ETA: It's remarkable how much of what I put in my original post below has already been touched on by others here while I was writing it. I guess I should have checked to see what had been posted in the last half hour before I hit Submit, but whatever, I don't want all that typing to go to waste
:
I was once a faithful and sincere (though occasionally reluctant) vegetarian for about five years. There was no one reason why I became a vegetarian and no one reason why I went back to being a meat eater, so to get into the details of it would take too long and probably veer into derail territory. Suffice it to say that I think I can see both sides of the argument.
While I believe that vegetarians/vegans are more right than wrong in their beliefs and motivations, I also think that they have to get their stories straight when they are trying to convert others to the cause. There's a bit of contradiction in their stance that seems to boil down to this:
1. Humans, being animals themselves, have no claim to any sort of "high ground" (moral or otherwise). So saying "it's OK to eat animals because God said so" or "it's OK to eat animals that aren't as intelligent as ourselves" doesn't cut it because we are no "better" (in the cosmic scheme of things) than a chicken, cow, fish or pig.
2. Animals (i.e., animals other than the animal known as "human") eat other animals at worst as a necessary evil. Humans being the intelligent, broadminded species that they are have found alternate forms of nutrition and are no longer reliant on other animals for sustenance which means that they are morally obligated to abandon meat eating entirely.
I've found both of these arguments used side by side by vegetarians who seem blissfully unaware that there's at least a partial contradiction between the two. Are humans (in some senses, anyway) "superior" to other animals or aren't they? If they are, why can't they see that humans
are in fact slowly (arguably
too slowly) progressing from omnivore to herbivore? I'd argue that there is a greater proportion relative to population of vegetarians in the world than there has been in any point in history. Vegetarians who are so by choice, rather than it being forced upon them by the simple fact that there are no animals to be had. There are millions of years or evolutionary conditioning that hardwire a human's love for meat. That kind of conditioning can't be overridden across the entire species in a few decades. Many vegetarians are so simply because they don't like the taste of meat. I don't eat fish, not necessarily because of any superior morals, but simply because I
hate the taste of fish, always have. There are other factors that go into my decision not to eat them, like the fact that many species are being fished into extinction as we speak, with grave consequences for the ocean's ecosystem. If I'm honest with myself though, I acknowledge that the
main reason I don't eat fish is I simply don't like to, which means I don't exactly hold any superior moral high ground with my "no fish eating" stance.
If humans
aren't in any way "superior" to other animals, why isn't a human eating a salmon the same "necessary evil" as a bear eating a salmon? If a bear is offered the choice between a fish and a granola bar, is it being "immoral" if it chooses the fish?
Let me be clear here, lest vegetarians think I'm some omnivore apologist: I believe that if the human race is going to evolve and prosper, it will
inevitably (whether its 50 years or 500 years from now) become more or less completely vegetarian. There will come a time when our descendants will look back with disgust on us eating (cooked) meat as
we do with relative disgust with our earlier ancestors who may have eaten raw carrion.
Whether the planet's ecosystem can weather our long, slow evolutionary "learning curve" from omnivore to herbivore (or some completely synthetic form of nutrition?) is another question and the sort of question that vegetarians should pragmatically focus on
in the short term. In other words, they are more likely to get people on their side by talking about
sustainability (e.g., tighter regulations on commercial fishing) and environmental impact in general (livestock consuming water and food that could go to people. Or the fact that cows add greenhouse gases to the atmosphere) than they are by trying to talk others into quitting their meat eating habits, uh, "cold turkey".
