?Peter Singer may be the most controversial philosopher alive; he is certainly among the most influential.??The New Yorker

?A most important book that will change the way many of us look at animals?and, ultimately, at ourselves.??Chicago Tribune

Updated for the first time in nearly 50 years, this mainstay of the animal rights movement includes the most recent information about humanity's relationship to animals, including the explosion of factory farming worldwide, and why our cruelty towards them persists.

One of the most influential books of the past half century, Peter Singer's Animal Liberation has only grown in relevance and popularity since its original publication in 1975. Named one of Time magazine's ?All-Time 100 Best Nonfiction Books,? this groundbreaking work has awakened millions to ?speciesism??humans' systematic disregard of nonhuman animals. Singer inspired a worldwide movement, transforming our careless attitude toward animals and helping to reduce and hopefully eliminate the cruelty we inflict on them. In Animal Liberation, Singer exposes the chilling realities of today's factory farms and product-testing procedures, destroying the spurious justifications behind them and exposing just how woefully we have been misled.

Now, in this updated edition?revised from top to bottom?Singer brings us to the current moment, covering important reforms in the European Union and individual U.S. states. But he shows us how these measures are offset by the explosion of factory farming caused by unprecedented demand for animal products in China. Singer also explores how meat consumption is negatively impacting the earth, and reveals how factory farms pose a profound risk for spreading new viruses worse than Covid-19. In addition, Singer offers alternatives we can use to address this profound environmental, social, and moral issue.
