$this->bbcode_second_pass_quote('Matthew Simmons', 'W')HAT THE LIMITS TO GROWTH ACTUALLY SAID
After reading The Limits to Growth, I was amazed. Nowhere in the book was there any mention about running out of anything by 2000. Instead, the book's concern was entirely focused on what the world might look like 100 years later. There was not one sentence or even a single word written about an oil shortage, or limit to any specific resource, by the year 2000.
The members of the "Club or Rome" were also not a mysterious, sinister, anonymous group of doomsayers. Rather, they were a group of 30 thoughtful, public spirited-intellects from ten different countries. The group included scientists, economists, educators, and industrialists. They met at the instigation of Dr. Aurelia Peccei, an Italian industrialist affiliated with Fiat and Olivetti.
The group all shared a common concern that mankind faced a future predicament of grave complexity, caused by a series of interrelated problems that traditional institutions and policy would not be able to cope with the issues, let alone come to grips with their full context. A core thesis of their work was that long term exponential growth was easy to overlook. Human nature leads people to innocently presume growth rates are linear.
The book then postulated that if a continuation of the exponential growth of the seventies began in the world's population, its industrial output, agricultural and natural resource consumption and the pollution produced by all of the above, would result in severe constraints on all known global resources by 2050 to 2070.
2050 isn't here yet so yea, we are still right on track for the Club of Rome to be completely correct.
