Vertical Farming
Real estate — the one thing we're not making any more
of. That might be good news for landlords but not for the
world's farmers, who have finite cropland to feed a growing
global population. The answer: build up by farming vertically.
Valcent, a company based in El Paso, Texas, is pioneering
a hydroponic-farming system that grows plants in rotating
rows, one on top of another. The rotation gives the plants
the precise amount of light and nutrients they need, while
the vertical stacking enables the use of far less water than
conventional farming. But best of all, by growing upward instead
of outward, vertical farming can expand food supplies without
using more land.
