 There is disagreement about whether the first premise is true. The “readily available alternatives” condition matters: Everyone agrees that it is sometimes all things considered permissible to kill animals, e.g., if doing so is the only way to save your child’s life from a surprise attack by a grizzly bear or if doing so is the only way to prevent your pet cat from a life of unremitting agony. (Whether it is permissible to kill animals in order to cull them or to preserve biodiversity is a tricky issue that is set aside here. It—and its connection to the permissibility of hunting—is discussed in Scruton 2006b.) At any rate, animal farms are in the business of killing animals simply on the grounds that we want to eat them and are willing to pay for them even though we could, instead, eat plants.
