Veganism?

[Diamond]

Well, if one person is willing to listen (or, technically, read) then I guess it's worth a try.

You have evolved to be an omnivore and you should ONLY consider veganism for medical reasons or you were born and raised on it. To switch from an omnivorous diet to vegan diet in a short period of time is dangerous to one's health.

This is a new one, but it's not entirely true. There are plenty of cases of people going from omni straight to vegan. The *only* down side to this is that it may cause someone to go back to eating eggs and dairy as it takes a lot of willpower just giving up meat alone. There's really nothing to worry about in regards to health.

Is a lion "immoral" because it kills and eats a zebra?

No. But this argument is irrelevent as animals don't have the same idea as humans in regards to "morality". I mean, c'mon, there are some animals that eat their own young.

So the question is, if we aren't supposed to eat animals, why are they so dang tasty?

Have you even eaten meat that wasn't seasoned, fried, or drizzled in sauce? I have. It's worse than chewing on cardboard.

If humans were adopted to a purely or even largely vegetarian diet, humans would have small chests an an enormous distended belly with miles of digestive track in which plant matter can linger and ferment, sort of like cows, or like gorillas with their cone shaped rib cage sitting atop a big sack of a belly.

They do. Not miles, but our digestive tracts do match those of natural herbivores. More information here.
