Scientists want us to eat insects, they say: "Eat insects for the sake of our health and our planet".

The practice of eating insects dates from prehistoric times and is well-documented in the early writings of most cultures. Even now, insects are viewed as both a staple and a delicacy by many. Insects can provide an important source of nutrition for people in many parts of the world. In regions where drought makes raising livestock or crops difficult, eating insects makes sense.
