Want to Save Water? Get Vertical!

I recently became a subscriber to Time Magazine, among a few other choice periodicals. My subscription proved quickly justified by a story in their December 22nd issue on Vertical Farming.

According to the article, vertical farming allows us to grow around 15 times more produce per acre than good 'ole conventional medieval farming. They used lettuce as an example, and I'm guessing quantities may vary depending on the type of produce. But here's another stunner from the article: Time's reporter claims that vertical farming uses just 5% of the water that conventional farming does. 5%!

In a world fraught with perilous premonitions about the predicaments of people (particularly the pending water problem), this idea is... well... almost too good to be true. This is an idea that warrants development. Let's all get on the bus and start building Wall Street high rises for growing lettuce, instead of bad debt and golden parachutes.

Computer-age gurus that you are, I hardly need to explain that further information can be found by entering "vertical farming" into your Google engine; or if you're looking for easy, by clicking here and here.
