Why are watershed maps useful to environmental planners and other local decision makers in delineating appropriate places for preserving natural systems and eschewing economic development?
What will be an ideal response?
Watersheds are areas linked by a common drainage system. By delineating entire watersheds for preservation, environmental planners ensure that none of the land or waters within the watershed will be negatively impacted by development. This means the entire system will be less likely to be polluted or face other impacts.
