It's not often that you go to an airport and find really good, fresh food to eat while you're beginning a trip or in transit. Most travelers settle for quick and dirty fast food options (Cinnabon, anyone?) while making a connecting flight. More often than not the impetus to purchasing food in the terminal isn't because it's good for you; it's simply because it can be cheaper than paying the outrageous prices airlines charge for those small mid-flight snack packs.
However, if you're yearning for a healthier option and transiting through Chicago's O'Hare International Airport soon, check out their recently debuted one-of-a-kind vertical vegetable garden between terminals 2 and 3. The garden will provide restaurants with over 45 different kinds of herbs and vegetables and uses a unique "aeroponic" system that relies less on traditional soil and more on an efficient water and mineral solution that allows the plants to grow in a controlled environment. The planting towers employ vertical technology that is not only a space-saver, but also allows more food to be grown in a smaller area. The system also recycles its own water as well as water in the airport.
Of course, the restaurants that will take advantage of this local garden are some of O'Hare's better establishments, and not necessarily fast food joints. Still, it's a step in the right direction. The company backing the project is in charge of most of the airport's concessions; when you stop and think that O'Hare is the second biggest airport in terms of passenger movements in the United States, it's a huge statement for the future of food.
