The Water Crises Aren’t Coming—They’re Here

Esquire: “For eons, the earth has had the same amount of water—no more, no less. What the ancient Romans used for crops and Nefertiti drank? It’s the same stuff we bathe with. Yet with more than seven billion people on the planet, experts now worry we’re running out of usable water. The symptoms are here: multiyear droughts, large-scale crop failures, a major city—Cape Town—on the verge of going dry, increasing outbreaks of violence, fears of full-scale water wars. The big question: How do we keep the H20 flowing?…”

Water cannot be created or destroyed; it can only be damaged. When Peter Gleick says we’ll never run out, he means that at some point, millions of years ago, there was all the water there is, a result of the law of the conservation of matter. Having evaporated from lakes and rivers and oceans and returned as snow and rain, the water we consume has been through innumerable uses. Dinosaurs drank it. The Caesars did, too. It’s been places, and consorted with things, that you might not care to think about. In theory, there’s enough freshwater in the world for everyone, but like oil or diamonds or any other valuable resource, it is not dispersed democratically. Brazil, Canada, Colombia, Peru, Indonesia, and Russia have an abundance—about 40 percent of all there is. America has a decent amount. India and China, meanwhile, have a third of the world’s people and less than a tenth of its freshwater. It is predicted that in twelve years the demand for water in India will be twice the amount on hand. Beijing draws water from an aquifer beneath the city. From being used faster than rain can replenish it, the aquifer has dropped several hundreds of feet in the last forty years, and in places the city is sinking four inches every year…”
