"Nitrogen fertilizer is a disaster. Abandoning it would be a bigger disaster. Now a dozen billionaires are funding an alternative."
"Issac Christiancy was a white-bearded 79-year-old when the shooting over nitrogen started.
It was January 15, 1881, and the U.S. envoy to Peru had to duck for cover. Bullets whizzed through a suburb of Lima, “pattering thick and fast upon the buildings around us,” he later wrote back to Washington, D.C. Christiancy fled, throwing himself over walls and wading through ditches over an eight-mile run as shells from Chilean gunboats exploded around him, until he stumbled into his offices. Peru soon surrendered, and the night that followed was “a nightmare of chaos and unutterable horrors” as the remnants of the defeated Peruvian army looted, burned, and terrorized the city.
Chile had invaded Peru for a seemingly unlikely prize: nitrogen fertilizer. Twenty years earlier, the great European powers and the United States had come to the brink of global war over three tiny islands off the coast of Peru covered in mountains of nitrogen-rich guano. Why would anyone come to blows over piles of bird crap? Because nitrogen gave these countries the power to feed their growing populations. Peruvian guano was, as one historian put it, “worth more than all the gold shipped back to Europe in the Spanish treasure galleons.”"
