As a Mormon child I sang: "O ye mountains high, where the clear blue sky Arches over the vales of the free, Where the pure breezes blow and the clear streamlets flow, How I've longed to your bosom to flee! O Zion! dear Zion!"
Well, Zion's sky is no longer blue, and its breezes are impure.
Utah's Mormon Legislature famously required that restaurants build "Zion curtains" to protect citizens' eyes from seeing mixed drinks, but it's darn reluctant to do much about protecting their lungs from the air they breathe.
