Nope. We can get by if we have access to in depth scientific knowledge or if we don't exclude all sources of animal protien by eating eggs and dairy. Purely vegitarian diets will eventually kill you without suppliments. No he was clearly saying "it's still morally permissable to eat them." Enjoying it is just icing on the cake and a sign from our bodies about how important meat is to our diet and has been for a very long time. Oh, the irony. but the vast majority of us are not in that situation. All things die. But making their lives hell while they live is wrong. In particular, herbavors are dependent on their carnivors to keep their populations in check. For domestic animals, that carnivor is us. Destroy that relationship and they will suffer greatly. So I take it you avocate giving animals the vote? It isn't needless. It is necessary.
