Since its original publication in 1975, this groundbreaking work has awakened millions of concerned men and women to the shocking abuse of animals everywhere — inspiring a worldwide movement to eliminate much of the cruel and unnecessary laboratory animal experimentation of years past.

In this newly revised and expanded edition, author Peter Singer exposes the chilling realities of today's "factory farms" and product-testing procedures — offering sound, humane solutions 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, Animal Liberation is essential reading for the supporter and the skeptic alike.
