Naomi Lubick quotes an estimate that $384 billion is needed over the next two decades to deliver drinking water across the US (16 August, p 38). This is a seriously scary number, at least until you work out the cost per citizen per week. This comes to about $1, or around $4 per month.
The cost equivalent of one cappuccino per month doesn’t sound quite as frightening as the full figure.
