The first law of thermodynamics states that all energy in the universe is constant, that it cannot be created or destroyed; only its form can change. The second law states
that energy can only be changed in one direction, that is, from usable to unusable, from available to unavailable, or from ordered to disordered.Entropy is the measure of the extent to which available energy in any subsystem of the universe is transformed into an unavailable form.
Accumulation of entropic debt will eventually collapse whatever economic regime is harnessing the resources.
