I am a mere vegetarian but I justify it by aiming for generally better, not perfect.

(Also I adopted my cat about a decade before I became a vegetarian, it doesn't seem morally superior to destroy her because I had a change of heart.)

I see. I eat meat and I know about the issues (health wise and environmentally). I’m trending towards less, largely for health reasons.

My ideal world (in my head) is that human beings don’t interfere with animals at all (to eat, as pets, to showcase). We should interfere in only cases where it’s critical (like a natural disaster treating animals).

Is there a word for this viewpoint?

I live with and care for a dog. We are coevolved species. Your frame of ‘owning’a pet is not shared by all.

If there is a word for it I don't know it, sorry.
