Silk production requires killing silkworm pupae inside their cocoons — raising welfare questions about the ethics of insect killing at industrial scale.
Silk industry welfare sits at the extreme end of insect welfare uncertainty. The number of animals killed — billions annually — is extraordinary. The welfare significance of each killing depends entirely on one's assessment of silkworm sentience, which is genuinely uncertain. The neurological architecture of silkworms — a simple ganglion-based system — does not support sophisticated information processing comparable to vertebrates. But genuine uncertainty remains. Ahimsa silk provides an alternative that avoids killing at the cost of different fibre properties. Synthetic alternatives eliminate both the uncertainty and the environmental footprint. The scale of silkworm killing makes this a welfare question worth taking seriously even under significant uncertainty.
