Insects can be fed on all kinds of waste, including shit! I linked to a UN report that gives some details.
Agree about fish farming. The fish have miserable lives, their meat is poor quality due to those miserable lives, and something like a third of the entire worldwide catch goes to make fishmeal to be fed to farmed fish. Most of that fishmeal is perfectly good to be eaten directly by us. Fishmeal is even fed to basically vegetarian fish like tilapia, which is the height of folly. We really do do some fucking stupid things.
