Many foodies and sustainability activists don’t like genetically-modified organisms, or GMOs.  But are their concerns a matter of style or substance?  A recent Zócalo/UCLA panel, held at MOCA Grand Avenue in downtown L.A. and moderated by KCRW Good Food host Evan Kleiman, explored concerns about GMO products. UCLA molecular biologist Bob Goldberg joined longtime Los Angeles Times food editor Russ Parsons and Edward Parson, a co-director of the Emmett Institute on Climate Change and the Environment at UCLA, in a wide-ranging discussion that touched on food safety, environmental regulation, corporate monopolies and what foods the panelists like to cook, buy, and eat.
