It will not be a hunter practicing fair chase that finally kills the last lion, elephant or rhinoceros.
It will be an impoverished villager who kills a whole pride when he laces one of the carcasses of his cattle with virulent herbicide. Or by poachers and their buyers with an insatiable greed for ivory or rhino horn or whatever.
But most probably, will quietly disappear forever in the face of inexorable further encroachment into their habitats by an apparently unstoppable tsunami of humanity.
Humanity with their insatiable need and unsustainable greed.
G. Chislett, Sidney
