Hypothetically, yes. But that's extremely unrealistic. I'm sure world peace and an end to poverty would be nice, too, but it ain't gonna happen.

Lean meat is healthy in moderation, but not as healthy as fruits and vegetables in any-ation.
Not true. Lean meat is healthy, period. True, if you base your entire diet off meat, you won't be able to get EVERY nutrient you need, but you could live just fine for quite some time. Hell, liver has more vitamins and minerals than you could imagine. And some fruits and vegetables, if you base your diet entirely off them (or fruits and vegetables as a whole), you wouldn't get everything you need. So fruits and vegetables are healthy, yes, but no more healthy than lean meat, honestly.

People less ignorant would argue that humans being excessively cruel to animals is an issue today, and a major one.
People less arrogant would argue that humans being excessively cruel to animals is nowhere near a major issue today. Mind your tongue.

edit ShinNakamura; There was a reason our neandrathal ancestors had a gall bladder, an appendix, and sharp eye teeth. It was to aid the process of eatong meat, no doubt. But we've evolved boyond that, and we no longer require meat in our diet.
Another problem with Evolutionism. What evolved first, the diet or the "equipment"? Why would humans evolve different organs to digest different foods? Why would humans evolve different diets to be better digested by their organs?
