Animal Liberation Now includes alternatives to what has become a profound environmental and social as well as moral issue. Widely recognized as the foundational text within the animal liberation movement, Peter Singer's Animal Liberation opened my eyes to the radical philosophy that all animals are worthy of equal consideration. In the fifty years since, science has further vindicated Peter Singer's arguments about animal sentience, vegetarianism has become widespread, and the book has helped change the minds of millions.Animal Liberation Now is written with the honesty and philosophical depth characteristic of all of Singer's work' J. He is professor of bioethics at Princeton University and has published numerous books, including The Life You Can Save (2009) , The Most Good You Can Do (2015) and Ethics in the Real World (2016).

The book has also received a wide range of philosophical challenges to his formulation of animal rights. Activist Ingrid Newkirk wrote of Animal Liberation, "It forever changed the conversation about our treatment of animals. Few books maintain their relevance – and have remained continuously in print – nearly 50 years after they were first published. Other activists who claim that their attitudes to animals changed after reading the book include Peter Tatchell [7] and Matt Ball.

It also discusses the toll that meat consumption is taking on the environment and the profound risk factory farms pose for spreading new viruses potentially even worse than the one that causes COVID-19. In particular, he argues that while animals show lower intelligence than the average human, many severely intellectually challenged humans show equally diminished, if not lower, mental capacity and that some animals have displayed signs of intelligence (for example, primates learning elements of American sign language and other symbolic languages) sometimes on a par with that of human children. This led Singer to inquire as to why and then to read Ruth Harrison's book, Animal Machines, as well as a paper by Roslind Godlovitch (who would later co-edit Animals, Men and Morals), which convinced him to become a vegetarian and to take animal suffering seriously as a philosophical issue. He argues that animals' rights should be based on their capacity to feel pain more than on their intelligence.

In 1975, Animal Liberation started a worldwide movement when it revealed the abuse of animals in factory farms and laboratories.The moral philosopher Roger Scruton criticised Singer's works, including Animal Liberation, saying that they "contain little or no philosophical argument. An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike.
