Well I for one care about the treatment of other living creatures especially when weighed against what is essentially a luxury product.

If you're really concerned about the living conditions, you'd want more expensive, better quality milk.

I think we'd be better of, as a first step, ending subsidies to dairy farmers and enforcing some basic health and humane regulations. I mean, there are many dairy farms where discarded chicken meat and feces are fed to dairy cows. Here's a story about a guy feeding doughnuts and cookies. http://www.cheeseslave.com/farmer-feeds-doughnuts-and-cookie... Cows have very specialized digestive systems meant for processing grass. Even if we grant that cow's milk is a good thing for us to have, certainly it doesn't apply with diets like that.
