2012 is suppose to be the start of another pole shift in the earth,its not the end of the world but this will change for everyone with the weather and all im sure some places will become inhabitable but this will take many years.
yeah the mayan indians thought 2012 was the end of the world.they based thier crops and time on the stars and were able to predict seasons and so on based on the stars and they were only able to go as far as 2012 so they assumed the world would end. you can google pole shift in the earth or the reversal of the magnetic field there are some pretty cool theories out there.but thats all they are ,no one will know the end of the world or the return of christ. but we can look around and see the earth is changing.
