If steps are not taken to curb the depletion of phosphorus, we can expect to see food prices sky-rocket as countries like Morocco hike up the price-tag on phosphorus exports. Thankfully, there are ways to make supplies last. Many of these consist of modifying the highly wasteful practices of the agricultural industry. For example, controlling the erosion of crop fields would maintain phosphorus levels in soil, reducing the need to re-apply.
