Jonathan Safran Foer is here as a writer and journalist; he surveyed breeders, hatcheries, slaughterhouses, pro-animal activists too; what he discovers is devastating. This book is the journey of awareness of any vegetarian. Because become a vegetarian it is a path, long and full of relapses, a path from indifference to reach the conscience and morality, and empathy. Starting from his personal history of grand-son of Jewish immigrants, the history of American migrants and their traditional Thanksgiving, Jonathan Safran Foer will invent for her baby son still its own festive and social tradition, no turkey on the table, breaking with the storytelling carniste hunters and conquerors. We are what we eat. Our societies would be more peaceful without slaughterhouses where no "human" treatment of animals is possible. We can well do without meat, and 9 billion more on the planet, eating is folly for us, animals and our environment.
