puzzled

When i'm taken for my annual universal tour
on the lap of the earth in its axis
I see the third world becoming the first
and the first becoming the third
and now i know how the first becomes the last
and the last, first,
north becomes the south
and south becomes the north
and i know geography is a human ploy
colour is in the mind
not in the skin

the Homo sapiens....scattered thickly all around
just one species ?!
