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.

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.

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.

The greenhouse is driven by three things: economy, flavor, ecology. Where ecology is what's being grown in this micro-ecology that can simultaneously thrive and better the soil/rotation, not just the flavor.

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.

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

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