The core concept that has to be grasped to make sense of the future looming up before us, it seems to me, is the concept of limits. Central to ecology, and indeed all the sciences, this concept has failed so far to find any wider place in the mindscape of industrial society. The recent real estate bubble is simply another example of our culture’s cult of limitlessness at work, as real estate investors insisted that housing prices were destined to keep on rising forever. Of course those claims proved to be dead wrong, as they always are, but the fact that they keep on being made – it’s been only a few years, after all, since the same rhetoric was disproven just as dramatically in the tech stock bubble of the late 1990s – shows just how allergic most modern people are to the idea that there’s an upper limit to anything.
It’s this same sort of thinking that drives the common belief that limits on industrial society’s access to energy can be overcome by technological innovations. This claim looks plausible at first glance, since the soaring curve of energy use that defines recent human history can be credited to technological innovations that allowed human societies to get at the huge reserves of fossil fuels stored inside the planet. The seemingly logical corollary is that we can just repeat the process, coming up with innovations that will give us ever increasing supplies of energy forever.
Most current notions about the future are based on some version of this belief. The problem, and it’s not a small one, is that the belief itself is based on a logical fallacy.
One way to see how this works – or, more precisely, doesn’t work – is to trace the same process in a setting less loaded with emotions and mythic narratives than the future of industrial society. Imagine for a moment, then, that we’re discussing an experiment involving microbes in a petri dish. The culture medium in the dish contains 5% of a simple sugar that the microbes can eat, and 95% of a more complex sugar they don’t have the right enzymes to metabolize. We put a drop of fluid containing microbes into the dish, close the lid, and watch. Over the next few days, a colony of microbes spreads through the culture medium, feeding on the simple sugar.
