Mar 29, 2016· Phosphorus is naturally weathered out of rocks and slowly gets transported to the oceans. Mining phosphate rock can accelerate this process and also leave scars on the landscape if the mining companies don't do reclamation. Exposed phosphate rock will also weather and erode more quickly, again speeding up delivery of phosphorous to the oceans.
