Human Colonization / Living where we don’t belong

There is nothing like a string of subzero days and nights to awaken the mind to hard core truth. Humans are still tropical animals, molded by evolution for life within a consistent and moderate temperature range under sunny nourishing skies, equipped for a life shaped by ease and plenty. A perpetual cheese and wine party punctuated by afternoon naps, walks on the sea shore, craft time, oodles of festivals and rituals. Naked fun! Art! Music! Jewelry!

We draw smoothly curving lines of human dispersal ‘out of Africa,’ as if any wandering group of humans that strayed far enough north to encounter snow, iced-over rivers and lakes, long periods of darkness, and death by freezing, looked upon the land and unanimously declared: “We like this! Let’s stick around.” Every one of them would have promptly died of hypothermia or starvation. Homo erectus apparently ran up against a climate barrier and kept to a southern arc across Asia and into the SE Asian Archipelago and Southern Europe, except for a few Neanderthals who moved beyond southern Europe and the Middle East and into colder areas, at least seasonally or during interludes of warming climate.

Information about archaic Homo is changing rapidly, so this is a generalized map.

Humans who wanted to migrate into hostile country had to be prepared first; had to have control of fire and rudimentary technology(Thousands of migrants in the 1800s died when trying to cross the western deserts and mountain ranges of the United States because they were totally unprepared and ignorant of the endurance the trip would demand.) There had to have been much seasonal migration on the part of archaic humans to northern lands, with returns, both temporary and permanent, to warm climates, before settlement outside the evolutionary comfort zone could take place. Let’s face it; without fire, food acquisition and preservation, tools and warm clothing, humans could not have broken the climate barrier.

Modern humans face the same situation. Our bodies have only superficially adapted to life outside the tropics. Colonization of cold mountain climates (and desert, and arid plains) has only been possible by means of technology. Fire, clothing and food preservation may seem primitive to us, but the refrigerator in my kitchen keeps food from freezing as well as rotting, and the heater that sits in my living room is little more than a campfire fueled by natural gas. Despite adopting a cocoon of parka, hat, gloves and insulated boots, I’m like an astronaut leaving his or her spacecraft to enter utterly hostile conditions when I leave my house.

The steep (and untenable) rise in world population is the product of fossil fuels.

I began thinking about this yesterday when I looked out a kitchen window and saw a tiny woodpecker banging away at one of the trees. It looked so vulnerable and lost – as if it should have migrated south with most other birds that summer here. But then I realized, it’s ‘out there’ in sub zero weather and I’m essentially stuck in my artificial environment, in my life support system. And I thought of the deer, pronghorn, elk and moose, of the wild horses scraping the snow for dried grass, of the intense stinging cold that comes at night, which would freeze a human solid as a rock if he or she made a simple mistake and could not get back to ‘civilization’ – which in Wyoming isn’t much, but our human outposts provide what is necessary: warmth and food.

The bad news is that humans today exist in artificial, depleted, or hostile environments, and exist on the chain of energy and products, including medicine, food and clean water, heating and air conditioning, and transportation, that is derived from fossil fuels. The worst news is that overpopulation in developing nations, which mostly are located in the tropics, has been made possible by the fossil fuel energy explosion. Tropical environments are poor food producers and “naturally limit” human numbers.

While arguments about climate change go nowhere, we can see that the discussion has become irrelevant. Our fossil fuel technology has built a house of cards that a mere puff of chance will topple.

  1. Oh yes. And topple it will. Any person willing to acknowledge hard facts should be able to see that. But I hear sooooo many people trying to convince me that humans are in it for the long run. Sorry people, before the oil is gone humans are going to die in gigantic numbers because of fights for resources and old and new diseases. I dearly hope that my children have no children of their own.

    • I try to point out that there are actual causes for how humans behave (not supernatural entities pushing us around) just as there are causes for everything else. I’m hoping Asperger people will “get” that our behavior makes sense and is valid and ought to be valued. Americans are in denial and believe that nothing can happen to “us” – we’re God’s spoiled children.
