One popular defence of moral omnivorism appeals to facts about the indirectness of the diner’s causal relationship to the suffering of farmed animals. Another appeals to the claim that farmed animals would not exist but for our farming practices. The import of these claims, I argue, has been misunderstood, and the standard arguments grounded in them fail. In this paper, I develop a better argument in defence of eating meat which combines resources from both of these strategies, together with principles (...) of population ethics, and discuss its implications for which sorts of meat it is permissible to eat. According to the diner’s defence, there is an asymmetry between producers and consumers of meat. Producers can prevent the suffering of animals without preventing their existence, but consumers cannot. This asymmetry grounds a defence against harm-based objections to eating meat which is available to the consumer alone, and which avoids the controversial commitments about moral status or the interests of nonhuman animals endemic to existing attempts to justify omnivorism.

Most people agree that inflicting unnecessary suffering upon animals is wrong. Many fewer people, including among ethicists, agree that painlessly killing animals is necessarily wrong. The most commonly cited reason is that death (without pain, fear, distress) is not bad for them in a way that matters morally, or not as significantly as it does for persons, who are self-conscious, make long-term plans and have preferences about their own future. Animals, at least those that are not persons, lack a morally (...) significant interest in continuing to live. At the same time, some argue that existence itself can be good, insofar as one’s life is worth living. For animals, a good life can offset a quick, if early, death. So, it seems to follow that breeding happy animals that will be (prematurely) killed can be a good thing overall. Insofar as slaughter and sale makes it economically sustainable to raise new ones, who would otherwise not exist, raising and killing animals for food who will have lives worth living is good overall. It benefits them as well as consumers, and makes the world better by adding to the sum of happiness. The process of raising and killing animals with positive welfare produces a sequence of replacement that maintains or increases overall welfare, all else being equal (assuming in particular no overall negative impact on the welfare of other parties). Call this the Replaceability Argument (RA) and the ensuing controversy the Replaceability Problem (RP). This is a problem at the crossroads of the ethics of killing, agricultural ethics, procreation ethics, and population ethics. (shrink)

Few moral arguments have been made against vegetarian diets. One exception is the “Logic of the Larder:” We do animals a favor by purchasing their meat, eggs, and milk, for if we did not purchase these products, fewer animals would exist. This argument fails because many farm animals have lives that are probably not worth living, while others prevent a significant number of wild animals from existing. Even if this were not so, the purchase of animal products uses resources that (...) could otherwise be used to bring a much greater number of animals into existence. (shrink)
