Insect farming for protein is growing rapidly as a sustainable food source, and welfare considerations for farmed insects are being debated as the industry scales to billions of animals.
Insect farming welfare is a frontier issue where the scale of production intersects with deep scientific uncertainty about insect sentience. If insects lack subjective experience, welfare considerations are minimal. If some insects have even basic nociceptive consciousness, the scale of insect farming — trillions of animals — makes welfare improvement enormously impactful. The precautionary principle under uncertainty suggests developing and adopting the most humane feasible practices while research continues. Species selection, housing conditions, and harvest methods are all relevant variables even under uncertainty.
