NPR finds out why US per capita water demand is down nearly a third in thirty years
Friday, November 20th, 2009
Peter Gleick (rhymes with click) is a water and resource specialist at an outfit in California called the Pacific Institute where for many years he’s been a solid source for reporters wanting new detail about how mankind is messing things up – particularly via a changed climate’s impact on natural hydrology. (He is also, by the by, younger brother to well known science writer James G). This week NPR, via an interview with Renee Montagne on Morning Edition, gave Gleick a chance to say something optimistic and somewhat admiring about our collective behavior. Led by reforms in industry and agriculture, US water consumption per person, if not in absolute numbers, has dropped considerably in recent decades.And this despite the move by so many people to the Southwest to buy big sunny houses and to plant large lawns with big sprinkler systems.
Did you know, for instance, that 70 years ago smelters and mills went through 200 tons of water for every ton of steel they produced, but now it’s more like three or four tons of water? It’s not a long interview butit serves to remind listeners that at last once in a while market pressures, gov’t regulations, and private innovation work well as a team.
