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.

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

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.

The greatest lesson came with the realization that good food cannot be reduced to single ingredients. It requires a web of relationships to support it.

I'm not here to say I don't eat vegetables - I do, a lot of them - but, from a soil perspective, they're actually more costly than a cow grazing on grass.

We're achieving better marbling and better flavor with old world wisdom that's been passed down for generations but we're still using technology.

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.
