Whales face multiple serious welfare threats from human activity including entanglement in fishing gear, vessel strikes, and chronic noise pollution that disrupts communication and navigation.
Entanglement causes profound and prolonged suffering. Whales dragging fishing gear may swim weakened for weeks or months, unable to feed, before drowning or dying of infection and exhaustion. Disentanglement operations require specialized teams and are dangerous for both rescuers and animals; many entangled whales are never found or cannot be safely accessed. Chronic noise pollution disrupts feeding, breeding, and mother-calf communication — a subtler but pervasive welfare harm affecting entire populations. Ship strikes cause blunt trauma, propeller injuries, and death that may be instantaneous or prolonged. Speed restrictions in critical whale habitat and ropeless fishing gear are the most evidence-backed interventions for reducing these harms.
