Consecutive lunar cries that can alter the topagraphy of a planet would literally destroy the planet. Earth (or Gaia, or whatever its called) would probably be something like Mars.

Therefore, worlds of FFVII and FFVIII are completely different.
It depends on how many humans such a maneuver would destroy. Recall the utter destruction that occurred when Kefka moved the statues around in FFVI; the entire world map was changed. Some humans did survive; it's a mystery how many, due to the small scale of the game world, but there's apparently enough to build a future off of. Even if the human race got busted back to only a few hundred million survivors, the birth rate over the last 250 years seems encouraging:

Judging from that, humanity should be able to not only have its act well in hand after 4000 years, but actually have advanced noticeably beyond the stage at which the disaster occurred. However, as the Lunar Cry did not alter the world map in any perceptible way when it occurred in FFVIII, their sheer infrequency goes against FE's theory...that and basically everything else in the entire game.

You can also take a look at this U.N. population report showing similar figures:
