You’ve heard alarmist claims about the world running out of oil, but how about fertilizer? Strange as it may sound, an article in the journal Nature recently made the claim that there is an impending shortage of two important fertilizers to feed the world’s people: phosphorus and potassium. But according to science expert Vaclav Smil of the Breakthrough Institute, the U.S. Geological Survey recently reported that phosphate rock reserves from nations like Morocco, Russia, and Algeria will supply farmers for at least 370 years. And with industry estimates now at a whopping 600 years for minable potassium, here’s hoping this hype about vanishing fertilizer stops spreading like manure.
