All four of us have read the book -- loved it!!! It's the one title we recommend to anyone who expresses an interest in learning more about the subject. Without being overly technical and/or preachy, Jonathan Foer does a superb job of presenting the issues involved in factory farming. After the birth of his first child, he began wondering about the sources of the food they were eating. That curiosity, combined with investigative work and personal stories morphed into a wonderful read.
For those interested, here's a link to info on the book.
