Commercial beekeeping exposes honey bee colonies to welfare stresses including pesticide exposure, habitat loss, transport stress, and pathogen pressure at massive scale.
Whether bees are sentient in a morally relevant way is debated, but they show nociceptive responses, stress hormones, and pessimistic cognitive biases after negative experiences. At the scale of commercial apiculture — billions of individual insects — welfare considerations are significant even under uncertainty. Colony transport, disease management, pesticide exposure, and queen manipulation all represent welfare considerations for an ecologically critical species.
