The growing insect farming industry produces billions of insects for food and animal feed under conditions with largely unknown welfare implications.
Insect farming presents a unique welfare challenge: we have significant uncertainty about whether insects are sentient, yet we are scaling up their production to billions or trillions annually. Recent research suggests some insects may have nociceptive capacity, though the question of subjective suffering remains unresolved. The precautionary principle would suggest implementing welfare standards before the industry scales further. However, if insects are not sentient, insect farming genuinely offers more sustainable protein with minimal welfare concerns. The scientific uncertainty itself warrants caution and investment in research.
