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

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

Conventional agriculture has never succeeded in feeding the world, and it's never produced anything good to eat. For the future, we need to look toward alternatives.

When you pursue great flavor, you also pursue great ecology.

For the past 50 years, we've been fishing the seas like we clear-cut forests. It's hard to overstate the destruction. Ninety percent of large fish, the ones we love - the tunas, the halibuts, the salmons, swordfish - they've collapsed.

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.

In the rush to industrialize farming, we've lost the understanding, implicit since the beginning of agriculture, that food is a process, a web of relationships, not an individual ingredient or commodity.
