The Devil’s Element is a tale of folly, waste, greed, and excess, which Egan unspools with a light touch and a brisk pace. He opens the book with a police foot chase; the unfortunate suspect is eventually fished out of an algae-choked canal and hospitalized in Cape Coral, Florida. In its final pages he describes a pilot project to capture phosphorus from the pee of residents of Brattleboro, Vermont, and its use of an educational video featuring a talking drop of urine named Uri Nation. Along the way we meet Hennig Brand, an alchemist who first succeeded in isolating pure phosphorus from urine in 1669 while searching for the philosopher’s stone, the mythical substance that could turn lead to gold. Others quickly discovered that while the waxy, glowing stuff did not produce gold, it was poisonous, extremely unstable as a solid at room temperature, and prone to exploding. These properties earned it the moniker “the Devil’s element,” which in turn presaged its other modern application as an ingredient in some of the most horrendous weapons that humans use on one another. (Egan writes about a German beachcomber whose leg began to melt and char after a small orange rock he had collected exploded in his pants—a pebble-size legacy of the Allied firebombing of Hamburg in 1943 washed up on a Baltic shore.)
At the outset of the Industrial Revolution many nation-states figured out that they couldn’t feed their fast-growing populations without finding a lot more phosphorus than was available from manure and crop residues and naturally occurring in soils. Egan gives a grim global tour of the various predatory lengths to which imperial powers and modern multinational firms have gone to secure phosphorus. Soon after the Battle of Waterloo the British dug up their own fallen soldiers’ phosphorus-rich bones, shipped them home, then heated and ground them up as fertilizer to grow food for the living. In the middle of the nineteenth century, European and American farmers became reliant on imports of guano (bird poop) strip-mined from Peruvian islands by indentured Chinese laborers. When those reserves were exhausted in the 1890s, they turned elsewhere. Thus began the century-long ordeal of the Banaba Islanders, displaced from their Pacific homeland by the voracious English-owned, Australia-based Pacific Phosphate Company. After a company agent discovered vast reserves of phosphorus-laden rock on Banaba one day in 1900, the firm’s miners carved up the island chunk by chunk. The rocks were carried by conveyor belt to ships that ferried them onward to fertilize fields around the world. Banaba’s destruction helped Australia and New Zealand boost the productivity of their soils and become wealthy agricultural exporters. After the late 1970s Banaba’s phosphate reserves were largely depleted—by that point, mining firms had stripped 90 percent of the island’s land surface and removed 22 million tons of material. In the process, they also ruined many of the sacred caves where the islanders had collected water to survive periods of drought.
