Morton 105: "[I]f 'the whole is greater than the sum of its parts' is true, it doesn't really matter if those parts get replaced. We'll still have our lovable old whole intact. Say the whole is the biosphere and say the part, which we very much imagine as a component because of the holism, is a polar bear. Never mind. They will go extinct and another lifeform will simply have to evolve to take their place. This kind of thought might not be so good for ecological ethics"
