005 - Water Resources
In this video Paul Andersen explains how water is unequally distributed around the globe through the hydrologic cycles. Seawater is everywhere but is not useful without costly desalination. Freshwater is divided between surface water and groundwater but must me stored and moved for domestic, industrial, and agricultural uses. Subsidized low cost water has created a problem with water conservation but economic changes could help solve the problem.
