Forty years after publication of "The Limits to Growth"
Forty years ago, a team of researchers published The Limits to Growth, a study based on computer modeling. Its conclusions based on a "standard run" indicated a collapse of the global economic system around the middle of this century. 10 years ago, a study found a strong concurrence of the predictions with the reality of the time, and a similar study done recently shows similar results.
