Insect farming is growing rapidly as a sustainable protein source, raising welfare questions for species whose sentience status remains scientifically uncertain but cannot be dismissed.
Insect welfare sits at the frontier of animal welfare science and ethics. The precautionary principle suggests that given meaningful uncertainty about insect sentience, welfare considerations deserve application even in the absence of certainty. Practical welfare improvements include avoiding stocking densities that cause physical damage and ensuring slaughter methods are as rapid as possible. As production scales to the trillions of animals, even small per-individual welfare improvements aggregate to enormous moral significance. This is an area where early investment in welfare standards could prevent enormous future harm.
