Now fully rewritten and entirely updated to reflect the pressing problems of today, Animal Liberation Now presents the definitive case for radically rethinking humanity's relationship with other animals 'Probably the single most influential document in the history of ... animal welfare' Guardian 'Raises ethical questions that every human being should take to heart' Yuval Noah Harari In 1975, Animal Liberation started a worldwide movement when it revealed the abuse of animals in factory farms and laboratories. In the fifty years since, science has further vindicated Peter Singer's arguments about animal sentience, and the book has helped change the minds of millions. But the situation for animals has in many ways grown worse. This revised edition, of which about two-thirds is entirely new, documents these and other developments, such as the impact of meat consumption on climate and the spread of dangerous new viruses. It refines its arguments in light of new evidence, equips the reader with fresh tools and advice, and shows us all the road ahead. 'Animal Liberation Now will motivate a new generation of readers who are resolutely committed to creating a just society for all' Joaquin Phoenix 'The indispensable foundational text for the movement, new and updated' J. M. Coetzee 'If I have to pick the book that had the most impact on me, I would say Peter Singer's Animal Liberation' Jane Goodall 'One the most important books of the last 100 years' Ecologist
