Sustainability thoughts 144: Linking sustainability line theory and supply and demand theory to point out the nature of sustainability problems and of unsustainability market zones separating sustainability and unsustainability-based markets

Sustainability line theory in terms of markets tells us that market sustainability varies from 0 to 1 or from full unsustainability markets to full sustainability markets and that each market located on the sustainability line has a supply and demand configuration that goes with it. This sustainability line idea in terms of market thinking can be expanded step by step to show the following in terms of supply and demand theory: i) The location of full unsustainability markets and of full sustainability markets; ii) The possible contractions and expansions of sustainability markets; iii) The possible contractions and expansions of unsustainability markets; iv) The nature of the sustainability problem separating full sustainability markets and full unsustainability markets; v) The nature of the unsustainability market zone separating full sustainability markets and full unsustainability markets; and vi) The expected expansion of unsustainability markets and of full sustainability markets once they are in place. The overall goal of this paper is to described how this step-by-step expansion of the sustainability line idea in terms of supply and demand theory works as well as to highlight the relevant implications at each step.
