 The fourth major water crisis in human history is at hand, according to David Sedlak, author of a book called Water 4.0: The Past, Present, and Future of the World's Most Vital Resource.
Sedlak's view is that today's urban water systems are the result of
responses to three major water crises from the past. Now, he says, we're
about to face a fourth crisis, as urban water systems are strained by
both population growth and climate change. All of this is discussed in
this Vox article, as well as three fixes Sedlak believes may help us deal with the new crisis: water recycling, desalination, and decentralization.
