當(dāng)你聽到“農(nóng)莊”這個詞時，很可能你腦子里想象到的是鄉(xiāng)下那些遍地牛羊和谷物的連綿起伏的山崗。但有些科學(xué)家、工程師和城市規(guī)劃師說，未來的農(nóng)莊有可能會直接向空中伸展——坐落在世界上人口最多的城市的摩天大樓里。

知情人士稱把種植業(yè)引進(jìn)室內(nèi)可以解決許多問題。首先，傳統(tǒng)的種植業(yè)占用大量土地，而能自行種植食物的城市更可實現(xiàn)自給自足，且較少受到災(zāi)難（如颶風(fēng)）的影響。加之，到2050年世界人口將再增加30億。隨著人口的增加，可耕地越來越少，這就產(chǎn)生了一個嚴(yán)重問題：我們將在什么地方為這些人種植食物呢？科學(xué)家們認(rèn)為，答案是“垂直種植”——把作物種在幾十層樓高的摩天大樓里。

但熟知室內(nèi)種植莊稼困難的人士卻認(rèn)為，過渡到垂直種植并不是一件容易的事。調(diào)節(jié)室內(nèi)的氣候條件相當(dāng)困難，保持室內(nèi)適當(dāng)?shù)臐穸扔葹椴灰?，而模擬陽光的代價則太大了，還不適合推廣。

這并不意味著這些困難就不能被克服——但要克服它們還需要時間。多數(shù)專家認(rèn)為要建立起第一座垂直農(nóng)莊還需要5到15年的時間。
