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.  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.  Physical necessities that support all
physiological and industrial activity (like
food, raw materials and fuels)
 Social neccesities (like peace, stability
and education)

6. Team assumed that there would be no great changes in
human values in future and produced this graph.

7.  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.

8.  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.
