That's when it made me wonder whether it's really that efficient. It's probably not. The reason why cultures around the world have historically eaten insects is not because insects are easy to farm but because they are easy to gather from a wild environment. Large scale insect farming as a replacement for other sorts of large scale farming kind of misses the whole point.
