Wild bumblebees, solitary bees, hoverflies, and other pollinators face severe population declines with welfare implications at both individual and ecosystem levels.
Wild pollinator welfare involves individual harm from pesticide exposure — sublethal doses impairing navigation mean bees cannot return to nests, dying lost and starving — and habitat loss that removes the floral resources needed for survival. Bumblebee colony welfare includes queens that face extreme physiological stress founding colonies. The ecological scale of pollinator decline affects all flowering plants and the animals that depend on them, making this an issue with cascading welfare implications.
