世界人口將在本月突破70億大關,預計到2050年將超過90億。如此多的人口,加上不斷提高的生活水平,意味著全球農業到本世紀中葉將不得不將糧食產量翻一番。

然而,農業和畜牧業已經對環境造成了巨大的損害:燒燬雨林以開墾更多耕地,將肥料傾倒在田地裡,肥料徑流汙染河流和海洋中的生物,向大氣中排放大量溫室氣體,消耗大量淡水用於灌溉。我們怎麼可能在不破壞種植糧食所需的土地、水和空氣的情況下,將糧食產量增加100%呢?

一個國際研究團隊設計了一個五步計劃,大膽聲稱可以同時實現這兩個目標。明尼蘇達大學的團隊負責人喬恩·福利在2011年11月刊的《大眾科學》雜誌上解釋了該計劃,該雜誌將於10月18日星期二線上釋出(該文章的預覽現已上線)。福利還發布了一系列六張世界地圖,展示了該計劃如何運作。它包括美國中心地帶,更不用說南美洲、歐洲、印度、中國和非洲的一些重大進展。
