"Since growth is an absurd short-lived anomaly, what about leveling out in population, resource use per capita, and adopting a steady-state economy? The problem here is that the rate at which we are depleting one-time resources today is unsustainable. We’re simply spending our bank account without paying attention to the balance and without any source of additional income. Most clearly, forests and wild spaces are down by a factor of two in the last 60 years and will be gone within 60 years at current rates of depletion. Before even getting to steady-state conditions, inevitable near-term increases in population together with sought-after increases in standards of living around the world spell an even shorter lifetime for critical habitats. Meanwhile, fisheries are failing in domino fashion; aquifers are being depleted at rates alarmingly higher than replacement; soils are degrading and arable land is lost; fertilizer depends on a finite resource; habitat loss is resulting in species extinctions far in excess of natural rates. Even the plunder of mineral resources in the seemingly infinite crust is getting harder, only a fleeting century or so into our spree. Sustaining present levels for even a few more centuries is a dubious (i.e., unsubstantiated) proposition. It is practically absurd to imagine sustaining present practices for 10,000 years. Humans simply have not yet demonstrated an ability to maintain a technological society without utter reliance on grossly unsustainable inheritance spending."
