Writing a book and one chapter is on how managing sustainability seems to be turning into a profession, with full-time managers doing this in business. What do professionals in sustainability need to know? Is there a distinct science underlying the field? If so, what does it involve? Are environmental sciences and studies programs providing adequate grounding in this science?
Please concentrate on the questions, not the definition of sustainability. There are lots of different definitions of sustainability (my book will offer another one), but for the purpose of this discussion, please assume that "sustainability" means doing business and managing enterprises in a way that works toward the goal that there is minimum impact on the environment, good prospects for the future, no degradation that would compromise the future, and that protects health and a decent life.
