Humans, like cockroaches, are exceedingly easy to kill but very difficult to completely exterminate.

Then again, our technological civilization could be argued to be a part of our extended phenotype - just as one might regard an anthill as a part of the ant colony, rather than a part of the ground. If one takes that view, then to extinguish a culture is tantamount to an extinction event.
