I don’t think lions eating zebras is a good comparison.

We have evolved and flourished with agriculture and so we don’t have to consume meat unless the agricultural produce has gone way down.

I also think the general argument is how animals are treated with so many horrific videos out there which are just torture in my opinion and not a clean kill.

If someone is doing a clean kill without the animal suffering and making sure it’s living in good conditions, that’s a right step in many ways.

We can't survive without Vitamin B in various forms, which is not found in plants at all (some fermented soy products do contain some, but it's incorrect to say we evolved to not eat meat).
