Plantagon: The Future of Urban Food

Find more Earth Focus content at https://www.linktv.org/earthfocus Growing food vertically in the city? The Swedish company Plantagon will show how to grow more food in less space when it opens its first urban greenhouse in 2013 in Linkoping, a city some 180 miles from Stockholm. The plan is to grow vegetables in a turning helix with minimal water, energy and the need for fertilizer. With the world's population to top 9 billion by 2050 -- and with 80% of those people projected to live in cities -- finding innovative, cost effective, and environmentally friendly ways to supply food to cities is a major challenge. Earth Focus visits Plantagon for a look at what might well be the future of urban food.
