If you were to ask me what the crisis in the present is, as an evolutionary biologist I have to go back millions of years and try to connect all the dots, going back to man as a single‐celled organism to present time, and saying what is it that is causing modern consternation? More importantly, is there a pattern? Has this happened before? Were there some ordinary people like you and I, shopkeepers in Rome, who were standing around and saying, “You know, our leaders don’t seem to be on top of our problems. They seem to be getting worse one generation after another.”
Benevolence isn’t inefficient and I’m a big fan of benevolence. It’s just that it’s not enough. It’s okay for a group of twenty‐five or fifty people where everyone knows everyone. But when you have 300 million in the US or 7 billion in the world, if we were self‐sufficient and we had to produce everything for ourselves we’d all die, or 99% of us would die. So we have to cooperate with each other. But the only way to cooperate with each other in such large numbers is through markets.
The best justification we have for killing fifty‐six, fifty‐seven, whatever billion land animals and a trillion sea animals every year is that they taste good. And so, in a sense how is this any different from Michael Vick, who likes to sit around a pit watching dogs fight, or at least he used to?
