P is for Phosphorus (Podcast)

Thought y'all might enjoy this Planet Money episode about P and Phosphorus https://www.npr.org/sections/money/2018/01/26/581156723/episode-820-p-is-for-phosphorus

I knew that phosphorous was used in a non-renewable way in fertilizers, but I definitely didn't realize most of our phosphorus comes from ONE country, that they keep the amount available a secret, and that we may only have a couple of decades of it left. I also enjoyed their focus on re-using pee first, since composting poo has so many complexities involved at a large scale.

Eager to hear this. Because it's NPR, I don't expect their treatment of my favorite related topic, disposing of phosphate fertilizer production waste by fluoridation, to be particularly trenchant.
