From The Unhabitable Earth by David Wallace-Wells pg 89:
Sitting in a living room in a modern apartment in an advanced metropolis somewhere in the developed world, this threat may seem hard to credit—so many cities looking nowadays like fantasies of endless and on-demand abundance for the world’s wealthy. But of all urban entitlements, the casual expectation of never-ending drinking water is perhaps the most deeply delusional. It takes quite a lot to bring that water to your sink, your shower, and your toilet.
