I predict that by the second half of this century nine billion human beings will be living mostly prosperous lives, eating chickens and pigs and cattle while coexisting with about as much nature as was there before we even came on the scene. We will be steadily decreasing the footprint of each human life by moving to cities, getting our food from intensive fields fertilized with nitrogen fixed from the air, our energy from natural gas or nuclear reactors, rather than horse hay or dammed rivers, and our buildings from steel and glass from beneath the ground, rather than forest timber.
