Guano 海鳥屎–War of the Pacific太平洋戰爭

昨晚睇咗一套非常好的紀錄片Chris Tarrant Extreme Railway Journeys Series 2  Crossing the Andes 安地斯山脈.

在影片開頭,  Chris 介紹了他要去睇 Nitrates Mine, 在19世紀Nitrates又叫white gold, 非常值錢是用來製造 gun powder 的 guano (海鳥屎含豐富的硝酸鹽). 

guano:  The word "guano" originates from the Andean indigenous language Quechua, which refers to any form of dung used as an agricultural fertilizer.
就是裡d 海鳥屎引起了War of Pacific,
自1883年後, 玻利維亞失去出海口,成為內陸國.
我知道雀屎都有用的時候, 是我睇咗 Nauru: An Island Country Destroyed by Phosphate Mining:  
不過, 佢地叫雀屎為phosphate, 唔係guano.
