What do you do?
You re-think your humane waste system - preferably before the proverbial shit hits the fan.
Some people might find the following distasteful, but hygiene is an important survival issue and this is a very effective, and ultimately more useful way of dealing with human excrement, which is usually pumped into the ocean (think about that next time you swallow some sea water).
Joseph Jenkins' book The Humanure Handbook (3rd Edition) has achieved legendary status. You can buy the book at Amazon, or read it online for free. Jenkins has also come up with The Loveable Loo, a collection toilet that looks easy to make if you have a woodworker in the house.
