I recall Bugenhagen saying that the planet will only destroy what it thinks it must, when Holy was summoned. If the planet wants the human race to survive, then it'll let it survive. If the planet felt that the humans were too destructable, then the planet will get rid of them. Apparently, not all of the human race was meant to be destroyed, hence Cloud and others still being alive for Advent Children.

I realize that was just a minor typo, but it's funny, 'cause it sounds like you're saying that they saved the planet from Linkin Park .
