I agree with you that it alot of thing in the world is not okey, eating meat, however, is not one of them.
No animal (including humans) are all good. I would, as you (I hope), like to live in a better world. A better world for me is a world less poluted, with wilderness left for us and other animals to enjoy.
However, breading animals for food purposes doesn't destroy the world! It's more everything else we do, including the population growth (maybe the biggest factor). We need to stop it, and alot more of the "bad" things we do. I think it is our intellegence that really is the cause to everything bad. We do alot of more things (usually bad) than we need for just survival (as the most animals).
I still think we have more value than other "lower animals" (evolution ladder), but we (in order for our own survival) need to take care of the world much better than we do today.
So partly I think that we agree. Thank you for a good view. I understand your point of view, even if you don't understand mine.
