Two words: Killer Asteroids

Posted by Rofang on 12-31-2007 in Are humans the most valuable organisms on the planet?

I'm not fond of what the human race has done and will continue to do to the planet - namely, poisoning it and striking massive blows to biodiversity. And yet I would still argue we are incredibly valuable, for the sole reason that no other species has the capacity to save the planet from the next giant asteroid impact.
