The history of food has never had a better biographer. Required reading for anyone who eats.

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.

It takes fifteen pounds of wild fish to get you one pound of farm tuna. Not very sustainable. It doesn't taste very good either.

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

It's a fallen world. We eat and sacrifice in the process.

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.

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.
