Why do you want to be a NA'Vi on Pandora?

You are crazy!
This is the BEST thing we've invented.
Fecal matter is fetid waste. It stinks, and is full of bacteria. Treating it and getting rid of it makes people healthy. Diseases like cholera come from untreated and undisposed human waste. Ever notice how backwards countries have lifespans 2/3 to 1/2 what developed nations have? These nations usually have open pit latrines, and even a cat knows to bury its waste.
As for 'waste of water', toilets without water have been tried, with little success, or great expense. And besides, where I live, we get about 39 inches of rain a year, or about 1+1/3 meters. We have to worry more about getting rid of the excess water than conserving.
As for my earlier points, you may consider 'creature comforts' unnecessary, but why live without them when you don't have to? Life is safer.
