"I find it hard to care about the growth hormone at all, since it does not travel into the milk anyway, even if the cows are treated. Why should I care at all?"
Because what is done to these animals - whether it is a cow producing mike or a pig you will eat - effects the nutritional value of the resulting food, which in turn effects your health and well-being. Just one example is that the nutritional profile of the beef we eat has changed dramatically in the last 50 or so years because of the change in farming practices (basically, the amounts of omega fats in meat).
