Few books maintain their relevance – and have remained continuously in print – nearly 50 years after they were first published. Animal Liberation, one of TIME’s “All-TIME 100 Best Non-Fiction Books” is one such book. Since its original publication in 1975, this groundbreaking work has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. In Animal Liberation Now, Singer exposes the chilling realities of today's "factory farms" and product-testing procedures, destroying the spurious justifications behind them and showing us just how woefully we have been misled.

Now, for the first time since its original publication, Singer returns to the major arguments and examples and brings us to the current moment. This edition, revised from top to bottom, covers important reforms in the European Union, and now in various U.S. states, but on the flip side, Singer shows us the impact of the huge expansion of factory farming due to the exploding demand for animal products in China. Further, meat consumption is taking a toll on the environment, and factory farms pose a profound risk for spreading new viruses even worse than COVID-19.

Animal Liberation Now includes alternatives to what has become a profound environmental and social as well as moral issue. An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike.
