Ok, so tell me. We have these creatures called cows, right, and they moo and crap and everything. But if they don't milked regularly, it hurts them. It'd be mean to make them suffer, so we milk them. The cows are happy. Well, we can't just let the milk get all over the ground, so we put it in a bucket. So now we have this calcium enriched liquid that, when devoid of germs, tastes good and refreshes you in the morning. What do we do with it? We drink it. What else would we do with it, with earth's population rapidly increasing and the fresh water supply rapidly decreasing and nowhere to throw it all away? We drink it. We can't throw it in the ocean, if I were a fish I'd be annoyed by this stuff getting dumped in my water by the barrel every day.
