There appears to be two types of people in this thread.
Those who think we should pre-emptively come up with a solution and stop the damage before it gets out of control.
or
Those who think we should keep fucking shit up while having faith that in the face of annihilation some scientist will come up with a solution out of necessity to save everyone.
I know what the sensible solution is, but the second option definitely creates better drama. It would make for some great entertainment for the aliens watching us so they can be like "that was a great season finale of the human show, but unfortunately they canceled themselves so we'll have to watch something else now."
