In descending order, the most sensitive inputs were maternal milk (cubs), fruit production, and plant food availability (Figure 9.6); relatively insensitive inputs were immigration, animal food, and recruitment (to yearlings and adults). Sensitivities to outputs, lower than for inputs, were, in descending order, respiration, egestion, accidental mortality, emigration, parasitic infection, predation (on cubs), harvest, and sickness. Since the model is linear, it can be considered to represent near steady-state dynamics, but its realism suggests that the neighborhood of applicability may actually be very broad around steady state.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
