Well, ignoring natural disasters such as asteroid impacts, local supernova event or some such, I do worry there's going to be a lot of conflict for a dwindling set of resources if we're not careful as a species - i.e. more of a whimper than a bang.
Of course, if it does turn out to be a major asteroid impact or the like, then more of a bang than a whimper.
Try to be reasonable... its easier than you think...
