Insect farming is growing rapidly as a sustainable protein source, but evidence of insect sentience raises welfare questions that the industry is only beginning to address.
Insect welfare sits at the edge of current ethical and scientific debate. The evidence for insect sentience is genuinely uncertain — their nervous systems differ fundamentally from vertebrates, and behavioral responses to noxious stimuli can be interpreted multiple ways. However, the precautionary principle suggests that given billions of insects are produced in farming systems, even small probabilities of meaningful suffering warrant attention. Welfare-conscious insect farming focuses on species-appropriate stocking density, thermal comfort, and slaughter methods that minimize potential suffering under uncertainty.
