Insect farming could reduce vertebrate animal use but raises welfare questions about the sentience of billions of insects processed annually.
Insect farming is often presented as a welfare improvement over vertebrate farming because insects likely have more limited sentience. However, the enormous numbers involved and growing evidence of insect nociception suggest a precautionary approach is warranted. Investment in insect welfare research, humane slaughter methods for insects, and monitoring of farming conditions all reflect appropriate ethical seriousness about the question.
