Melinda Burns in Miller-McCune:
Unremarked and unregulated by the United Nations and other high-level assemblies, the world’s supply of phosphate rock, the dominant source of phosphorus for fertilizer, is being rapidly — and wastefully — drawn down. By most estimates, the best deposits will be gone in 50 to 100 years.
Worse, phosphorus production could peak in just two decades, according to new research from Australia and Sweden. That’s when demand could outstrip supply, playing out a familiar scenario of scarcity, price shocks, riots, starvation and war.
In short, peak phosphorus could be the unwelcome sequel to peak oil.
