Im going to move on from the eat insects thing because I think you've failed to see the original point and we're moving into offtopic territory anyway, and I dont advocate the eating of insects anyway. I dont kill bugs if I can help it at all.
We never evolved "away from" eating human flesh, because we never really did. Cannibalism for food wasn't the norm back then, nor is it ever in nature. Only by exceptions.
Our ancestors did eat our ancestors. A lot of animals also do practice cannibalism. Lions, some monkeys, snakes, sharks, etc.
Still, this is all beside the point, you're arguing side points instead of the main issue; that humans do not need to eat meat to survive, that we can live without it, that we have the means, that animals suffer when slaughtered and that it is morally wrong.
Regardless of that, I never disagreed that a lot of bio-industry is being poorly run and that we can do better. I also agree that in a typical Western diet, meat consumption is disproportionately high. But the "suffering animals" as a claim against eating meat in general is a very, very slippery slope.
How is it a slippery slope? It is the truth.
Anyway Im out for the night, you'll have to excuse me it is my three year anniversary, so someone else will need to take over.
No, because I place my own kind first. I value human life more than animal life.
So do I, but I also value animal life, and faced with healthier and smarter alternatives I just cant justify eating meat.
