I have steered clear of this thread by my controversial comments in another thread...
I think the Native Americans had it right in regards to their treatment of a "kill." THey showed respect and gave thanks to the animal that has provided them a couple more weeks without starvation. Of course, times are quite different now but you get the idea...
I come from a very "machisimo" family of BIG hunters and in my childhood, I hunted quite a bit. These days, I go very rarely and to be honest, I do not really enjoy it. However, with me, there is some sort of monetary importance to hunting. I make VERY little money and so I venison or turkey or dove/quail meat is always in my freezer. With the price of beef these days and my very minimal graduate school income, this is a good way to save money (plus, I like the way it tastes).
I think hunting can be done in as ethical a fashion as killing a cow in the slaughterhouse (which I have unfortunatly had to go to almost once a month for the past year and a half). I do know hunters that hunt only for that trophey but almost all I know are really upset if the kill is not "clean."
As far as it being more humane than what goes on in nature, well, I guess that involves a bit of anthropomorphication. In fact, I have heard different points of view from different biologists (and some philosphers) on the matter and the argument pretty much falls in line with this discussion here on RS.
A interesting philosophical argument that is always made (and a valid one) is to hypothetically assume that a higher lifeform from a different planet landed on earth and began to "harvest" the inferior humans as food. While the gaps in this argument are fairly obvious, it does make a pretty good point.
Interesting that this topic also appeared in my Vet school application a couple of years ago. To preface, it essentially asked how I (or any vet) can justify helping to preserve the life of client A's poodle while also helping out the beef, pork, and poultry industries. Again, you can see the obvious "loopholes" in the question but the underlying philosophy behind the question really is tough...
Just some thoughts...
Take er easy
