Interacting "things" are constantly moving, changing and/or evolving. For example, humans, animals, and plants are all living organisms, which need to constantly consume nutrients. The flow of nutrients (foods), resources, energy, goods, materials, etc, is a large part of "context." I think it is important to be aware of this "flow" and how the "flowing things" relate to each other and with other components within the context. I believe that many environmental crises have been caused, at least partially, due to the ignorance of these flows and relationships.
