What significance does the South Pole serve?

Question

10 points will be given!!!

Answer 1

The North and South Pole serve our compasses, because if we didn't have North and South poles, then the planes and the compasses won't point true north and that could be a huge problem to magnetosphere and the entire earth. We would be turning so fast that we couldn't walk one step ahead.

Answer 2

None, except what we attach to it.  It is the one point on Earth where all directions are North, and it is also the coldest point on the planet.  The Earth rotates about the axis formed by the North and South poles, but, then, that's the definition of the poles, not their significance.
