the california aqueduct below enables southern california (SC) habitability; it is an engineering wonder (bc so bad, it makes you wonder)
the demand never satisfied caused towns to be abandoned and rivers run dry
this, combined with the eco-disaster that is the central valley (CV)
over-fertilization is actively salting the soil, attempts to fix it caused mass die-offs in the salton sea
over-pumping CV aquifer caused land sinkage in areas
calling this unsustainable is an understatement
