Vertical Farming

This was sent to me by a friends. It's interesting so I thought I would pass it along.

Vertical farming is really a joke proposal. It would require massive amounts of energy to build a vertical farm, and even the daily operation would use more energy than you would save from transporting food shorter distances. This means a vertical farm would generate large amount of net carbon and contribute to global warming. It would also be much less resilient in the face of energy shortages or peak oil. However, that's not to say that growing more food in urban areas isn't a good idea. Growing food on lawns and building community gardens are both great idea.
