Collection of essays I picked up in college during an environmental ethics course.I have generally found essays somewhat dry but this book is fascinating in it's arguments.For example, the section on the differences between humans and animals yields this:"How could anyone seriously believe that animals do not feel pain?After all, we have virtually the same evidence for animal pain that we have for human pain......So, on what grounds could anyone possible say animals are insensitive to pain?"Some areas are graphic but author makes very persuasive arguments on several topics.
