Vertical farming takes the old idea of a greenhouse and stretches it upwards so that the available growing area is a multiple of the building footprint, as opposed to the 1:1 ratio from a typical greenhouse. A vertical farm building would be a supremely green building because its inhabitants would be (literally) green.
Vertical farming could allow extended growing seasons. The food could be grown organically, and herbicides and pesticides could be eliminated. There would be an enormous reduction in crop loss due to weather and pest damage.
Vertical farming would allow food production to be closer to urban centers, meaning food could be provided with lower transportation and distribution costs.
There are many problems that would need to be addressed to make something like this a practical and wide ranging solution. Housing is already a problem. Extending the construction industry to provide the resources (both material and labor) to build towers for farming would likely push up the cost of all building. The costs and tradeoffs may not yet make this a practical idea, but its day may be coming.
