interesting idea, i suppose that eventually, radiation from godzilla could make much of the planet uninhabitable, and could potentially kill off most humans. of course godzilla can be a bit slow, so by the time that would happen, i figure the humans that still survive, would have found efficient ways to sheild themselves. now the issue would be surviving all the giant monsters around. also, what if australia became monster island, or actually a monster continent? it would be an even more epic place! also its definetly big enough! just a fun thought.
