Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
From Oui's link:
However, as discussed above, exponential human population growth and colonization of the planet may not be a sustainable development pattern. This fact calls into question a core justification for the assumption of exponential expansion of ETI civilizations. If ETI civilizations share similar development issues as human civilization, as is assumed in the Fermi Paradox, then ETI civilizations would not be able to sustain exponential expansion [20]. Likewise, if exponential expansion could not be sustained, then ETI civilizations would either have switched
6to a slower-growth development pattern or collapsed. Collectively, these possibilities suggest the "Sustainability Solution" to the Fermi Paradox: The absence of ETI observation can be explained by the possibility that exponential growth is not a sustainable development pattern for intelligent civilizations.

This line of reasoning I find in line with the arguments presented in the paper on which this diary is based. To me the similarities between the end result of the experiment in which a single paramecium is placed in a beaker of agar and allowed to multiply until the population collapses and the fate of any 'civilization undertaking exponential growth are far more compelling than are their differences. If we, as a civilization, cannot do better than to undertake exponential growth in a finite ecosystem we will richly deserve a similar fate.

The problems that arise from energy dissipation, as presented in the paper strongly argue in favor of building down our population and reducing our impact on the ecosystem if we want our species even to survive the next 500 years. IMO, absent a deliberate process to greatly reduce our impact on our environment the probabilities of anything like what we call 'civilization surviving the next millennium are dim.

Kenneth Boulding said back in the 1950s:

To believe in unlimited growth in a finite world one had to be either a fool or an economist
