“You see I'm an artist. Gardening is my graffiti, I grow my art.”
Depressed at the lack of availability of real food in South Central LA ("The drive through's are killing more people than the drive by's"), Ron Finley started growing an Urban Garden upon the public waste land beside his house. Having overcome opposition from the city authorities (yes really) he's now aiming to start a revolution on the thousands of acres of Los Angles' waste land, changing peoples perception of food along the way. Very inspiring project!
