You'd think that it would be hard not to notice a giraffe, right?
They're not known for being terribly loud animals, but they're certainly tall enough. And a curious one would certainly demand our attention if it bowed down and got in our faces.
Yet, the same apparently can't be said for them as a species because they somehow made it onto the endangered species left without any widespread concern.
And we don't want to be in a position where we only notice that they're missing.
