Over at The Vertical Farm, they've got some very interesting info for you. For instance, these folk are advising that within the next 40 years, we'll be facing the basic need of feeding around 3,000,000,000 (three billion) mouths.
We can't do it with the farmland we've got now. Problem. Unless we get creative and farm differently. One solution: vertical farming.
Which, yes, is something a lot more complicated that the Baker's Rack Vegetable Garden I tried to grow long ago on the apartment balcony -- but at least I got that footprint idea right ....
It sounds pretty darn smart - especially the recycling aspects, and the idea of safe water and safe food.
