Sustainability Principles Online Dialogue

I think we can substitute the word wealth for sustainability in the definition. Just maybe- wealth and sustainability mean the same thing. I can't think of a difference. I'll look into definitions written by others. I haven't read any of them so far.

In the Intro. section, Michael says there is an operational definition for each of the five principles. Are these operational definitions available?

Waht do you think about how Sustainability is defined?
