Judgement day defense strageity.

welcome to the modern age we have guns rifles heavy machine guns and tanks and a whole nuclear arsenal. we also have have rockets and are working on space ships if the world was going to end some time in the future we would have already gone and left.

We're just a wart on the ass of the world. The Dynosaurs have been around for at least 100 millions of years. Something that can be remotely called human is only around for about two millions if that.

Considering all you mentioned above, chances are we blow ourselves up before we manage to build an interstellar space ship. And the world would shrugg us off and continue without us.
