Humpback whales have recovered dramatically from the brink of extinction following commercial whaling bans. Their ongoing welfare faces threats from ship strikes, entanglement, and noise pollution.
Humpback whale recovery is one of conservation greatest success stories, but recovered populations now face a new suite of human-caused welfare threats. Ship strikes cause traumatic injuries including broken bones and internal hemorrhage that cause prolonged suffering before death. Entanglement in fishing gear — ropes that wrap around flippers, mouths, or bodies — causes chronic wounds, restricted movement, and slow death over months. Ocean noise pollution from shipping traffic disrupts the acoustic communication that whales depend on for mating, navigation, and mother-calf bonding. These are welfare harms experienced by individual sentient animals, and reducing them requires changes to shipping practices, fishing gear design, and noise regulation.
