世界人口将在本月突破70亿大关,预计到2050年将超过90亿。如此多的人口,加上不断提高的生活水平,意味着全球农业到本世纪中叶将不得不将粮食产量翻一番。

然而,农业和畜牧业已经对环境造成了巨大的损害:烧毁雨林以开垦更多耕地,将肥料倾倒在田地里,肥料径流污染河流和海洋中的生物,向大气中排放大量温室气体,消耗大量淡水用于灌溉。我们怎么可能在不破坏种植粮食所需的土地、水和空气的情况下,将粮食产量增加100%呢?

一个国际研究团队设计了一个五步计划,大胆声称可以同时实现这两个目标。明尼苏达大学的团队负责人乔恩·福利在2011年11月刊的《大众科学》杂志上解释了该计划,该杂志将于10月18日星期二在线发布(该文章的预览现已上线)。福利还发布了一系列六张世界地图,展示了该计划如何运作。它包括美国中心地带,更不用说南美洲、欧洲、印度、中国和非洲的一些重大进展。
