there are many places in the world were insects are considered a natural supplement or even a delicacy.
In T2K old prejudices against this source of protein would have to be dropped many places .
eating cockroaches and even breeding them in farms as livestock would be a necessity .It is absolutely viable as a food source .the habitat needs to be sealed off -of course - and heated to a certain temperature. As for feed -anything goes .The more energy rich the better the "heads" will fatten , but the good things about roaches is that many kinds are omnivores-meaning that refuse,potato peels,fresh cut grass and those dead people we discussed burying earlier will all be eligible for feed.
The roaches are ground up to flour after -so the disgusting bit can be tones down a bit -until you serve it up as porridge
Seriously -people are trying to save the planet and make a profit from marketing insects as food.We already eat about 1 kg or 2 pounds every year in fragments in the ketchup,in the bread ,in the condiments,the jam,the sodapop -in everything we have pretty much .
For the most part its healthy .
Roaches need a good soak in acidic fluids like vinegar or orangejuice before they are roasted dry and then ground up .very protein rich .
