced this graph.
  6. 6.  If present trends continue, the limits to growth will be reached in the next 100 years – the result will probably be a sudden and uncontrollable decline in population and industrial capabilities. It is possible to alter these growth trends and to establish a condition of ecological and economic stability that is sustainable into the future.
  7. 7.  It’s a world model: not distinguish between different parts of the world. Ignores spatial distribution of population, resources, agriculture, industry and pollution. People and resources do not always coincide with space. Their distribution and size are part of the world’s problem. The model emphasizes exponential growth and not the rate of discovery of new resources or of new users of resources.
