J. MILSUM states: “… the particular dynamics and parameter values of the loop… are critically important in determining its stability” (1968, p.46).
Either positive or negative feedbacks may, in the long run, destabilize a loop and, finally, destroy it. A reiterative and not compensed positive feedback leads to a destructive runaway event: an out of order thermostat may induce a fire, which will destroy the regulation loop.
A not compensed negative feedback finally annulates any regulation and drives the loop out of existence: once past a certain point of decay, the renewal cycle of a population may disappear (and the population together with it).
