Scientists and foodies have been searching for alternatives to traditional, animal protein-based food.  Land use, greenhouse gas emissions and obesity are touched on during this discussion about eating insects instead of beef, pork and poultry.

While many get squeamish at the idea, entomophagy — people eating insects — is a possible way to ensure a sustainable and secure food supply for the eight billion of us on the planet.

David Waltner-Toews, a veterinary epidemiologist from Kitchener, Ont., releases his latest book, Eat the Beetles! In it, Waltner-Toews criss-crosses the world, foraging in Japan, visiting insect farms across Canada and sampling insect-focused dishes in Australia and France – to make the case for greater insect consumption.
