When people talk about the need to increase global food production to feed those nine billion people that are expected on the planet by 2050, I always think of these graphs.
Alati kui räägitakse vajadusest tõsta üleilmset toidutootmist, et toita 9 miljardit inimest, keda on 2050. aastaks meie planeedile oodata, mõtlen ma nendele tabelitele.
