Whole Foods Market on Wednesday began a ratings program for fruits, vegetables and flowers aimed at giving consumers more information about pesticide and water use, the treatment of farmworkers and waste management, and other issues surrounding the food they eat. The upscale grocery chain will rate the produce of suppliers electing to participate in the program, Responsibly Grown, as "good," "better," or "best," depending on, for example, how they handle plastic waste in their operations and whether they provide conservation areas to foster bees, butterflies and other pollinators.
