Well scratch that theory! I really hope you have room at your place for that thing cause ouch.
I suppose if you're that poor and water's such a precious resource it makes sense to farm it?
Could be true. If it pees (which I presume it does) it needs water and if its natural habitat is a desert it makes sense it would have adapted a way to filter water from the atmosphere. Now, if those farmers were really smart, they'd be farming Banthas and filtering their pee instead of trying to get it out of the air.
