Wu learned that Indonesia produces 350 thousand tons of coffee a year, making it the fourth largest producer in the world; that 2 million hectares of Sumatra's rainforest was disappearing every year; and that the natural resources that Taiwan consumes would require 29 Taiwans to supply-a fact that made him an "environmental exploiter" himself. Armed with this new knowledge, he decided to do something for Indonesia's benefit.
在得知印尼年產 35 萬公噸咖啡、是全球第 4 大原豆出口國，而蘇門答臘的雨林卻以每年 200 萬公頃的速率消失中；更在驚覺台灣現階段生活消費所需資源來自全球，必須要耗用 29 個台灣才足以支撐，自己也是環境的「剝削」者時，吳子鈺決定要為印尼 do something。
