Not to sound (too) heartless, but who, besides Researchers is affected in any way if the White Rino goes extinct?
One day, our own species will also draw the drapes.
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.
