No, you are incorrect. Human civilization started in west Asia, today's Turkey and Syria aka the Near East..<quoted text>
I'm afraid you are right, caveman. Human civilization is ultimately based on africulture, no matter how technologically advanced we become. The environment has to be good enough for the earth to be able to produce the food. If it can't, then a lot of people starve and civilization collapses.
It happened to the Anasazi, probably to the Mississippians, and to some civilizations in Central Asia about the same time. In those days, with far far fewer people, the survivors just fanned out and became hunters, herders, and scattered subsistence farmers. Now there are far too many people to do that. When the climate deteriorates to the point that crops fail on a global scale, billions of people will starve.
Your examples of climate change are too recent because Central Asia went through catastrophic changes much much earlier. We are just beginning to uncover the buried history that the Soviets occupied until their recent demise.
