I often wonder if there is any argument to be made that completely eradicating the Guinea Worm, Anopheles mosquitoes, Variola major and Variola minor (SmallPox Virus) is not a 100% good objective.<p>My perspective (as well, I'm guessing, approximately 100% of humanity's, to quite a few significant digits), is that any significantly lower being that hurts humanity, or presents a threat, has no right to exist, and therefore we'll terminate its entire existence.<p>But, you can see, taken to its logical conclusion, that thought pattern could lead to less than desirable ethical behaviors.<p>Perhaps we draw the ethical line at the vertebrates. And maybe Octopuses.
