Which tribe is vegan?

I'm curious to know, could you elaborate on which specific tribe you're referring to when you ask, "Which tribe is vegan?"? As there are numerous tribes across the globe, each with their unique cultural practices and dietary habits, it's not immediately clear which one you're inquiring about. Are you asking about a particular indigenous group or a tribe that has adopted veganism as a way of life? Providing more context would help me give a more accurate and informative response.
