I admit that on occasion I've bought bottled water, for example on long road-trips. But I've also found it amusing that Evian backwards spells...well, you can figure it out. The Economist this week explains why, exactly, buying bottled water shows consumers are daft:
The success of bottled water is in many ways one of capitalism’s greatest mysteries. Studies show consistently that tap water is purer than many bottled waters—not including those that contain only tap water, which by some estimates is 40% of the total by volume. The health benefits that are claimed for some bottled waters are unproven, at best. By volume, bottled water often costs 1,000 times the price of tap water. Indeed, even with oil prices sky high, a litre of bottled water can cost more than a litre of petrol. And on top of that, there are the environmental costs of transporting bottled water and of manufacturing and disposing of the bottles.
Yet sales of bottled water have been booming. In 2006 Americans spent nearly $11 billion buying 31.2 billion liters of the stuff, an increase in volume of 9.5% on a year earlier. The average American drank 104.5 L of bottled water last year, up from 63.2 L in 2000.
All of which shows the problems of the average IQ being 100.
