One of the interesting things about sustainability science is that it is includes a lot of learning about how the rules of natural systems are changing. It treats natural systems as constantly creating new problems for us to unravel. It's a rather different expertise than most of the other sciences. A good example is the evidence that the complexity of the problems we're trying to solve are getting increasingly complex as if without bound. That points to an approach of insolvability if the pattern were to persist, which seems quite likely.
While requiring a lot of insight into how science works with rules that treat natural systems as deterministic processes, sustainability is really more about why those models need to be used to ask questions about the real systems of nature, and where they are headed that the models would never suggest.
How about a forum dedicated to that learning process?
