Here's a page of "Top 45 Animal Advocacy Blogs."
I'm reading Simon Fairlie's book Meat: A Benign Extravagance....a very, very detailed book about the environmental ethics of meat. Rhys Southan has a long review. What I have learned from Fairlie so far: it's amazing how a cow takes grass, which we can't eat, and turns it into something we can (apart from moral scruples) eat. Well, it is amazing.
Not sure if I already put a link to Glass Walls here--PETA's latest meat video. I think it's excellent, even if not utterly perfect. But what's perfect? A student of mine said everyone should see it. She's right--so here it is. Pass it on.
