One of the key modern writers on ethics, Peter Singer has more than anyone else defined the terrible gap in human understanding about our relationship with animals. Bringing together some of his key writings, Why Vegan? makes a devastating case against our blind failure to face up to what we do to other creatures and the ethical ruin this creates. Both inspirational and challenging, Singer's writings ask the most urgent questions about how we should lead our lives in the 21st century. GREAT IDEAS. Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted.

They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
