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.

Whether we change our lives or do nothing, we have responded. To do nothing is to do something.

As told by Kafka's close friend Max Brod:"Suddenly he began to speak to the fish in their illuminated tanks. 'Now at least I can look at you in peace, I don't eat you anymore.' It was the time he turned strictly vegetarian.

Two friends are ordering lunch. One says, 'I'm in the mood for a burger,' and orders it. The other says, 'I'm in the mood for a burger,' but remembers that there are things more important to him than what he is in the mood for at any given moment, and orders something else. Who is the sentimentalist?

It shouldn't be the consumer's responsibility to figure out what's cruel and what's kind, what's environmentally destructive and what's sustainable. Cruel and destructive food products should be illegal. We don't need the option of buying children's toys made with lead paint, or aerosols with chlorofluorocarbons, or medicines with unlabeled side effects. And we don't need the option of buying factory-farmed animals.

It's nice to believe that when confronted with facts people will just suddenly respond to them but, in fact, most people don't really work like that.

Just how destructive does a culinary preference have to be before we decide to eat something else? If contributing to the suffering of billions of animals that live miserable lives and (quite often) die in horrific ways isn't motivating, what would be? If being the number one contributor to the most serious threat facing the planet (global warming) isn't enough, what is? And if you are tempted to put off these questions of conscience, to say not now, then when?

We can't plead ignorance, only indifference. Those alive today are the generations that came to know better. We have the burden and the opportunity of living in the moment when the critique of factory farming broke into the popular consciousness. We are the ones of whom it will be fairly asked, What did you do when you learned the truth about eating animals?

E allora quanta sofferenza è accettabile? È questa la base di tutto, ed è questo che ognuno di noi deve chiedersi. Quanta sofferenza sei disposto a tollerare per il tuo cibo?
