One of the things that is so difficult to get over to the "Arrrgh! We're running out of everything!" crowd is that we humans actually create resources by inventing the technology that does that creation. I've blathered about this with respect to minerals here often enough. Today's example is fresh water. Of course, we all know that there's a water cycle, that we don't destroy water by using it, we just dirty it. But it is true that there are areas of the world that are becoming short of potable water.
