There's a schizoid quality to our relationship with animals, in which sentiment and brutality exist side by side. Half the dogs in America will receive Christmas presents this year, yet few of us pause to consider the miserable life of the pig - an animal easily as intelligent as a dog - that becomes the Christmas ham.

I realize that at a certain point if we're going to change our food system, it's going to be the next generation that's going to be critical. This generation is very interested in food issues, very concerned about things like animal welfare and the impact of the food system on the environment.

When you're cooking with food as alive as this -- these gorgeous and semigorgeous fruits and leaves and flesh -- you're in no danger of mistaking it for a commodity, or a fuel, or a collection of chemical nutrients. No, in the eye of the cook or the gardener ... this food reveals itself for what it is: no mere thing but a web of relationships among a great many living beings, some of them human, some not, but each of them dependent on each other, and all of them ultimately rooted in soil and nourished by sunlight.

If you can't pronounce it, you shouldn't be eating it.

This for many people is what is most offensive about hunting—to some, disgusting: that it encourages, or allows, us not only to kill but to take a certain pleasure in killing. It's not as though the rest of us don't countenance the killing of tens of millions of animals every year. Yet for some reason we feel more comfortable with the mechanical killing practiced, out of view and without emotion by industrial agriculture.

There are many people who don't do well on a vegetarian or vegan diet, that for them, meat is a very nutritious food. So, I'm not prepared to give up meat. I don't think we need to give up meat, but we certainly need to change the way we raise meat and diminish the amount of it in our diet.

If you're a politician it's very useful to say that we can have economic growth and at the same time green the economy, but writers just have to face up to the fact that there are some fundamental tensions between the economic order and the biological order.
