I'm not an environmentalist, or a doctor, or a nutritionist.

I said, 'Don, what's sustainable about feeding chicken to fish?'

In food, issues that surround purchasing and that whole realm have a very political component and they branch into stories that can be really compelling. Just being on the farm, interacting with all these people in the industry, leads to personal narratives that can be used to make a larger point.

Vegetables deplete soil. They're extractive. If soil has a bank account, vegetables make the largest withdrawals.

I think all chefs who pursue great flavor have good ethics.

If you just think exclusively about what would be the best tasting or the most profitable, you're just not seeing the big picture.

If you look at the carrying capacity of agricultural areas throughout the world, their ecological habitats are changing. So I think we're looking at - in our lifetime - great collapses of food services.
