On a tour of the world to understand the mechanics of globalization, Erik Orsenna and Dr. Isabelle de Saint Aubin turn their attention to our relationship with animals, and in particular with pigs, the most-consumed animal in the world. They show how these creatures, who are in fact so similar to humans, have borne the costs of our globalized world, and how, in a vicious circle, raising them contributes to the destruction of the natural habitats of wild animals. Everything is connected, and through the pig, we learn about the unity of all life.
