This is from the plot summary of the Najica Blitz Tactics Manga:
Erm. We’re currently at about 75% of the Earth’s surface underwater. If that went down to 17%, well… I don’t think it could. All that water would have to be someplace.

17%? What the heck were they trying to say, anyway?

Maybe it was saying that 17% was the only remaining land on the surface. Like, they were saying that 83% of the earth is now completely covered in water. Just a thought.
