A practice is sustainable if it can be continued indefinitely within a system.

Indefinitely? Without limit, except as posed by external events truly beyond the control of those performing the practice that change the system. Resilience describes the ability to withstand external changes to the system but relies on changes not exceeding critical limits.

Is there a limit beyond which it is not possible to continue? Assuming planet earth as the system, the sun is expected to put an upper limit on any biosphere after several billion years. Other events beyond our control that make life impossible on this planet may or may not occur. For purposes of this discussion sustainable civilization is able to continue on this planet while the sun provides a suitable environment i.e., for billions of years.
