Phosphorus sustainability

October 18, 2011 – 3:03 pm

Sustainability issues surrounding phosphorus have been getting some attention recently, including an interesting commentary piece (requires sub) in Nature. Phosphorus problems are a combination of the problem we have with nitrogen – too little hinders food production, too much degrades environment – and the problem we have with oil, a valuable finite resource that corrupts the few locations in which large supplies are found.

One particularly interesting part was this graph suggesting that while data show that Morocco is the Saudi Arabia of P, wildly fluctuating estimates indicate that in actuality we have no freaking clue how much mineable P exists.
