This is a subject that I've pondered since I was 16yrs old when I went through a deeply spiritual time in my life where I received many clairvoyant type messages, or visions about End times scenarios and a pole shift was indicated as the source for the cataclysms that would precipitate the cleansing. I feel it on an instinctual level, as well as deductive thinking after adding up all the indications that something is going on. It's happened in fairly regular intervals throughout Earths history and when you ad the apparent influence of both a large planetary object moving through the solar system, coupled with the fact we're about to cross the galactic plane there's a very good chance the magnetic effects will shift the poles. Knocking us back to the stone age, once again.
This video series presents a good argument for the pole shift theory:

The messages I received when I was 16 was that the Earth needs to heal from humanity's negativity and the environmental destruction. Basically we got it all wrong and ended up poisoning our spirits, as well as the planet to the point where the path is unsustainable and we've already passed the tipping point. It's Gaia's time to heal now...
