The left has allways agreed with the capitalists. They both want to exploit the planet. To merely question that is radical. You are right Barry. The doctrine of continuous and unlimited economic growth is the doctrine of death.

There is no extraordinary effort to abate pollution or conserve resources. The simulated world tries to bring all people through the demographic transition and into an industrial and then post-industrial economy. The global population in Scenario 1 rises from 1.6 billion in the simulated year 1900 to over 5 billion in the simulated year 1990 and over 6 billion in the year 2000. Total industrial output expands by a factor of 20 between 1900 and 1990. Pollution in that simulated year has just begun to rise noticeably.
