The insect farming industry is growing rapidly as a sustainable protein source, yet the question of whether insects can suffer remains scientifically unresolved. Precautionary welfare approaches are gaining traction.
The moral status of insects is one of the most contested questions in animal welfare science. The precautionary principle suggests that uncertainty about insect sentience, combined with the enormous scale of insect farming, justifies investment in welfare research and potentially welfare standards. Key open questions include whether insect stress responses reflect subjective suffering or purely reflexive behavior. The welfare of trillions of individual animals may hang on how this science develops in coming years.
