Crickets: Protein Factories
These chirping insects efficiently convert plant waste into edible protein. They contain an impressive 60% protein by dry weight, far outpacing traditional livestock. A cricket colony produces 1kg of protein from just 2kg of feed. Their rapid reproduction in warm environments means quick scaling for growing colonies. The only downsides? They need secure enclosures to prevent escapes and soundproofing to reduce their constant chirping in confined Mars habitats.
