This is kind of an old discussion. I'm perfectly happy eating meat but equally recognise that vegan diets are perfectly feasible for almost everyone. If not vegan, then vegetarian (preferably with a premium on animal products to reflect their impact etc).
A nice example of this is omega 3 and similar: it is actually synthesised in kelp and works its way through the food chain to us with fish as an intermediary. It doesn't have to be that way, it just is right now. B vitamins are a similar story.
