Insect farming is growing rapidly as a sustainable protein source, but questions remain about whether insects can suffer and what welfare standards should apply to the billions farmed each year.
The scientific debate about insect sentience is genuinely unresolved. While insects lack the brain structures associated with vertebrate pain processing, some show avoidance learning and stress responses. The sheer scale of insect farming means even small probabilities of suffering represent enormous aggregate concern. Research into humane slaughter methods, stocking densities, and environmental conditions is being conducted, and the field warrants serious welfare attention.
