Example – Suppose your topic relates to water:
The entire modern economic system is based on abundant and readily available clean freshwater. Human survival depends upon readily available safe drinking water; freshwater-based industries depend on stable water levels, and many of the world's river-borne transport routes share the freshwater industries' reliance on stable water levels.
Yet while water appears abundant to the casual observer, many climatic and human influences disrupt water quality and supply. Some of the effects on water include: reservoir evaporation, falling lake levels (and shrinking lake boundaries) due to damming and other diversions of the rivers feeding the lakes, loss of wetlands to engineering projects (swamp drainage, "claiming" marshlands for expansion of neighborhoods and business districts), soil nutrient depletion (resulting from stemming natural seasonal river delta flooding) which brings reduced plant life and in turn leads to receding shorelines, increasing salt content in coastal estuarine waters, and environmental contamination.
Such changes to water affect every area of life: public health, ecosystem health, agriculture and crop success (or failure), and economic health. Vantage points include politics, economics, social justice issues, ecosystem issues, legal actions, and more.
