No. In the first place, the question assumes that we would not have devised alternatives to animal use if that were necessary either because nonhuman animals were not available or because we made a moral decision not to exploit them as resources. Second, even if animal use were necessary for society as we presently know it, the same argument could be made with respect to any human activity. For example, without wars, patriarchy, and other forms of violence and exploitation, we would not have society as we now know it. The fact that a given activity was a necessary means to what some of us regard as a desirable end does not prove that the means were morally justified. Present-day Americans would not enjoy the level of prosperity that they now enjoy were it not for human slavery; that does not mean that slavery was a morally acceptable practice. Third, there is at least an argument that our present-day society, with its violence, pollution, inequitable distribution of resources, and various forms of injustice is less desirable an end than some think, and that we ought not be so eager to endorse the means that got us where we are today.
Every form of discrimination in the history of humankind has been defended as “traditional.” Sexism is routinely justified on the ground that it is traditional for women to be subservient to men: “A woman’s place is in the home.” Human slavery has been a tradition in most cultures at some times. The fact that some behavior can be described as traditional has nothing to do with whether the behavior is or is not morally acceptable.
In addition to relying on tradition, some characterize our use of animals as “natural” and then declare it to be morally acceptable. Again, to describe something as natural does not in itself say anything about the morality of the practice. In the first place, just about every form of discrimination ever practiced has been described as natural as well as traditional. The two notions are often used interchangeably. We have justified human slavery as representing a natural hierarchy of slave owners and slaves. We have justified sexism as representing the natural superiority of men over women. Moreover, it is a bit strange to describe our modern commodification of animals as natural in any sense of the word. We have created completely unnatural environments and agricultural procedures in order to maximize profits. We do bizarre experiments in which we transplant genes and organs from animals into humans and vice versa. We are now cloning animals. None of this can be described as natural. Labels such as “natural” and “traditional” are just that: labels. They are not reasons. If people defend the imposition of pain and suffering on an animal based on what is natural or traditional, it usually means that they cannot otherwise justify their conduct.
A variant of this question focuses on the traditions of particular groups. For example, in May 1999 the Makah tribe from Washington State killed its first gray whale in over seventy years. The killing, which was done with steel harpoons, antitank guns, armor-piercing ammunition, motorized chase boats, and a $310,000 grant from the federal government, was defended on the grounds that whaling was a Makah tradition. But the same argument could (and is) made to defend clitoral mutilations in Africa and bride-burning in India. The issue is not whether conduct is part of a culture; all conduct is part of some culture. The issue is whether the conduct can be morally justified.
Finally, some argue that since nonhuman animals eat other nonhumans in the wild, our use of animals is natural. There are four responses to this position. First, although some animals eat each other in the wild, many do not. Many animals are vegetarians. Moreover, there is far more cooperation in nature than our imagined “cruelty of nature” would have us believe. Second, whether animals eat other animals is beside the point. How is it relevant whether animals eat other animals? Some animals are carnivorous and cannot exist without eating meat. We do not fall into that category; we can get along fine without eating meat, and more and more people are taking the position that our health and environment would both benefit from a shift away from a diet of animals products. Third, animals do all sorts of things that humans do not regard as morally appropriate. For example, dogs copulate and defecate in the street. Does that mean that we should follow their example? Fourth, it is interesting that when it is convenient for us to do so, we attempt to justify our exploitation of animals by resting on our supposed “superiority.” And when our supposed “superiority” gets in the way of what we want to do, we suddenly portray ourselves as nothing more than another species of wild animal, as entitled as foxes to eat chickens.
No, of course not. This question is logically and morally indistinguishable from that which asks whether those who advocated the abolition of human slavery cared less about the well-being of southerners who faced economic ruin if slavery were abolished than they did about the slaves.
The issue is not whom we care about or value most; the question is whether it is morally justifiable to treat sentient beings–human or non-human–as commodities or exclusively as means to the ends of others. For example, we generally do not think that we should use any humans as unconsenting subjects in biomedical experiments, even though we would get much better data about human illness if we used humans rather than animals in experiments. After all, the application to the human context of data from animal experiments–assuming that the animal data are relevant at all–requires often difficult and always imprecise extrapolation. We could avoid these difficulties by using humans, which would eliminate the need for extrapolation. But we do not do so because even though we may disagree about many moral issues, most of us are in agreement that the use of humans as unwilling experimental subjects is ruled out as an option from the beginning. No one suggests that we care more about those we are unwilling to use as experimental subjects than we do about the others who would benefit from that use.
No. The fact that we are in some sense responsible for the existence of a being does not give us the right to treat that being as our resource. Were that so, then we could treat our children as resources. After all, they would not exist were it not for our actions–from decisions to conceive to decisions not to abort. And although we are granted a certain amount of discretion as to how we treat our children, there are limits: we cannot treat them as we do animals. We cannot enslave them, sell them into prostitution, or sell their organs. We cannot kill them. Indeed, it is a cultural norm that bringing a child into existence creates moral obligations on the part of the parents to care for the child and not exploit her.
It should be noted that one of the purported justifications for human slavery in the United States was that many of those who were enslaved would not have existed in the first place had it not been for the institution of slavery. The original slaves who were brought to the United States were forced to procreate and their children were considered property. Although such an argument appears ludicrous to us now, it demonstrates that we cannot assume the legitimacy of the institution of property–of humans or animals–and then ask whether it is acceptable to treat property as property. The answer will be predetermined. Rather, we must first ask whether the institution of animal (or human) property can be morally justified.
