Keeping agriculture sustainable increasingly means keeping it local. Besides the environmental benefit of reducing reliance on fossil-fuel guzzling transportation, eating local food is a more seasonal and often healthier experience. With concern about food security growing, it might turn out to be safer, too. The folks in charge of the Science Barge, a new urban farming experiment in New York, are bringing local food production closer than ever. In this video Vanessa Rae learns about the floating greenhouse facility, which is designed as a demonstration of how urban space, especially rooftop space in big cities like New York, can be used to efficiently produce food. Self-powered by solar panels, wind turbines, and a biodiesel generator, the Science Barge uses state of the art computer technology and an agricultural technique called hydroponics to grow fruits and veggies using much less water and space than field farming. Watch out, city slickers. Farm country is coming to your neighborhood.
