What might life look like on this planet, after we add several billion more people? Glass curtain buildings covered in lettuce. Not bad. 

Gizmodo takes an in-depth look at MIT's Media Lab, the "plant factory" CityFARM, which is experimenting with aeroponic plant growth by indoor farms originally designed to grow food in space. The tactic minimizes waste and expands and accelerates food production with computer-regulated nutrient dispensers, misters, and LED growth lamps deliver precise portions of substinance for vegetables and lettuce to grow at breakneck speed. CityFARM founder Caleb Harper is still toying with ideas like personal growth boxes, or a growth system monitored by a city-wide supercomputer, but in any case, this is what we're dealing with now. 

Bonus: they'll also be genetically "curated" for flavor.
