Ninety-five percent of the eggs produced in America come from factory-farmed birds. Even if free-range farms were hugely more humane, the sheer number of animals raised to satisfy people's desire for eggs, meat, and milk makes it impossible for us to raise them all on small, free-range farms.

Bulls can do nothing to demand justice. They can only defend themselves as best they can in a fight with a pre-determined ending and die never knowing why they were forced to endure such a painful and prolonged death. It's up to us, as a civilized society, to call for an end to the Running of the Bulls and bullfighting.

Even if animal tests produced a cure for AIDS, we'd be against it.
