>are all for naught when that asteroid hits.

Hiding in space from an asteroid strike is a bad plan. Earth during an impact winter is still much much more habitable than anywhere else in the solar system.

I think you are approaching the problem the wrong way. If we are in space we can prevent the strike entirely.

Good point.

"unprecedented"

...actually precedented by all the resources we pour into forcing the climate TO change.

And, asteroid, seriously? This is the best we can do now? May as well not eat meals anymore because hey I could get hit by a bus on the way to work.
