&gt;Creatures should go extinct.<p>We&#x27;re currently in the midst of a mass extinction which is largely being driven by humanity. The selection pressure that we are placing on many species for outweigh&#x27;s natural selection&#x27;s ability to act on random mutation to promote fitter variants.<p>What you are promoting isn&#x27;t a course of action that will lead to an alternative, rich ecosystem better suited to current conditions. It would simply lead to an impoverished and more fragile ecosystem, ultimately less capable of supporting humanity, if we want to go down the reductionist utilitarian road.<p>We are custodians of an astonishingly rich and diverse biosphere, which we are already damaging. We have a duty to try and mitigate that damage.
