=﻿ Water's Present Use  =

= The uses of water are many, from drinking and cleaning to irrigating crops and landscapes. Water is used for cooling, for recreation, and dust control. Water is needed for restaurants, most industrial processes, and even some religi ous ceremonies. On another level, the splash and flow of water in streams and fountains soothes and inspires. In one way or another, water is a part of almost everything humans make and do. Washing a load of laundry uses 40 gallons, filling a backyard pool takes about 25,000 gallons, growing a pound of cotton consumes 1,000 gallons, while producing a pound o f copper uses 20 gallons. All these water demands are met by various supply sources including the Salt, Gila and Colorado Rivers and groundwater pumped from beneath the surface. = = = = = = Gretchen Daily, Stanford Biological Sciences = = UCI political scientist and water policy expert David Feldman =
