@Merry Andrew,
Andrew & Tai
That was a cartoon from yesterday's Age newspaper (Melbourne, Oz).
With the continuing (never ending?) drought & water shortages, we are absolutely
obsessed (!) by what are we going to do if it doesn't rain (
like crazy!) soon? People are investing in home water tanks, the state government is investing in a huge desalinization plant, there are fueds between the country & city about water being diverted to the city .... you have no idea!
So this cartoon is a tongue in cheek depiction of one of the many, many suggested solutions: The conversion of human urine into drinking water. Pretty nifty invention!
Glad you enjoyed it.
Sorry to digress from your topic, edgar, but I couldn't help myself!
