Has our society become too complex to sustain?By George Monbiot, published in the Guardian 19th April 2010Man proposes; nature disposes. We are seldom more vulnerable than when we feel insulated.The miracle of modern flight protected us from gravity, atmosphere, culture, geography. It made everywhere feel local, interchangeable. Nature interjects, and we encounter – tragically for many – the reality of thousands of miles of separation. We discover that we have not escaped from the physical world after all.Complex, connected societies are more resilient than simple ones – up to a point. During the east African droughts of the early 1990s, I saw at first hand what anthropologists and economists have long predicted: those people who had the fewest trading partners were hit hardest. Connectivity provided people with insurance: the wider the geographical area they could draw food from, the less they were hurt by a regional famine.But beyond a certain level, connectivity becomes a hazard. The longer and more complex the lines of communication and the more dependent we become on production and business elsewhere, the greater the potential for disruption. This is one of the lessons of the banking crisis. Impoverished mortagage defaulters in the United States – the butterfly’s wing over the Atlantic – almost broke the global economy. If the Eyjafjallajoekull volcano – by no means a monster – keeps retching it could, in these fragile times, produce the same effect.
