Contingent Existence, Worthwhile Lives, and Humane Animal Slaughter

Abstract

Humanely raised farm animals have lives worth living, and their existence is contingent upon human actions. Do these facts render the act of humanely slaughtering such animals permissible? I identify two ethical principles that may seem to connect these facts to the permissibility of humane animal slaughter. The first principle, inspired by the non-identity problem, exonerates some actions that maximize an individual’s well-being, but it is often inapplicable to animal slaughter. The second principle, which exonerates actions that are part of a practice that makes the animal better off, does apply to animal slaughter; but this principle is false.
