Gotta' feed the masses! The majority bases purchase decisions on price over any other factor, whether that be quality or even ethics. Thats why factory-farming of animals has developed to the point it is now.
If you really
want to see something gross, look up the conditions and environmental impact of Smithfield Pork farms in the Mid-Atlantic states. I refuse to purchase Smithfield pork products for this reason, and the fact that they are almost all packaged in a salted broth to plump the meat and extend it's shelf life. It's cheap, but not better in my book!
But mass farming is what it is. I bought a couple 3lb chickens this morning for $2 each. I can't believe there are even any profits in that! It's that streamlined process that enables the high volume and low prices.
I don't think I could ever become a vegetarian though. And unlike that article states, I'm in no way drifting from red meat eating!
