There Are Two, Yea, Even Three Things That I Fear

The Rational Optimist thinks that there's Room For All:

... 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...

If there are three things I fear, as a passionate environmentalist who wants to see wild habitats restored all over the world, they are biofuels, renewable electricity and organic farming. Each would demand much, much more land from nature.
