Farmland pollinators face welfare-relevant declines from pesticide use, habitat loss, and changing agricultural practice.
Pollinator welfare encompasses both individual suffering from pesticide toxicity and population-level collapse from habitat loss. Sublethal neonicotinoid exposure impairs navigation, learning, and reproduction in bumblebees reducing colony survival. Loss of flower-rich habitat means foraging bees travel further and return with lower nutritional quality food. Emerging evidence of pain experience in bees suggests that mass pesticide exposure constitutes a welfare harm at an enormous scale.
