Remember that the only thing that protects us from the merciless radiation of the Sun is the magnetic field around Earth, which is theoretically caused by the constant revolutions of molten iron. Interestingly enough due to our slightly elliptical shape, the most protection garnered from this field, is at our equator, the center of the 3rd world. Perhaps one day we will be crossing the border South instead of North for survival, and I'm sure someone will come up with an excuse to take our land again.
