You’ve probably never heard of this crisis. After Peak Oil comes this news about Peak Phosphorus. Supposedly, this element, a key component of the global food chain is to run out in 30 years and a lot of people are concerned because “Our dwindling supply of phosphorus, a primary component (mainly as fertilizer) underlying the growth of global agricultural production, threatens to disrupt food security across the planet during the coming century. ” Simply put, farmers will run out of fertilizers for their crops.

This is the gravest natural resource shortage you’ve never heard of.
