Just because we can doesn't mean we should. Just because we always have doesn't mean we always have to. Once we know better, we should choose better.

Perhaps the most heartbreaking are the lives of the cows who are repeatedly impregnated in order for us to serve milk, cheese, butter, ice cream and other dairy products.  Their distress is seen for days after the awful event.  These generally docile beings become aggressive when their calves are pulled from them during the birth.  Then, the calves are taken to small pens and chained up so that their muscles cannot develop.  Their muscles need to stay white and pale for "velvety" veal when their lives are ended at 18 weeks.  Even after such a tortured childhood, not being able to run through green pastures, not even this living creature yearns for death.  And all of this happens to create totally unnatural food choices.  Let's wean from our own mother's milk and move on to adult food.
