A) Which sicko wants to live in a desert ?
Ever been to one?
No, why would I go there ? To get killed by the sun and rattlesnakes ?
B) Aren't they running out of water there at some point in the next few years if this growth continues ?
Two feasible solutions have been proposed:
1. A pipeline that feeds from a deeper point in Lake Mead can be constructed, given that the current ones will soon start sucking air if the water levels continue to drop.
2. A pipeline that feeds from the underground water tables upstate can be built. Expensive, and the rural communities are already manning the trenches in opposition, but I can see this happening in the next few decades anyway.
Also, a law was passed back in 2006 banning new houses from having lawns or gardens that require water to maintain.
What about a pipeline from the Pacific Ocean to Las Vegas ?
