What, if any, kinds of actions done to try to improve the treatment of animals (including, perhaps, trying to eliminate various uses of animals) are morally permissible? Which, if any, are morally obligatory? Changing our diets? Educating others? Working for larger cages and more humane treatment, or for the abolishment of (some) animal use industries, or both? Trying to change the laws to better protect animals? Illegal actions (done covertly or openly)? Undercover investigations to reveal animal abuse? Rescuing or releasing animals from animal use industries? Exposing people and businesses who support harmful animal use? Violence of any kind, ever? Threats of violence? Terrorism? We will explore a range of tactics and attempt to evaluate them morally.
