One big factor of a Polar Reversal is the effect on our technology.
GPS will be useless, so will satnav.
The other big factor is that scientists know that as the poles reverse the earths magnetic field weakens, this causes issues with the radiation, and
nasties that the magnetic field protects us from.
oh yeah, and the good old compass will be useless, M6 south, becomes M6 North, London will be north of Birmingham, and Manchester will be in the south
I would also imagine birds and other animals that use magnetic field to navigate will be very confused.
