Environmental degradation is a fact of life; so is species moving into the extinct list.
But once in a while, against the flow, few previously though-to-be extinct species turns out to survivors; albeit in small numbers. recently two such magnificient creatures moved back from the extinct list to the endangered list
Angola's Giant Sable Antelope
Arkansas Ivory-Billed Woodpecker
These two incidents are a joyful occasion; but it should not turn us away from the challenges of eco-conservation. Just imagine that we are being given a second chance to do better; there may not be a third chance!
