The morals regarding vegetarianism vs. omnivorism are very interesting. Here are some immutable facts...
1. Humans are instinctively hard-wired to seek sustenance from both plants and animals.
2. Humans are capable of saying "no" to their instincts, unlike pretty much every other animal.
3. Humans have the dietary knowledge and technology to survive without eating meat of any variety.
From a pragmatic standpoint, the debate should anticlimactically end right there. Do we want to eat meat? Yes. Can we be blamed for wanting to eat meat? No. Do we have to eat meat to survive? No.
But then morals get involved. Is it RIGHT to take a life that could have been spared, even if it's for a useful purpose? Who the hell knows?
Here's MY question...Why are some animals considered morally off limits for our diet? Why am I a weirdo if I eat a stray cat that I find outside? What if I WANT my tuna with a little smack of dolphin in it?
If a bald eagle drops dead on my front yard, is it right to eat it for dinner? These are the questions that keep me up at night.
