Humanity Almost Vanished 70,000 Years Ago, and Can Again


A number of studies described in a recent NPR article agree that slightly over 70,000 years ago, after a supervolcano eruption much larger than any we’ve seen in recorded history, total human numbers were reduced to a few thousand or less.  Now we find ourselves in a heavily overpopulated situation where we may surpass the Earth’s capacity to provide food and energy within the next few decades, and we need to think ahead as to how to survive the coming period of extreme volatility.  Still, there are supervolcanos in the world that are centuries and millennia past their normal eruption cycle, just ready to blow.  Surely we are smart enough as a species to think ahead and prepare for such calamities, aren’t we? 

I leave this as an open question.  It has meaning well beyond the immediate topic.  Thanks for reading – Tim
