Emeritus professor David Waltner-Toews, Population Medicine, was interviewed by CBC News May 10 about his new book, Eat the Beetles, and the possible popularity of eating insects among North American consumers. Waltner-Toews, who first grew interested in the idea through work with Veterinarians Without Borders (Canada), said East Asian consumers eat insects as a protein source that creates fewer greenhouse gas emissions than raising conventional livestock.
