Peru's Ica Valley is a hotbed for growing asparagus...and is now the world's biggest exporter of the pencil shaped veggie.
There's almost no unemployment there...and poverty is way down
But...a danger lurks...because the water table is also way down...since asparagus is a very thirsty vegetable...and the region is basically...a desert.
