估中咗係reference 緊susan subak 1999年份paper
Subak, S. (1999). Global environmental costs of beef production. Ecological Economics, 30(1), 79–91. doi:10.1016/s0921-8009(98)00100-1
佢個table 係將所有crop 生產嘅carbon uptake 嘅opportunity cost 計晒入去。但crop 本身作為carbohydrate 嘅carbon capture 呢點就喺第三點- evaluating the environmental impact (p.83 ) 度hint 自己factor in 唔到所以唔計
