The phosphate was formed by the excrement of seabirds which for ages and ages have stopped and rested on the island while flying across the Pacific. The excrement they left behind turned into a rich layer of phosphate, spread across the island.
古早以前，太平洋上的海鳥飛經諾魯總會停棲休息，它們留下的排洩物經過千百萬年之後，形成一片十分肥沃的礦產，遍佈全島。
