a) blowing up aka exploding the planet is FAAAR different than wiping out "every living-thing"
b) we could kill all the animals in the sea, even at the depths we cannot even reach? i think not. there are plenty of insects that are resistant to radiation that also live underground, not to mention plants. you are just fucking stupid.
think about this, who the hell would nuke various countries like several in africa that completely lack any metal based technology? just because we could kill everyone doesnt mean we will.
meade, go drown yourself in your own stupidity.
