"other countries embraced insects as food long ago, with folks in Latin America and Asia regularly snacking on locusts and even scorpions. And they may be onto something: Bugs are not only high in protein — they're low in fat, carry extremely low carbon footprints, and are cheap to produce. They possess all the traits necessary to become the next sustainable superfood.
Meat's impact on the environment is well-documented, with livestock production creating about 18 percent of the globe's greenhouse gas emissions. Even fruits and veggies typically take a lot of resources — like water, fertilizers, pesticides and herbicides, and mechanized farm equipment — to produce. Bugs are naturally plentiful, and raising them as a food source would only require minimal resources. Plus, some insects like locusts are notorious agricultural pests. Eating them would reduce the need for environmentally degrading chemical pesticides.
Not only do bugs tread lightly (or in some cases, fly lightly), they're a cheap and nutritious food source. Bugs boast high amounts of protein and low amounts of fat. Perhaps America's obesity epidemic wouldn't be at such massive proportions (literally) if more folks took up entomophagy."
