PITY THE POOR MALTHUSIANS:

If vertical farming takes off the way its supporters believe it should and will, it may solve many of the aforementioned challenges facing agriculture.

Crop yields with vertical farming far exceed what's possible with traditional agriculture. Plenty, Inc.'s Shireen Santosham notes that the highly controlled growing environment of vertical farming has allowed her company to reduce the growing time for some crops to as little as 10 days. Without needing to consider weather or even sunlight, combined with the ability to operate 365 days a year, their system increases the potential annual yield by about 700 percent.

The land requirement for vertical farming is a mere fraction of that for traditional agriculture. Santosham says it can be done in a building the size of a big-box retail store that can be built pretty much anywhere that has adequate utilities, including within major urban centers. The tightly controlled environment of a vertical farm should also eliminate the need for applied pesticides.

Yet another benefit of vertical farming is the return of land currently needed for food production back to the planet. This could help facilitate Earth's recovery from deforestation and return much needed habitat to threatened or endangered species. Of course, if we ever colonize the moon or Mars, vertical farming will be the go-to option for feeding the colonists.

Several vertical farming company pioneers are already getting their high-quality crops into the hands, and mouths, of consumers. Plenty, Inc. has an eponymous line of greens, and Aerofarms has their FlavorSpectrum line. Both companies claim that their products are exceptionally tasty, a result of their carefully controlled growing environments in which computer-controlled lighting can be optimized to bring out the most desirable qualities of each crop.
