Of course, it is useful to know how are tortured livestock and how overfishing destroyed entire species, but enough is enough! by the middle of the book, I closed with a feeling of lassitude: it's really too redundant! not recommend to readers who want to make a precise study on the subject or to people who want to become vegetarians and have trouble letting go their steak. Guaranteed disgust. Too hard to drive the point ends up hurting. Pity.
