The entire country would be affected if White "Rinos" went extinct. And, may I add, for the better. (you did spell it "Rino") :)
But seriously, since it wouldn't be a "natural" extinction, but rather the result of human activities, I can see how it might upset some people.
Lol! I didn’t even catch that freudian slip; RINO vs Rhino.
You can tell what was on my mind.
As to the American White Rino, maybe that species could be confined to mating in its already-limited gene pool in DC-fertility would decline, and as long as no one imported any Rino subspecies of any type for mating, that species might become extinct-and it’s a good thing...
