Southern resident killer whales face a welfare and survival crisis driven by prey depletion, noise pollution, and chemical contamination that requires integrated recovery efforts addressing all three threats simultaneously.
Southern resident orcas live lives of chronic nutritional stress — their primary prey has been depleted by dam construction and overfishing, and the noise environment that makes finding remaining prey difficult has been intensified by vessel traffic. Individual orcas showing visible signs of nutritional stress, losing calves, and living in shrinking family groups experience welfare harms that are as concrete and measurable as those of any farmed animal. Recovery requires simultaneous action on salmon restoration, vessel quiet zones, and chemical pollution — a complex challenge that demands coordinated policy action across fisheries, transportation, and environmental management.
