Which Way Goes Desire

When we talk about the availability of water resources, we assume 0.5+ acre foot per person.  
As people f.... and population increases, the question for Arizona is whether our sexual desire will overcome our thirst. 
That's an interesting question. 
The disturbing complexity is that thirst will kill us and sex, or the lack of it, will make life unpleasant.  
There's a finite limit to Arizona's water...a finite limit to population hasn't been found.
If you need it spelled out, a growing population will have effects on water use.
You can pick up sex at the local grocery store.  Wanna quible about water?
