But are not humans also animals? It would be strange to claim that an animal life is more valuable than a human life, no? Should we intervene when a Pidgeon eats a worm? What about a Kalahari Bushman who hunts deer, should that also be prevented? Where does this principle of 'preventing suffering' begin and end. I think we should reduce suffering as much as possible, but surely to eradicate it entirely would be unwise?
