"[I]t is clear you have either never taken a course in ecology and evolution, or forgot the message. There is this strange thing called a food web – in which organisms are primary producers, eat primary producers, eat the eaters of primary producers – and so on. That is called life. It has NO ethical or moral values. Those are HUMAN values. A wolf or lion kills another animal – the pain and suffering are not ecological issues – the life of the wolf or lion is the issue. If the wolf or lion dies of starvation – then the prey potentially become over populated – like the deer in Princeton. Your values are not the values of nature."
