Recently I had the opportunity to visit The Plant, Chicago's first vertical farm. This claim depends on your definition of vertical farm, of course, because The Plant isn't the sort of futuristic vegetation-filled skyscraper you might expect, and it isn't solely agricultural. While food will be grown there, the space will also house small food-related businesses, breweries and bakeries and the like, so it might be more accurate to classify it as a "food business incubator." Whatever you call it, The Plant is definitely an example of innovative green food production, with the ambitious goal of being net-zero energy and net-zero waste by 2015.
With the US unemployment rate hovering around 10 percent, and the UK unemployment rate stuck at about 8 percent, most people are worrying about what job they'll have 20 days from now, not 20 years in the future.
