The great virtue of a diversified food economy, like a diverse pasture or farm, is its ability to withstand any shock. The important thing is that there be multiple food chains, so that when any one of them fails-when the oil runs out, when mad cow or other food-borne diseases become epidemic, when the pesticides no longer work, when drought strikes and plagues come and soils blow away-we'll still have a way to feed ourselves.

All money for agricultural extension, land grant universities has been toward developing industrial food. Lots of money has been invested toward maximizing yield. If you took even a small amount of that money and put it toward organic research, I don't have any doubts you could match those yields.

That anyone should need to write a book advising people to "eat food" could be taken as a measure of our alienation and confusion. Or we can choose to see it in a more positive light and count ourselves fortunate indeed that there is once again real food for us to eat.

The first step towards solving the omnivore's dilemma is knowledge: eating with full consciousness. When that happens, I have a lot of confidence that people will make good choices.

I try very hard to tell stories and not lecture. I try to approach things as an amateur and not an expert, so that when I'm doing something, I'm starting out in a place a lot like where my readers start out - which is to say, naïve.

Another day it occurred to me that time as we know it doesn't exist in a lawn, since grass never dies or is allowed to flower and set seed. Lawns are nature purged of sex or death. No wonder Americans like them so much.

Now that I know how supermarket meat is made, I regard eating it as a somewhat risky proposition. I know how those animals live and what's on their hides when they go to slaughter, so I don't buy industrial meat.
