Bioengineer Karsten Temme discovered a remarkable answer to this question: for eons, crops relied on soil microbes to convert atmospheric nitrogen into food — until modern farming severed that ancient partnership. He shows how we can reawaken those dormant microbes using gene editing, creating “living fertilizer” that delivers nutrients to crops in real time and transforms farms around the world.如果养活人类的解决方案，已在土壤中潜藏了数百万年之久，会怎样？生物工程师卡斯滕·泰默（Karsten Temme）发现了一个引人注目的答案：亿万年来，农作物一直依靠土壤中的微生物将大气中的氮转化为养分——直到现代农业割断了这一古老的合作关系。他向我们展示了如何利用基因编辑技术重新唤醒那些休眠的微生物，制造出“活体肥料”，实时为作物输送养分，并由此改变全球各地的农场。
