I have been to all these zones and nations and find this reasonably accurate. This map was created by one or more people with global consciousness, which was the goal mindset of my school, the Nizhoni School for Global Consciousness. I salute whoever made this map for living his or her or their life(s) in such a way that this could be created.
I do find it astonishing as I walk around the freezing streets of London (4 degrees C) that there are so many Africans, Arabs, and Indians here. The cold, wind and rain cannot be comfortable for them.
I think a global version of this should be created and presented to everyone when they get a passport so they get a sense of what they are leaving and what frying pan or freezing pan they are leaping into.
