  16. Is there an “environmental problem” at BJW?

  17. What do we need to know? • Components • What “stuff” can we measure? e.g., water, biomass, pesticide, numbers of marigolds or salamanders, student visitors (education) • Where is that “stuff”? = compartments • Exchanges • How does “stuff” move among compartments? • Influences • What controls rate of movement of “stuff”?

  18. BJW System Diagram • Outline the major components of this system • What is the system? BJW? What does that mean? • ID Stocks, Flows, Influences • Where do your questions fit into this system? • Which component is the focus of your question? • What other components will influence the answer? • Do other questions arise as you build the system? • The answer to your question depends on answers to others?

  19. Sustainability • “meeting the needs of the present without compromising the ability of future generations to meet their needs.” • from Our Common Future • Brundtland Commission, W.H.O. 1987
