Just to add to what Robert had to say:

If anyone thinks the cows are having a fun time, think again!

Anything, like the "Milk Industry" or the "Cheese Industry", that becomes big business does so by making feeling beings suffer. The cow's entire life is spent "producing" milk. And then, it's killed.

I am always amazed by the TV advertisements for milk, cheese and eggs. You never see a real cow or chicken that actually work in the "Industry". I wonder why that is?
