Moon break-up = uninhabitable Earth. WHY? (I'm not science geek)
Why can't the Earth survive without the moon?
I'm just a kid.
in this movie, earth is survived, some things only changed

the earth will survive fine
our society...not so much
it stabilizes the wobbble of the axial tilt and keeps the Earth from rotating to quickly
There are documentaries posted on YouTube describing what happens if the moon disappeared. Everything on earth would change dramatically, and not in a good way.
shareOur planet experiences seasons (summer, winter, autumn and spring) because of the tilt of the axis of our planet. The tilt is at 23.4 degrees currently. The reason we have that stable tilt is because of the gravity of the moon. Our planet is not completely stable though, we fluctuate very slowly between 22.1-24.5 degrees on a 41000 year period. So in 41000 years our tilt will be 23.4 degrees again. If we lost our moon we'd wobble around with an everchanging tilt between 0-85 degrees. That would mean we'd go from summer to winter and back again VERY rapidly. Those summers would be hotter than any summers you've experienced and the winters colder. Very few species could survive this and we certainly couldn't, only the simplest of lifeforms would stand a chance. Maybe some bacteria and simple life forms in deep water caves or whatever. We'd also have shorter days, stronger winds, higher tidal waves and so on. Basically extreme weather.
There would be no way for humans to survive to evolve at all like they did in this movie so they were overly optimistic about the results of the moon breaking up. Though the moon breaking up is not the same as the moon disappearing since there's still a clump of mass there and that mass has gravity, it's just not as concentrated, but I'm sure it would still have SEVERE consequences.
Not ever I did read so much *beep* in one place...

Without the Moon, the Earth woul not "wooble" much more than it do today... mars has no big moon and is just fine Not-Wobbling much...
He's pretty accurate in his answer. The Earth and Moon orbit around a shared center, which is not at the center of the Earth. Our orbit is called a double planet orbit (which looks like a wobble) based on the total mass of both the Earth and Moon. The destruction of the Moon would definitely change this, depending on how much of the it remained or if it was completely destroyed. Theoretically, over a long period of time, even Earths orbit around the sun would change. It is as important as the Earths magnetic field is making Earth a viable place for life, intelligent life, not to mention civilization. (Civilization depends upon agriculture, which is plant life, and predictable seasons and weather patterns.) The Moon matters, a lot.
It's why scientists are always upping the improbability of finding life, intelligent life, and alien civilizations elsewhere in the universe, because of all the outcomes of so many events that must fall into place. It really is a sort of magical thinking in believing humanity is one of many intelligent species in the universe. Humanity is very likely, and probably, the only intelligent species capable of creating advanced civilizations. We've done it in the past, and will continue on doing it, for a very long time. It's would be a religious-level miracle to discover another intelligent life-form like us, on a world capable of sustaining an advanced civilizations.
Another thing is season really help having moving evolution along. Without having the moon, Earth's rotation could be as short a 12-hour days (making for some VERY high winds. Life could've been possible in this scenario, but not humans as we are today). Place like the Mayans would be summer for one point in time, but then freeze into the arctic for another.
Crazy stuff indeed!
On the positive side, no more werewolves! I mean, they're only supposed to change during a full moon so now, no problem, they never change into werewolf form! ;-)
(Yes, this is a silly post.)
Sig, you want a sig, here's a SIG-sauer!
Basically the part of the moon fell on earth. The impact is probably something simillar to an insane ammount of nuclear bombs,
