Whaling controversy

Whale conservation is the international environmental and ethical debate over whale hunting. The conservation and anti-whaling debate has focused on issues of sustainability as well as ownership and national sovereignty. Also raised in conservation efforts is the question of cetacean intelligence, the level of suffering which the animals undergo when caught and killed, and the importance that the mammals play in the ecosystem and a healthy marine environment.

The International Whaling Commission (IWC) 1986 moratorium on commercial whaling, the value of lethal sampling of whales for scientific research in order to establish catch quotas has also been debated. The value of whaling to fisheries as a method of controlling whales' perceived negative impact on fish stocks is another point of debate.

Prior to the setting up of the IWC in 1946, unregulated whaling had depleted a number of whale populations to a significant extent, and several whales species were severely endangered. The International Union for Conservation of Nature (IUCN) notes that the Atlantic population of gray whales was made extinct around the turn of the eighteenth century. Examination of remains found in England and Sweden found evidence of a separate Atlantic population of gray whales existing up until 1675. Radiocarbon dating of subfossil remains has confirmed this, with whaling the possible cause. Whaling and other threats have led to at least five of the 13 great whales being listed as endangered. A past ban which was implemented around the 1960s has helped some of these species of whale to recover. According to IUCN's Cetacean Specialist Group (CSG), "Several populations of southern right whales, humpbacks in many areas, grey whales in the eastern North Pacific, and blue whales in both the eastern North Pacific and central North Atlantic have begun to show signs of recovery." Populations of many other whales species are also increasing.
