This book presents an ethical discussion of the possible future Universal Declarations of (diverse specific nonhuman) Animal Rights. It contributes to a basis for a discussion about (nonhuman) animal rights concerning diverse aspects and quality of (nonhuman) animal life. Doris Schneeberger deals with the interpretation and justification of animal rights, and argues that because (nonhuman) animals are individuals whose lives are intrinsically and inherently valuable, their goods and welfare ought to be protected. She claims that these rights should be protected in possible morally advanced societies of the future.
