Insect farming is expanding rapidly as a sustainable protein source, but welfare considerations under moral uncertainty require precautionary approaches to minimize potential suffering at massive scale.
Insect farming welfare operates under genuine scientific uncertainty about whether insects have welfare-relevant subjective experiences. The moral calculus is complicated by the scale - any precautionary welfare obligation applied to trillions of insects would have enormous aggregate implications even if individual welfare probability is low. The precautionary principle suggests applying humane treatment even under uncertainty when the cost is low, and several insect welfare research programs are investigating both sentience evidence and practical welfare interventions. The long-term trajectory of insect farming welfare will depend on how this uncertainty resolves and what regulatory frameworks emerge.
