"In the past, trees would extend their roots deep into the earth to get a little more nitrogen to help themselves grow," says Lin. "But now nitrogen is too easy to come by. Plants don't need to expend the energy to put down stable root systems.
「過去林木為了取得多一點『氮』來幫助成長，根部會拚命往地底下伸展，但現在氮的取得太容易了，植物不需要花這麼多力氣向下穩穩扎根，等到風災、雨災一來，林木當然就變得容易連根拔起而死亡！」
