There were many publications arguing for limits to growth in
the late 1960s and early 1970s. One of the most famous studies
done at this time was commissioned by the Club of Rome, which
was formed in 1968 by scientists, educators, economists, humanists,
industrialists and civil servants. The study used a computer
model of the world economy to show that the existing growth
rates of population and economic activity could not continue indefinitely
on a planet that had only limited natural resources and limited
ability to deal with pollution.
In the same year, the magazine The Ecologist devoted an
entire issue (later published as the book, A Blueprint for Survival)
to arguing that economic growth could not continue into the future
without disaster. Their argument was supported by thirty-three
eminent academics.
Other significant writings included an article by economist Kenneth
Boulding and several books on population growth by Stanford Professor
of Biology, Paul Ehrlich.
