Hmmm! I think nudity is the exclusivity of other genre of living things which are not conscious of their environment; being driven by instincts.

Humanity is quite superiorly different ; which accounts for their being "secretive " about their privacies under textiles. Beside distinguishing humanity from bestiality , clothing serves as protection from inclement environmental vagaries and physical protection from imminent harms .

Nature , beside scriptures is the chief driver of "NO NUDITY " campaigns worldwide!
