Abstaining from killing animals is about the sober realization that we can have perfectly healthy and happy lives without killing animals, who have feelings and a sense of perspective and experience, just like us. Living with my values and actions as one give me a strong sense of life, and I love cooking every day. Plants taste great when cooked well!
But I have enough hobbies and I don't want to risk missing some things we don't yet know about. I just eat what I evolved to eat.
> I just eat what I evolved to eat
So do I: plants!
I'm an omnivore. all meat or no meat is not what i'm evolved to eat. Perhaps I eat too much meat, but zero meat isn't the right answer.
