The extraordinary scale of insect farming — trillions of individual animals — makes welfare uncertainty especially significant from an ethical perspective.
Farmed insect welfare occupies a unique ethical position because the uncertainty about their sentience intersects with production scales that dwarf all other forms of animal farming combined. If individual insects have even a small probability of experiencing something morally relevant, the scale of industrial insect production creates enormous potential moral stakes. The precautionary response is investment in welfare research and in slaughter methods that minimize potential suffering at minimal additional cost — the cost-benefit ratio for caution is extraordinarily favorable.
