So, as I understand it, a long time ago, way back, as humankind emerged from their hunter/gatherer roots, civilization developed in the Fertile Crescent (it being a place particularly conducive to plant and animal domestication) while much of the rest of the world,( save China and a bit later Mesoamerica), remained tribal people for millennia.
Before too long these newly sedentary farmers created complex societies that produced artisan craftsman and a written language. Unfortunately for those urbanizing folks they didn’t have a good grasp on the importance of environmental stewardship: deforestation and soil degradation took its toll. The civilizations of the Fertile Crescent fell into decline.
But, over the millennia, technologies developed by these folks traveled with relative ease and speed into soil rich Western Europe, where, before long, (relatively speaking), the Spanish, Portuguese, French, English and Dutch became the powers that dominated and exploited the rest of the world.
And so, it’s pretty clear geography and circumstance is responsible to a considerable extent for the historical dominance of the Western Europeans. One would think such knowledge would undermine the racist tendencies of our primitive minds. I fear that’s not the case.
