In order to provide a human being with a slight advantage, it is morally acceptable to cause an animal considerable suffering. But this is a moral mistake. To the extent that other animals have interests, their interests deserve to be taken as seriously as the corresponding interest of human beings. And it is an obvious fact that many higher animals do have interests. All animals capable of feeling pleasure and pain have interests. It is in their interest not to suffer, and it is in their interest to experience pleasure. Other animals are not different from human beings in this respect. How do we know this?
