Insect farming is growing rapidly as a sustainable protein source, but the welfare implications of farming potentially sentient invertebrates deserves careful consideration.
Insect welfare sits at the frontier of animal welfare ethics. The evidence for insect sentience is weaker than for vertebrates, but not zero — and given the enormous numbers involved, even small probabilities of morally relevant experience have significant aggregate implications. Responsible insect farming applies precautionary standards: optimising rearing conditions for species-specific needs, using rapid slaughter methods, and investing in research to better understand insect capacity for suffering. Consumer demand for insect-based foods should be accompanied by demand for welfare standards.
