We are what we are, and what we are is a species of omnivores with a strong lean towards the carnivorous. Why, pray tell, should we be so ashamed of the reality of ourselves that we deny ourselves the right to be what we biologically are? To do so is dangerous when living in an unpredictable world... even if it seems a good thing to do at the time.
Nothing like an appeal to nature. I've been in scientific and skeptical discussions for years, and routinely I've seen the appeal to nature argument to shot to hell and back. It comes up over and over and over in a variety of masks:
"
Homosexuality is not natural as it is not used for reproduction, therefore it is immoral and homosexuals are bad."
"Transgender surgery is wrong an
unnatural, gender is determined by biology."
"Vaccines are dangerous,
natural remedies are better."
Radiofreethinker skewers a version of this.
"
The natural world is characterized by competition; animals struggle against each other for ownership of limited natural resources. Capitalism, the competitive struggle for ownership of capital, is simply an inevitable part of human nature. It's how the natural world works."
"Does not the very nature of things teach you that if a man has long hair, it is a disgrace to him, but that if a woman has long hair, it is her glory?"
1 Cor 11:3-15
"
Survival of the fittest implies that "might makes right" is a proper guide to behavior. /
Darwinism leads to social Darwinism, the policy that the weak should be allowed to fail and die.
The
Unabomber Manifesto is an appeal to nature which rejects technology entirely.
Skepchicks shredding another variant of the naturalistic fallacy in response to fears of processed food, or homogenized milk in particular.
How many of those arguments are familiar to you? At least one or two, right? I hope its obvious why appeals to nature are fallacious: the terms "natural" and "unnatural" are loaded terms, in that they have connotations with "good" and "bad" respectively. "Natural" and "good" are not in fact synonyms, there's no necessary connection between them at all:
Natural and bad: Hemlock, tornados, tsunamis, malaria, the state of nature itself are all found in nature..
Natural and good: Wood, water, light, oxygen, and cannabis are all found in nature.
Unnatural and good: Plastics, skyscrapers, organ transplants, Ladytron, and transistors are quite manmade.
Unnatural and bad: Water boarding, pipe bombs, asbestos, thalidomide, and smog are also manmade.
Its not exactly clear what you find so persuasive about appeals to nature when applied to eating meat as opposed to equivalent arguments that are applied to homosexuality. Regardless of the obvious fallacious implications, appeals to nature are no more friendly to animal rights than they are to human rights. See

Dessi said:
evolution not a noramative moral theory. Even if it were, its certainly not a human rights moral theory, since its
wholly consistent with evolution to compete with members of your own species. We are equally justified by evolution cooperating with our own neighbors as we are enslaving him and harvesting his property and organs for our own use. On a grander scale, slavery and ethnic nationalism can be defended by the very same "biologically determined imperatives" to maximize the survival of ourselves and immediate population. Of course, no one takes those arguments for social darwinism seriously because
because evolution is not a moral theory -- its descriptive, not prescriptive.
The same appeal to nature justifies killing animals as much as killing humans. That's kind of the point of this thread: animal rights and human rights are two sides of the same coin. Arguments against one are arguments against the other, arguments for one are arguments for the other. As soon as we concede that we ought to treat humans with any respect at all, rather than compete against them for our own advantage, we've already "denied what we biologically are." If you can understand that much, then you can understand that the phrase "humans are omnivores" has absolutely nothing to do with how we justify our diet. If we can minimize the harm that we cause, we should do that much.
I can understand why people fall back on appeals to nature -- because they're so damn convenient and easy -- but in all seriousness, this is the JREF, its a site for skepticism and critical thinking. You don't have to be an animal rights activist to spot the immediate error in the statement "humans should eat meat because that's what they do".
