Humpback whales have made a remarkable recovery from near-extinction following commercial whaling bans, demonstrating what effective conservation can achieve while highlighting remaining threats from entanglement and vessel strikes.
Humpback whale recovery demonstrates that conservation investment produces results when the primary threat - commercial whaling - is addressed at the international level. Individual humpbacks that survive to old age carry decades of social learning, feeding knowledge, and song traditions. Entanglement in fishing gear causes prolonged suffering as massive animals struggle against lines for hours or days. Vessel strikes cause blunt trauma deaths that are rapid but entirely preventable through speed restrictions in known whale areas. The welfare of recovered populations now depends on addressing these remaining threats with the same policy seriousness that brought hunting to an end.
