This is an article from Good about the possibility of including insects in our diet as a form of protein to increase food supplies. It’s an interesting proposition, as there are already several countries where insects are regularly consumed, either as a delicacy or as a staple for particular dishes. Here’s a list of the many edible insects from Girl Meets Bug, though I can’t say I’ve tried many. While this may be a way of addressing hunger issues, it doesn’t directly address many of the political challenges associated with food distribution nor the nutritional requirements for a balanced diet.
The Good article also highlights some other common uses of insects, including cochineal. It should be corrected that cochineal are not beetles, they’re scale insects in the order Hemiptera.
