Insect farming is growing rapidly as a sustainable protein source, but welfare considerations for insects are almost entirely absent from current practice. The ethical questions are both urgent and genuinely difficult.
Insect farming sits at the frontier of animal welfare thinking. The scale is enormous and growing rapidly; the evidence for insect sentience is genuinely uncertain; and the welfare implications of current practice are almost entirely unexamined. This is not a comfortable place to be from a welfare ethics standpoint. If insects can suffer even at low levels of probability, the sheer numbers involved - trillions annually - create an expected welfare cost that demands serious attention. The precautionary argument is not that we must assume insects definitely suffer, but that at this scale, uncertainty itself is a reason for investigation and caution.
