When was your grandfather born? He and his generation may very well have been eating what today is labeled "organic food". Factory farming is a relatively new phenomenon that has swept the country in only recently, and with phenomenal speed. >> In the 1930s, 24 percent of the American population worked in agriculture compared to 1.5 percent in 2002; in 1940, each farm worker supplied 11 consumers, whereas in 2002, each worker supplied 90 consumers.[23] >> The number of farms has also decreased, and their ownership is more concentrated. In the U.S., four companies produce 81 percent of cows, 73 percent of sheep, 57 percent of pigs and 50 percent of chickens.[24] In 1967, there were one million pig farms in America; as of 2002, there were 114,000,[25] with 80 million pigs (out of 95 million) killed each year on factory farms as of 2002, according to the U.S. National Pork Producers Council.[23] From: http://en.wikipedia.org/wiki/Factory_farming http://en.wikipedia.org/wiki/Factory_farming And that wiki article is missing a lot of information that's mentioned in Pollan's book and the film Food Inc.
