where will we get enough phosphorous
Bat Shit
fun fact..there are more bats living in Austin Texas than there are people.
there MIGHT be more bats living in the USA than there are people too.
NOT a scarce resource..
(collection is rather tricky...perhaps an inflight removable diaper collected by drones needs to be invented?)

There is not enough natural manure to provide as much phosphorous as we mine, even including humanure. Most of the large guano deposits have been mined out, there were war fought over it.
