Ethics is a human invention, justifable only on the basis of collective human convenience.
The difference between human and animals is human convenience is heavily and inescapably influenced by the relatively strong and pertinent instinct for reciprocity amongst other humans. There is little sign of, and little pertinence to, any instinct for reciprocity amongst animals.
