in a world where only a minor portion of the land is really well suited to agriculture, man is using much of the best land with dubious efficiency.

After the journey around the world, writing Hope's Edge, I began to see that it is not possible to know what's possible - and therein lies our freedom.

With an eco-mind, we get ready for surprises, for we realize it's just not possible to know what's possible.

The problem is that our whole tribe - if you will, the larger community of humanity itself - is on a death march ecologically and in terms of the intensification of violence and conflict.

Fear doesn't have to stop us.

We got hooked on grain-fed meat just as we got hooked on gas guzzling automobiles. Big cars made sense only when oil was cheap; grain-fed meat makes sense only because the true costs of producing it are not counted.

Our food system takes abundant grain,which people can't afford,and shrinks it into meat,which better-off people will pay for.
