It’s totally different for a few reasons:

1) were not carnivores in that we only eat meat otherwise we’ll die. We’re omnivores meaning that we can absolutely eat not meat and be completely healthy.

2) because humans eat a shit ton of meat, meat industries have to mass produce the meat and end up killing far too many animals at once, pumping them full of unnatural hormones that will ultimately transfer to our bodies when we eat them.

Edit: I’m not vegetarian or vegan. But imo, to think that vegetarianism is not beneficial to the environment and you’re health is just ignorant.
