This is where bacon comes from. This is a factory farm. Over 95% of our meat comes from factory farms. A package of bacon might show a red barn, green grass and happy animals, but this is what the farm actually looks like.
Does anything justify this?
Serious question. In my personal opinion, no, but I'm wondering what others think.
Somebody thinks this is justified, because we eat 120,000,000 pigs every year in the US. (http://www.ansc.purdue.edu/faen/Pork%20Facts.html)
