In Putting Humans First: Why We Are Nature's Favorite, Tibor Machan argues against moral perspectives that require taking animals' interests seriously. He attempts to defend the status quo regarding routine, harmful uses of animals for food, fashion and experimentation. Graham and Nobis argue that Machan's work fails to resist pro-animal moral conclusions that are supported by a wide range of contemporary ethical arguments.
