Poles Interchange

Are you talking about the magnetic poles? or an actualy physical reversal of north and south geographicly? Magnetic poles do reverse themselves from time to time, it happens very slowly over thousands of years and no harm has come to the earth from it. As for an actualy physical reversal of the physical north and south poles....lol...well, it's impossible, it cannot and will not happen, so don't worry, it isn't going to happen, 2012 was a movie and a myth. As for yellowstone being prohibited,I'm not sure what you mean. Tens of thousands of people visit yellowstone national park every year, it isn't "prohibited", it's still open.

The shift of poles actually cause severe changes in the climatic conditions of the earth.The land mass will get sunken in water if fast changes would take place.So also high magnitude earthquakes and Tsunamis will rock various parts of earth.I feel you should not be a hangover of the movie 2012.Nothing of that sort is yet confirmed by our geologists.So whatever the case maybe just enjoy the time you are here on the earth.
