This book is an excellent advocacy argued for the abolition of animal exploitation, particularly regarding our diet. Indeed the production of animal products, always growing, implies suffering that the majority of the population is not known because of the opacity that must lobbies of the food or denies the immorality of denying this morbid production. The author, in addition to describing relevance with the reality of the industry of death, refutes every argument claimed that a vegan can hear daily on its way to conceive our relationship to animals, so much that after reading of the work it appears totally unlikely to continue to consume animal products in such indifference. The epilogue shows clearly, making it very clever parallel with the fight against human slavery, that this fight for the abolition of human dominion over the animal is not in vain and unexpected.
