Humanely raised farm animals have lives worth living, and they would not exist if consumers did not purchase humane animal products. In this paper, I acknowledge that, because of these facts, it may be that such purchases do not wrong the animals who are thereby caused to exist. But I argue that these purchases are nevertheless wrong because they wrong farmers. Even if a consumer's purchase of humane animal products is exonerated by the animals’ worthwhile and contingent lives, a farmer's act of slaughter is not. I argue further that committing moral wrongs, such as animal slaughter, makes one worse-off. The consumer's purchase causes the farmer to be worse-off in this way. Thus, purchasing humane animal products is wrong because it wrongs the farmer.
