 Animal ethics is a burgeoning field in ethics. The most famous work in the area is, of course, that done by utilitarian Peter Singer, who argued that the best consequences will be brought about if we become vegetarians, thereby ending the terrible suffering endured by animals raised for food. Following in Singer’s footsteps, much of animal ethics is concerned with issues surrounding the use of animals for food, scientific research, and entertainment purposes, legal issues addressing overt cruelty to animals, and how to deal with rapidly increasing populations of both domestic and wild animals.
