The ethics of food-10: Minimizing suffering
(For other posts in this series, see here.)
The theory of evolution says that we are all connected in the tree of life. So humans are not only related to apes and other animals, we are also related to plants and even to the 'lowly' fungi. But no one is arguing that therefore we should stop eating vegetables too.
Clearly to survive we have to draw at least some lines as to what species we include within our moral community and what species we exclude. Such lines are necessarily arbitrary but need not be without some justification.
If we are going to use suffering as the measure of whether we are justified in killing and eating animals, then that implies that sentience is a key marker. But what level of sentience? Peter Singer and other animal rights philosophers argue that some level of sophistication of the nervous system is necessary to include the species within our moral compass. They draw the line at the nervous system of scallops, so that anything with an equal or more primitive nervous system than a scallop can be eaten.
Michael Pollan in The Omnivore's Dilemma (2006) points out that a purely vegetarian diet does not solve the problem of killing animals.
Killing animals is probably unavoidable no matter what we choose to eat. If America were suddenly to adopt a strictly vegetarian diet, it isn't at all clear that the total number of animals killed each year would necessarily decline, since to feed everyone animal pasture and rangeland would have to give way to more intensively cultivated row crops. (p. 326)
From this he draws a surprising conclusion:
If our goal is to kill as few animals as possible people should try to eat the largest possible animal that can live on the least cultivated land: grass-finished steaks for everyone.
. . .
Indeed, it is doubtful that you can build a genuinely sustainable agriculture without animals to cycle nutrients and support local food production. If our concern is for the health of nature – rather than, say, the internal consistency of our moral code or the condition of our souls – then eating animals may be the most ethical thing to do. (p. 326)
It is undoubtedly true that in the competition for land, food, water, and other resources to maintain life, humans are unavoidably, even if indirectly, causing the death of other animals, whether we eat them or not, and even causing damage to the planet as a whole. (There is a group called The Voluntary Human Extinction Movement that argues that to reduce suffering and for the health of the planet, humans should choose to not have any more children and thus eventually become extinct.)
While the above arguments can be used by meat eaters to justify their continued practice, we should be wary of being too easily persuaded by them. It is always the case that people can usually come up with reasons to justify whatever we want to do, and meat eaters are no exception, especially since the desire to eat meat is so strong. Benjamin Franklin pointed out that "So convenient a thing it is to be a reasonable creature, since it enables one to find or make a reason for everything one has a mind to do."
Singer cautions that it is hard for meat eaters to really understand the case against eating animals. He warns that we meat eaters cannot really be objective about this question because of the strong rationalization tendencies that come into play. "We have a strong interest in convincing others that our concern for other animals does not require us to stop eating them. . . . No one in the habit of eating an animal can be completely without bias in judging whether the conditions in which that animal is reared cause suffering." (Pollan, p. 313)
Singer's argument about the danger of self-deception impressed writer Pollan so much that he became a vegetarian while studying this question so as to try and increase his objectivity. He reverted to eating meat afterwards, though. (As was pointed out by commenter Dave to an earlier post, those who decide to adopt a vegan, or even vegetarian, diet need to find ways to supplement their diet with the essential vitamin B12, which is normally obtained only from meat and dairy products.)
Wherever one finds oneself in the debate of whether it is ethical to eat meat or not, I think that we can probably all agree that animals should be treated well while they are alive and that if they are to be put to death for whatever reason, it should be done in as humane way as possible in order to minimize suffering.
But it is clear that even this very limited goal is not being met. Our present industrial-scale food production system (more on this later) not only treats animals extremely cruelly, it pollutes the environment, destroys the soil, and poisons everything.
When I was very young and passing through my phase of infatuation with all things cowboy, my parents gave me an air rifle for my birthday. Excited, I wandered through my aunt's backyard in northern Sri Lanka, shooting and missing at all kinds of targets, while imagining myself as one of my cowboy heroes. Seeing a crow in a tree, I aimed and fired, never dreaming that I would hit it. To my surprise, the bird dropped like a stone, dead. Soon after, the sky was filled with other crows making a terrific racket, which I took to be them rebuking me for this wanton act of destruction. My horror at the experience of having personally killed an animal and causing what seemed like great grief to other birds resulted in my only shooting at inanimate targets in the future.
There is a person who works for the maintenance department at my university who once a year gets a license to hunt deer and spends a weekend in the woods to shoot an animal. He has described his experiences to me. There was a time when my childhood experience with killing an animal would have resulted in me considering this a blot on the character of an otherwise decent person, treating him as the equivalent of the killer of Bambi's mother. But now I realize that by buying meat that is produced by the industrial farming production system, I am guilty of more inhumane behavior than he is, because the animal he kills and eats has likely lived a far better life than the ones that I buy from the supermarket freezers.
