Kumar, here's a bit of a thing to chew on.
I mentioned before that a bee, when it stings, disembowels itself and dies. And yet, I think it safe to say that bees are not idiots. They are bees, and bees, like many animals, do not think as we do, do not have our values, and if there were anything that a person mistakenly thinking his metaphors have ontological importance might call values, they would be those of the hive and of the species.
Why might that not be true of other animals too? Take cows for example. It is true, of course, that we eat cows, but are they fools for coming back to the barn? There are many many many more cows living and mating and eating and sheltered from the rain than there ever were wild cows. In fact there were no wild cows, only aurochs, and they are extinct. You, in you human-centric way, say cows are the fools but cows as a species are flourishing, but the aurochs, even more than the flower fed buffaloes of the spring, roar no more and trundle no more.
This is, of course, a little bit facetious because I think your whole argument and attitude are so far from reasonable that they are immune to reasonable argument, but why not think a bit about the bargain here? The death of individual cows matters only if cows value individuality, but who is to say they do? Bees and ants, it seems, do not. What cows have you interviewed to substantiate your point of view? Thinking in terms of the species-wide, or even the herd-wide bargain, the cows are doing pretty well.
