Urban Roots is a documentary about farming within the city limits of Detroit, and as such, it’s a handy way to get an education on the subject in something like 90 minutes.

It’s showing March 6 at the San Francisco Green Film Festival.

Also, Shepard Fairey made the poster for the film, so even if you can’t be bothered to get your hands dirty, at least you can support the cause by spending $60 on a print of someone else’s picture with a Photoshop filter applied.

Urban Roots shows dedicated Detroiters working tirelessly to fulfill their vision for locally-grown, sustainably farmed food in a city where people – as in much of the county – have found themselves cut off from real food and limited to the lifeless offerings of fast food chains and grocery stores stocked with processed food.
