via : treehugger. June １７. 2008.加拿大Guelph大學進行為期五年的傳統牧場有機化研究, 評估報告指出 產量減少10.6%之外, 有諸多利益：
However, chemical costs for fertilizers and antibiotics are wiped out, and veterinary costs are cut in half, saving almost $2,000 per cow.
Also, organic milk sells for 25% more than conventional milk, almost completely balancing it out.
有機事業沒人在大原則上反對,
只是如何做是很大困擾!
Tell me how to do, please.
