“The greatest challenge we face is a philosophical one: understanding that this civilization is already dead. The sooner we confront our situation and realize that there is nothing we can do to save ourselves, the sooner we can get down to the difficult task of adapting, with mortal humility, to our new reality. Carbon-fueled capitalism is a zombie system, voracious but sterile. This aggressive human monoculture has proven astoundingly virulent but also toxic, cannibalistic, and self-destructive. It is unsustainable, both in itself and as a response to catastrophic climate change.”
