What we build today may have to sustain us for a century. The population explosion is expected to peak in the 2040’s, just 30 years away, and we can’t expect that time to be easy. Not only will out-of-control growth exceed the capacity of much of our infrastructure, but when the trend turns around with a declining population will come a declining tax base, and there may truly be no money for infrastructure repairs and improvement. For this reason, when we pursue an infrastructure update project today we should build it to serve us with minimum maintenance for a century, not just a few years. I can’t help but think of the Roman roads, some of which are still in use 2000 years after they were built. Can we think in those terms? Are we smart enough as a species to anticipate the future and prepare for scenarios that are likely but still decades away? Or are we closer to lemmings, insects, and bacteria than we think, such that we won’t be able to avoid growing explosively until our infrastructure fails and our numbers are reduced by mass starvation? It is up to us, but serious action is needed now, and I’m not sure we’ve set an encouraging track record so far. This is a badly needed bit of consciousness raising, but we need to be talking seriously about what will happen in the next century, for our children and grandchildren if not for ourselves.
