According to John Kozy
The Age of Enlightenment was born sometime around the beginning of the eighteenth century. A mere three-quarters of a century later, industrialization ushered in the Age of Endarkenment, and human life has grown more and more perilous ever since.
When the economic advantages of industrialization have dissipated, humanity will still be stuck in a world filled with bioundegradable junk, hazardous sites, raped environments, the unending consequences of the often accidental importation of alien species, polluted air and water, and numerous other consequences, the costs of which economists have never taken into consideration.
A degraded sewer world. Hey kids, someday all this will be yours!
