For every ten tuna, sharks, and other large predatory fish that were in our oceans fifty to a hundred years ago, only one is left.

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?

Every turkey sold in every store and served in every restaurant was the product of artificial insemination. If it were only for efficiency, that would be one thing, but these animals literally can’t reproduce naturally. Tell me what could be sustainable about that?

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.

The point of eating these special foods with those special people at those special times was that we were being deliberate, separating those meals out from the others. Adding another layer of deliberateness has been enriching. I'm all for compromising tradition for a good cause, but perhaps in these situations, tradition wasn't compromised so much as fulfilled.

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?
