“Either by the year 2050 we’ve succeeded in developing a sustainable economy, in which case we can then ask your question about 100 years from now, because there will be 100 years from now; or by 2050 we’ve failed to develop a sustainable economy, which means that there will no longer be first world living conditions, and there either won’t be humans 100 years from now, or those humans 100 years from now will have lifestyles similar of those of Cro-Magnons 40,000 years ago, because we’ve already stripped away the surface copper and the surface iron. If we knock ourselves out of the first world, we’re not going to be able to rebuild a first world.”

Say it with me: I WILL NOT GO BACK INTO THE CAVE.

Sustainability is zero sum bullshit. Hair shirt greens can eat my shorts. Either we build up and out, or we fall back and let the next species takeover in a million years.

May an asteroid wipe out any closed mind, human purist, Puritan Earth, false progress civilization. They won’t see it coming anyway. Ahem.
