Virtuoso, well, that question really depends on how you define "natural".
Biologically we can on the whole get away with eating animals, albeit at the expense of diminished health.
Morally, as enlightened human beings who no longer live in a subsistence situation or in the stone ages for that matter, I think it's totally repugnant to mass breed animals in factories with the sole purpose of eventually brutally killing them - animals of which many like pigs are far more intelligent than dogs but with the same feelings, inherent playfulness and ability to feel pain and fear etc - breeding them in contemptible, confined surroundings totally at odds with their natural life style, condemning them to a miserable life of permanent fear, total misery and pain, which is ended in an even more painful and barbaric way, just so we can then eat them.
And as I mentioned earlier, after you get your head around the decision itself, life afterwards will be far superior in many ways, and you really will not miss anything.
That is really true, it's just in your head.
