Why I Don't Eat Mammals
2007-03-14: Pig Out http://www.nytimes.com/2007/03/14/opinion/14niman.html
Of the 60 million pigs in the United States, over 95 percent are continuously confined in metal buildings,
including the almost five million sows in crates.
In such setups, feed is automatically delivered to animals who are forced to urinate and defecate where they eat and sleep.
Their waste festers in large pits a few feet below their hooves.
Intense ammonia and hydrogen sulfide fumes from these pits fill pigs’ lungs and sensitive nostrils.
No straw is provided to the animals because that would gum up the works (as it would if you tossed straw into your toilet).
