are you concerned about the environmental footprint of your diet but not ready to give up all animal protein? Then eat bugs. People all over the world relish insects. Why do we have such a yuck response? Some bugs are loaded with nutrients and can be easily "farmed" with a small footprint.
Part of the barrier is that people in the US aren't used to looking their food in the eye. How many people would give up meat if they had to look at the sweet cow's face? So insectivores are getting smart. They're mixing bugs into products that look familiar (energy bars, flour). This article showcases a number of tasty products. Try one and then let us know how it tasted.
