If a butterfly flaps it’s wings in China, so the old saying goes, a hurricane in Britain will not be far behind. The point, of course, is that even though we may not be able to see it, everything is connected and just like an inflated balloon, you can’t push it in here without something popping out over there. Well, thanks to a conflation of modern technology and the ancient forces of nature, we now have another example to use. If a volcano erupts in Iceland, people will be sleeping in airports all over the world. Count on it.
