Eating is a political act.

we ask for too much salvation by legislation. All we need to do is empower individuals with the right philosophy and the right information to opt out en masse. (quoting Joel Salatin)

When chickens get to live like chickens, they'll taste like chickens, too.

Is it just a coincidence that as the portion of our income spent on food has declined, spending on health care has soared? In 1960 Americans spent 17.5 percent of their income on food and 5.2 percent of national income on health care. Since then, those numbers have flipped: Spending on food has fallen to 9.9 percent, while spending on heath care has climbed to 16 percent of national income. I have to think that by spending a little more on healthier food we could reduce the amount we have to spend on heath care.

One surprise is how deeply the food system is implicated in climate change. I don't think that has really been on people's radar until very recently. 25 to 33 percent of climate change gases can be traced to the food system. I was also surprised that those diseases that we take for granted as what will kill us - heart disease, cancer, diabetes - were virtually unknown 150 years ago, before we began eating this way.

Corn is the hero of its own story, and though we humans played a crucial supporting role in its rise to world domination, it would be wrong to suggest we have been calling the shots, or acting always in our own best interests. Indeed, there is every reason to believe that corn has succeeded in domesticating us.

There are fundamental tensions between the biological reality of the planet and the economic reality. To some extent you can adapt the economy, create a new set of rules and incentives to send it down a better track, but finally people in the first world are going to have to consume a whole lot less.
