On Sunday's show, we look at how to grow food sustainably. Is that permaculture? Or regenerative gardening? How about appropriate horticulture? We'll ask Robert Kourik, author of the just-released Sustainable Food Gardens: Myths and Solutions. Then Mike and Peggy dip into the grab bag of environmental news. Also, meteorologist Rick DiMaio is back and we'll talk about why it won't snow in Colarado but it will in Hawaii.
