Non-monetary prioritizing of problems
Although we cannot put a valid monetary value on natural processes vital to human survival and quality of life, we can rate how crucial they are to us, by present knowledge. As we learn, these keep clarifying, and we have to discover causes, for example the sources of plastic and junk in the sea.
This a rather knotty area. What we're attempting is to assign priorities such that some human processes contributing to natural imbalances have to be curtailed as fast as possible, while others can be phased in.
A crude example of this is given in Chapter 6 of Compression (about p. 238). This problem needs a great deal of study and refinement, especially if considered as a method to help people in conflict enter a dialog to resolve deeply held differences.
