Document Summary
The figure above provides a graphical depiction of how we will conceptualize scale", as in geographic proportionality". At the smallest scale, we have a site-specific process, e. g. , toxic wastewater being emitted from a sewage pipe. This site-specific process is nested within a local scale, e. g. , the lake into which the pipe is being drained. The local scale is situated in a regional context, e. g. , the watershed that drains into and out of the lake. And this regional context is part of a global process; e. g. , the global water cycle and the global economic markets for which the plant is manufacturing products. Each scale is represented by an increasingly larger perforated oval to indicate that the boundaries are not fixed nor are they hard . Furthermore, it is important to note that the relationships across these scales are not deterministic .
