Vertical farming stacks crops on top of one another in a climate controlled, indoor facility, using aeroponic technology, which involves misting the roots of the plants, using an astonishing 95% less water. The plants are grown organically, in a reusable cloth made from recycled plastic, so no soil is needed. What’s cool is that the technology is mature… it actually works on pragmatic and commercial scales, at least for table greens. Doubtless there are some crops that won’t apply. But this — plus tissue-culture meat — could loosen humanity’s death grip on the planet’s arable land, just in the nick of time, and make our cities much more sustainable.
