In other parts of the world, the situation seems less dire.
But even in regions where water is most abundant, we lose so much of it to preventable leaks hidden behind walls and under sinks. In fact, here in the US, 10% of homes have leaks that waste over 90 gallons a day. And a study by Michigan State University reveals that in just five years, nearly one third of the US will lack affordable access to water if this trend continues.
