The challenge of applying the concept of ecological resilience to the context of sustainable development is that it sits at odds with conventional economic ideology and policy making. Resilience questions the free market model within which global markets operate. Inherent to the successful operation of a free market is specialisation which is required to achieve efficiency and increase productivity. This very act of specialisation weakens resilience by permitting systems to become accustomed to and dependent upon their prevailing conditions. In the event of unanticipated shocks; this dependency reduces the ability of the system to adapt to these changes.  Correspondingly; Perman et al. note that; "Some economic activities appear to reduce resilience, so that the level of disturbance to which the ecosystem can be subjected to without parametric change taking place is reduced". 
4. Consentual abuse? People in relationships which involve sexual bondage, discipline or sadomasochism often insist that the mutual consentuality of these practices is what distinguishes them from abuse. Do you find this convincing? Is it possible that a practice could be abusive even if it is a practice to which a person has fully consented? Is it possible that what we ‘want’ can become so distorted by abuse that we consent to being abused? Does that make it something other than abuse? Or is it even more abusive because our consent means that we are involved as both perpetrator and victim?
