Can
science help us resolve our ethical dilemmas? (Let us forget all the dilemmas
that it creates... for the moment.) According to a recent New York Times op-ed by Adam Shriver, the
answer would appear to be “yes.” Scientists have been able to isolate the gene
for a peptide critical to the functioning of the anterior cingulate gyrus
(where the mammalian brain perceives pain) in mice. As Shriver explains, if the
functioning of the anterior cingulate gyrus is affected, the brain can still
perceive pain, but it no longer translates the feeling of pain into something
unpleasant. Given our successful track record in the genetic modification of
animals, it seems inevitable that scientists will eventually be able to
genetically engineer mammals – say, pigs or cows – without the ability to
perceive the unpleasantness associated with pain. Should this happen, it would
seem that science will have gone a long way toward resolving the thorny ethical
issues surrounding the pain and suffering that animals endure on their journey
to our dinner tables (particularly when they are produced in factory farms or
confined animal feeding operations, CAFOs). So, is it possible that in the next
few years places like Whole Foods will be offering grass-fed, omega-3 enriched,
pain-free ground beef? Better yet, the Happy Animal Happy Meal at McDonald’s?
Perhaps.
I must
admit, when I first read of this line of research, I thought, finally, I can
enjoy a bacon-wrapped hot dog without being wracked by guilt (or at least only
guilt regarding my own health, but that’s a guilty pleasure). However, before
we jump to the conclusion that vegetarianism is dead or that we no longer need
to modify “omnivorism” with “conscientious,” let me offer a few thoughts, some
of which I hope will speak to the larger relationship between science and
ethical dilemmas.
First,
even if animals can no longer feel the pain that they endure, can they still
suffer? Would it be morally excusable then to “dock” pigs’ tails or confine
calves for veal production? Do these practices become humane now that the
animals cannot feel pain? These issues, largely related to animal welfare, seem
to remain unresolved with the development of pain-free meat. What of the other
concerns associated with factory farms? How will the practices of producing
animals change when they are pain-free? Will there be a need for animal welfare
laws? With animals pain-free, a limit to
production efficiency would be lifted. Pigs and cows and chickens would be able
to be packed together more tightly and slaughtered with greater speed. How will
this affect the quality of meat products, human health, environmental
conditions and emerging concerns over antibiotic-resistant
bacteria and superbugs from factory farms? What of the workers? Will
knowing that the animals are slaughtered without the unpleasantness associated
with pain in some way address serious concerns over working conditions in
factory farms?
These
questions are not answered by our ability to affect or direct the functioning
of the anterior cingulated gyrus. Shriver, in an article in Neuroscience (and discussed in the New Scientist), sees this not as a
solution to factory farming but as a way to avoid animal suffering associated
with the practices involved in factory farming. While he concedes that factory
farming practices leave much to be desired, he is arguing that the ability
to raise livestock without pain may absolve these farms of what many see as their
ethical wrongdoings. This may or may
not come to be the case. Clearly, other ethical issues remain. In fact, it
seems as if the science ends up raising as many (ethical) questions as it
answers. This is something, perhaps a principle of sorts, that we should be
mindful of as biotechnology, nanotechnology, and other areas of research
pushing the frontiers of modern science and technology ever forward become
increasingly present in our lives. We cannot and should not expect science and
technology to solve the ethical issues that we, often with the use of science
and technology, have created. Only through the painful process of politics can
we hope to resolve these issues and find the areas in which science and
technology may be effectively applied to help us grapple with such concerns. Or
perhaps we can just wait for petri-dish
raised beef to finally absolve us
of our guilt from eating animals (but would it?).

Shriver's article, although provocative, is misguided...I would go as far as to say that it is quite dangerous. Like you said, to suggest a technological fix to the moral issue of animal suffering in slaughterhouses is seductive, indeed, since so many animal welfare advocates oppose industrial farming (and also animal research) solely based on the cruel treatment and misery of animals, and not their imminent death.
But before embarking on such a journey, one needs to think carefully of the repercussions, the least of which is how farmers and businesses would transition into the buying and selling of pain-free animals. As you mentioned, removing the genes that allow pain receptivity may precipitate a regression into business practices that have been opposed by a largely white, middle-class, and educated population. If animals cannot suffer, then the best practices of industry have a good chance of deteriorating. (Europe, in particular, has gone great lengths in their policies on animal treatment, such as increasing the size of chicken coops and making it possible for sows to turn around in their crates.)
Unfortunately, I do not think the threat of pain immunity and its implications for humans is a very good argument against such manipulation. So many technologies are applied to animals and not humans (cloning, spaying and neutering). Although there may be some lobbies that want pain immunity technology for military use, competitive sports and chronic disease, I can easily see swift regulation from on high. I can even see a new spin on the cliche, "You know you're alive if you can feel pain." But, of course, there is always the possibility that what technology was developed to ease suffering in slaughterhouses can jump into societal use and produce a whole slew of unintended consequences.
The relationship between human and animals is a very complicated one, to say the least, one paradoxical in the necessity of instrumental use and guilt that accompanies it. So people should be talking about it in true democratic fashion. What is the ethical treatment of animals may not be moral.
