This week, we're looking at the environmental impact of foods we eat, and others that we should. We'll speak to Daniella Martin, host of the insect cooking/travel show "Girl Meets Bug," about her book "Edible: An Adventure into the World of Eating Insects and the Last Great Hope to Save the Planet." And we'll talk about the environmental effects of salmon farming with Peter Bridson, Aquaculture Research Manager for the Seafood Watch program at the Monterey Bay Aquarium.
