Stewardship is right. Dominion is a deliberate mistranslation. None the less, humans are animal and I view other animals as my kin.
That I couldn't do, as I like meat, and I know that they were put on this earth for our use. For me to consider an animal as my "kin" that would make me a cannibal. We hold dominion over every living thing. We ARE at the top of the food chain. Now I'm not saying that we have done a bang up job when it comes to our stewardship of those that He gave of us dominion over, but the fact, imo, is that is what they are here for.
