Ever since I spent 3 months on student exchange in Australia in 1992 and realised that I was not walking upside down, let alone falling off the earth, I have been very adamant against the use of “up” or “down” when describing locations on this planet. Without a reference point in space, there is no “up” or “down”.
Try to think of the world map as follows, for once:
Only too bad that even the publishers of this map cannot refrain from using the words “upside down”.
But this is not the only way in which maps over-emphasise the Northern hemisphere.
