I need to know if we will be wiped out like the dinosaurs?

Yeah I need to know if we will be wiped out like the dinosaurs? Seems to me, it's not a question of if it happens, but when. Will we have colonised other places by then, or would that be it? Hadn't we better get a move on? I mean they cut the space budget, there's no contingency to prepare for hemorrhoids invading the earthbound skies so what hope is there left then for us all.. then?
