Document Summary

It integrates this idea of systems thinking and it"s an approach as to how you think of an area. Systems thinking in ecology; ecosystems are nested and hierarchical (ex: there"s a river; this exists in a bigger landscape and so on and so forth) You can look at what the inputs/outputs, feedback loops are in the ecosystems. There is no such thing as a completely closed system, as at some point, energy must get into the system (whether it"s through solar energy, heat, etc) If you think of a pond, it"s more closed than looking at a river for example (where there"s more water coming in and rushing out) Some systems are most closed and some are more opened but none is completely ever closed. Resistance = system resists change and remains stable despite a disturbance. > the idea that you"re able to resist for example if someone pushes you and you don"t fall.
