Industrial Interest in The Dune Fields
The several million tons of sand in the Salamayuca dunes can be considered as an enormous potential of silica sand since they are 90 to 95 pure silica (SiO2). Silica sand is widely used in what is called "the transforamation industry", for the making of glass, silicates, paints, glass-ceramics and ceramics. The sand of the Salamayuca dunes has attracted attention from the ceramic/glass industry but the desert sand contains sufficient impurities to pose problems with its use in industry, and a process to increase uniform purity to 97.5% SiO2 would have to be developed. Because the sands start with such a high percentage of silica, such a process is deemed feasible.

“Christianity as an organized religion has not always had a harmonious relationship with the family. Unlike Judaism, it kept almost no rituals that took place in private homes. The esteem that monasticism and priestly celibacy enjoyed implied a denigration of marriage and parenthood.”
—Beatrice Gottlieb, U.S. historian. The Family in the Western World from the Black Death to the Industrial Age, ch. 12, Oxford University Press (1993)
“The cohort that made up the population boom is now grown up; many are in fact middle- aged. They are one reason for the enormous current interest in such topics as child rearing and families. The articulate and highly educated children of the baby boom form a huge, literate market for books on various issues in parenting and child rearing, and, as time goes on, adult development, divorce, midlife crisis, old age, and of course, death.”
—Joseph Featherstone (20th century)
“Like a man traveling in foggy weather, those at some distance before him on the road he sees wrapped up in the fog, as well as those behind him, and also the people in the fields on each side, but near him all appears clear, though in truth he is as much in the fog as any of them.”
—Benjamin Franklin (1706–1790)
