Milk... Hmm. Although I'm not a vegetarian/vegan myself, the way we obtain milk
is pretty dodgy... For one, the cow has to have had a calf to produce milk (and keep producing calves to produce it for however-many-years she'll be used for her milk for) so there's lots and lots of unwanted calves produced every year (most get sold for continental veal, I believe...?). And I vaguely remember reading somewhere that their udders are often so distended with the huge load of milk they have to carry before being milked makes it painful to walk. There was something about hormones as well, but I can't remember what it was... Hm
