I thought I'd discuss another topic. Have you ever stopped to consider how much of the continent, and even much of the world, is doing things all wrong? What I mean is....the human body isn't meant to handle extremely low temperatures. We don't have fur like wolves or rabbits, we get sick or die if the temperature is too cold, experience massive dryness internally and with our skin if the temperature is too cold, fire is actually nature's way of clearing out forests for new growth and, except for man, not one creature on the planet sticks around when a fire starts (AKA--It just isn't something we were naturally meant to start on purpose), nothing grows when it drops below freezing so, therefore, food is basically non-existent unless you stored a bunch of nuts for the winter like squirrels or know how to find roots like rabbits, and due to our slower speed, non-ferocious jaws, lack of claws, etc. we technically weren't "meant" to be predators for meat or to catch animals in order to get their fur. Sure, we "have" adapted, but did we need to?
Perhaps nature was giving us clues all along to what we should do, but we were ignoring it. We should have been watching the sky and seeing where the birds were heading in the Fall/Winter, and also realizing the fact that the only potential food we could easily catch "without" spears or other artifically created things, which are bugs believe it or not, are also without a trace in the winter months. IMO, I think man was meant to travel South when a hint of cold comes due to all of the clues that tell us we weren't meant to survive there. Prior to automobiles and such, walking may not have been out of the question. Say, for example, you wanted to walk from Decatur, Illinois to Cape Coral, Florida. The trip is 1,180 miles. Say you walked 5 hours a day, eating food along the way that you found in orchards and fields and such. An average human walks 4 miles per hour. At 5 hours a day that means each day you'd walk 20 miles each day. 1,180 divided by 20 miles is 59 days. Let's just make it 60. If you left right to the prior onset of Fall in Illinois when it was getting colder, you'd be down in Cape Coral (I just used this as an example--no particular reason) after 2 months and it'd still be nice and toasty warm down there. In return, you'd have months of typical Florida winter crops, such as strawberries, oranges, and such..much of our crops here grow in the winter believe it or not.
So, when you think about it....how our bodies can't seem to handle extreme temperatures, there's no natural food up there in the winter, etc., etc., etc., perhaps we were meant to walk down South when it got too cold up there, and walk back up there when it got way too hot down here. Perhaps we were all meant to be drifters, moving from one place to another in order to protect ourselves from the elements and go to places that have growing food. In addition, wouldn't that be nature's way of giving us a variety throughout the year? Central crops in the Summer and Tropical crops in the winter? Although the drifters of today don't seem to do things normally and, instead, pan-handle for money to buy their food instead of try searching for it themselves, perhaps, at least concerning the traveling part, they're onto something we just haven't figured out for ourselves yet. It's just something to think about.
