Watch Urban Roots (2011) : Full Movie Online Free URBAN ROOTS is a documentary that tells the story of the spontaneous emergence of urban farming in the city of Detroit. Detroit, once an industrial powerhouse of a lost American era, is a city devastated by the loss of half its population due to the collapse of manufacturing. By the looks of it, the city has died. But now, against all odds, in the empty lots, in the old factory yards, and in-between the sad, sagging blocks of company housing, seeds of change are taking root.
