The ethical arguments here are very interesting. However, I'd like to deal with a couple of the dietary myths relevant to this thread.
First from Jacob's original post:
JacobSpinney:
... There is no longer any nutritional need for consuming animals in todays society ...
I'm aware that the essential animal-source vitamin can now be produced artificially. However, it is becoming increasingly apparent that what scientists have been able to determine in their laboratories about human nutritiion is only the tip of the iceburg. There is an incredible amount of value in getting one's nutrients from food rather than simply taking a pill that supplies the recommended daily requirements of the vitamins and minerals scientist have identified. If this were not the case, then all our food could be created atificially.
Second, a couple of people have mentioned the health benefits of a vegetarian diet. These supposed benefits appear to be the result of the media's selective publication of studies that support this view, while ignoring studies that oppose it. I read quite a bit about The China Study on this issue. My conclusion was that the researchers involved where looking for support for their hypothesis that vegan was better -- a hypothesis they developed by doing research on rats not humans. From what I could see they fudged the data to support this conclusion.
The bottom line for me is that over the past million or more years, people have eaten a mix of animals and vegetables. Hence, this is what people should be eating if they wish to maintain optimal health. I realize this means killing animals (and plants) in order for us to survive. (As well, no doubt, as uncounted numbers of lower lifeforms -- both animal and plant.) That's just the way it is.
The alternative for me is to kill off all life on earth.(If you take the arguments of most environmentalists to their logical
conclusion, that what they're recommending. So, hey, a lot of
people support that alternative.) I mean if we should refrain from killing animals for food, doesn't it follow that we should stop other animals from doing so as well. And of course there's still the question of where you draw the line -- how much do plants feel. It all just snowballs from there. (Sorry, I couldn't resist a little bit of philosophy.)
