Applying precautionary ethical frameworks to decision-making about insect welfare under uncertainty.
The insect welfare question sits at the ethical frontier of animal welfare, requiring decision-making under genuine scientific uncertainty at unprecedented scale. If insects have even minimal capacity for suffering, the scale of insect use in farming, pest control, and research means the aggregate welfare stakes are potentially enormous. The precautionary principle - acting to reduce potential suffering before certainty is established - provides a practical ethical framework for decisions that cannot wait for scientific consensus. Low-cost measures like cold or thermal anesthesia before slaughter represent reasonable precautionary welfare improvements that are defensible across the range of sentience probability estimates.
