"There have to be limits. If we project “housing starts” ninety-nine years forward at current rates, there wouldn’t be a single buildable quarter-acre lot left in the world. Not a few economists would rationalize this outcome by declaring that [in] ninety-nine years from now we will have colonies on the moon or Mars or under the . Or that technology coupled with human ingenuity will solve the problem some other way, […] by genetically reengineering human beings to be one inch tall or booting all our consciousnesses into computer servers where unlimited numbers of virtual people could dwell in unlimited virtual environments of endless cyberspace. More likely, we will remain confined to the planet Earth. Economic growth that has appeared normative and desirable during the story of industrialism is already becoming pathogenic in an economy showing more… signs of positive feedback and accelerating positive entropy manifesting as damage to the biosphere. High entropy becomes particularly problematic in an economy utterly dependent on a few… commodities […]. It becomes especially relevant when the limits to those commodities become tangible, as is now the case as we approach the global oil production peak and the actual depletion (thirty years past peak) of the North American natural gas endowment. But the collective imagination of the public cannot process the notion of a nongrowth economy, even though the limits to growth are visible all around us in everything from the paved-over suburban landscapes to the steeply rising gas prices, to played-out aquifers, to the death of the Atlantic cod fishery. We are not capable of conceiving another economic way. We are hostages to our own system."
