Most vocal critics of animal cruelty in industrial agriculture come from the Left, with arguments that tend to take the form that animals have "rights" in much the same way humans do, or that utilitarian calculi of pain/pleasure must take account of non-human animals as much as humans, since most non-human animals can feel pleasure and pain. One need not come at the issue from this perspective, however. In this essay, Christian conservative writer Matthew Sculley offers a thoughtful, passionate piece on why our current treatment of animals (particularly abuse of pet animals and food animals in industrial agriculture) is un

Now those religiously-based starting points of his argument may be problematic for some people (they are for me). But I don't believe you need to share Sculley's Christianity to agree with his basic argument--at least as I understand it. Sculley basic suggests--contrary to deep ecology and anti-anthropocentric arguments--that humans are "special creations" that are superior to non-human animals in critical aspects, but that this "special" status is not merely a conversation-stopping response about why humans can do whatever they want to with animals, but a conversation-starting recognition that with special status comes special obligations, specifically the obligation to treat animals without cruelty and in a humane and decent way. I think one could as easily agree with Sculley on the "special" status of humans without deriving that from a "special creation" account lodged in Christianity or any other religious worldview. One could, I believe, simply recognize that evolution/natural selection has "bestowed" upon us a special status--including consciousness and the ability to make true choices--that creates the obligations of which Sculley speaks. Now of course that evolution/natural selection may well be viewed as God(s)-driven as well (theistic evolution), but I think his view is flexible enough to take in perhaps more than sees.
In any case check out the essay. I'm currently in the middle of the book it is drawn from (Dominion...), which is well worth a read...
