You know that saying, "Don't cry because it's over, smile because it happened"? That has to be hard to take if you're an endangered species. I mean, nothing lasts forever, but when you're among the last of your kind, chances are you're not smiling because you were around.
There are even fewer reasons to smile this year, as 2018 saw the last of some wonderful creatures, and 2019 isn't looking much rosier.
