Henry Spira's extraordinary life as an activist shows that an individual can make a difference. Inspired by the thinking of Peter Singer in the early 1970's, Henry turned Singer's ethical lessons into action, launching campaigns against organizations whose practices caused unnecessary suffering to animals. By thinking about how giant corporations, including Revlon, Avon, Perdue, and McDonald's, might be vulnerable, he found ways to change their practices and save the lives and health of animals all over the United States. This book tells the inspiring story of a lifelong activist whose creativity and careful thought set the standard for the animal rights movement in the twentieth century.
