Interesting article on phosphorus, while everybody’s worried about oil, carbon, and all the technology-critical elements used to make smartphones.

«To meet our demands for energy, humankind has moved masses of carbon from deep underground into the atmosphere, wreaking havoc with the climate. To meet our demand for food, we have moved large amounts of nitrogen from the atmosphere to fields, rivers and forests, devastating ecosystems. To grow our crops we have interfered with Earth’s reserves of a third element — phosphorus — which receives much less press and for which we face the unique problem of having both too much and too little.»
