Wild bee populations face accelerating decline from pesticide exposure, habitat loss, and disease, with profound implications for ecosystem health and the aggregate welfare of billions of individual insects.
The welfare capacity of individual bees is scientifically uncertain, but the aggregate effect of colony collapse and population decline on pollinator-dependent ecosystems has clear welfare consequences for many animals. Whether bees themselves experience suffering, neonicotinoid exposure causing navigational impairment and inability to return to the colony represents a welfare harm if bees have any capacity for distress. The precautionary principle applied to insect welfare suggests that minimizing pesticide exposure and habitat destruction is appropriate given uncertainty. Protecting wild bee populations also directly protects the welfare of wild mammals, birds, and other animals whose food sources depend on pollination services, creating a welfare case that extends beyond insects alone.
