The ethical treatment of animals has become an issue of serious moral concern. Many people are challenging long-held assumptions about animals and raising questions about their status and their treatment. What is the relationship between human and animals? Do animals have moral standing? Do we have direct or indirect duties to animals? Does human benefit always outweigh animal suffering? The use of animals for experimentation raises all of these questions in a particularly insistent way. Donna Yarri offers an overview of the current state of the discussion, and presents an argument, grounded in Christian theology, for significantly restricted animal experimentation.
