Silk production involves boiling silkworm pupae alive to preserve cocoon thread integrity — a practice affecting billions of individual animals whose capacity for suffering is uncertain but increasingly studied.
The welfare question for silkworms turns on unresolved questions about insect sentience and the specific capacity of Bombyx mori for pain experience. The precautionary principle suggests that given uncertainty and the enormous scale of the practice, some consideration is warranted. Ahimsa silk demonstrates that silk production without killing pupae is commercially viable, providing a welfare-consistent alternative for consumers who wish to exercise caution.
