These factory farmers calculate how close to death they can keep the animals without killing them. That's the business model. How quickly can they be made to grow, how tightly can they be packed, how much or how little can they eat, how sick can they get without dying.

Our response to the factory farm is ultimately a test of how we respond to the powerless, to the most distant, to the voiceless - it is a test of how we act when no one is forcing us to act one way or another. Consistency is not required, but engagement with the problem is.

We perhaps know more than we care to admit, keeping it down in the dark places of our memory-disavowed. When we eat factory-farmed meat we live, literally, on tortured flesh. Increasingly, that tortured flesh is becoming our own.

Rationally, factory farming is so obviously wrong, in so many ways. In all of my reading and conversations, I've yet to find a credible defense of it. But food is not rational. Food is culture, habit, and identity.

Needless to say, jamming deformed, drugged, overstressed birds together in a filthy, waste-coated room is not very healthy. Beyond deformities, eye damage, blindness, bacterial infections of bones, slipped vertebrae, paralysis, internal bleeding, anemia, slipped tendons, twisted lower legs and necks, respiratory diseases, and weakened immune systems are frequent and long-standing problems on factory farms.

We know, at least, that this decision (ending factory farming) will help prevent deforestation, curb global warming, reduce pollution, save oil reserves, lessen the burden on rural America, decrease human rights abuses, improve publish health, and help eliminate the most systematic animal abuse in history.

The power brokers of factory farming know that their business model depends on consumers not being able to see (or hear about) what they do.

The factory farm has succeeded by divorcing people from their food, eliminating farmers, and ruling agriculture by corporate fiat.
