Jon Stewart asks: Should we drink our own toilet water?

Leave it to the faux news genius to make the unthinkable both plausible, politically correct and hilarious. In an interview with Robert Glennon, author of the new book "Unquenchable: America's Water Crisis and What to Do About It", Stewart pops the obvious question in response to Glennon's description of innovative ways to reclaim potable water for human consumption from the sewage treatment process. In fact, Glennon believes, this is one of the low hanging fruit in what is rapidly becoming an urgent problem facing America.

A growing chorus of conservation voices is calling for better capture of so-called urban runoff to be used to help reduce how much water the U.S. takes out of its rivers, streams and lakes and puts through its sink, faucets and toilets. Stewart asks Glennon when the crisis will hit and the author, a law professor at the University of Arizona, basically says the crisis is already hitting and it's only going to get worse in the near term.
