 True GritWe’re running out of sand.

Without sand, engineering would be stuck in the Middle Ages.  Wooden houses would line mud-packed streets, and Silicon Valley would be, well, just a valley.  Sand is the building material of modern cities, and we use more of this resource than any other except water and air.  Now we’re running out of it. 

 Granting Immunity Microbes, fungi, and T-cells.

“Diversity or die” could be your new health mantra. Don’t boost your immune system, cultivate it!
