The SiD Definition of Sustainability
Sustainability is the state of a complex, dynamic system. In this state, a system can continue to flourish resiliently, in harmony, without requiring inputs from outside its system boundaries.
Applied to our civilization, this state is consistent with societies powered by renewable energy and closed-loop material systems, inhabiting thriving ecosystems, on a biodiverse planet, with healthy and happy individuals living in just, tolerant, and diverse cultures, supported by open and transparent economies.

If you understand why the definition is formulated this way, you’ll grasp the most important lesson in this course.
