Click here to read the USFWS`s proposed rule to list polar bears as threatened throughout its range. For Molnár, however, the question arises: «Can polar bears adapt to all this?» Killing endangered or rare animals to save them is wrong from an ethical, economic, biological and conservation point of view. The idea behind conservation hunting has no place in modern conservation. It is a relic of pioneering safari organizations founded by big game hunters. «Modern trophy hunting» is a new approach to wildlife harvesting, where tourists «shoot» animals with cameras instead of guns. The trophies they take home are images for souvenirs, impressions or social media – not dead animals. This modern business opportunity benefits from the fact that the same animal can be sold more than once and to more than one person. In the long run, this approach can benefit both polar bears and local institutions. Young argued, «I`m an environmentalist, but not a fool. And it has nothing to do with the future slaughter of polar bears or anything else. The growth rate of polar bears is biologically low due to poor young survival, late maturity, small litter size and long weaning period.
Assuming unrealistic survival rates of 95% for all age groups, one pregnancy every three years for all females over five years of age, and two cubs in all litters, the theoretical maximum growth rate of polar bear populations is only 10%. However, this high growth rate is not possible in wild polar bear populations and the maximum growth rate in the wild is about 6.5%. Instead, assuming average observed survival rates, a litter of 1.64 and a litter interval of 3.6 years, the average growth rate of polar bears is closer to 2.0%. Countries around the world agree that polar bears are in trouble: they are considered threatened in the United States, of particular concern in Canada and endangered internationally. But in much of their icy habitat, it`s perfectly legal to take a gun and shoot one. Oil and gas development affects polar bears in a variety of ways, polluting the ocean with hydrocarbons, reducing and disturbing their habitat with related infrastructure, and increasing vessel traffic. Pollution from both distance and proximity can lead to serious health problems and even the death of the polar bear. Because polar bears depend on sea ice to hunt, some scientists say global warming is their biggest threat. Climate change and sea ice loss have dominated polar bear conservation discussions in recent years.
While a warmer climate may largely determine the future distribution of polar bears, the vast majority of population declines over the past 30 years are due to unsustainable hunting. At least for the next 10 to 15 years, hunting will likely continue to play an important role in determining polar bear population trends. Eastern Siberia and the Chukotka Peninsula are villages so large that they must be included. Without local hunters and community organizations, «there is no way to control the number of bears killed,» he said. With instructors and taggers in the villages and scientific support from the North Slope Borough Department of Wildlife, they have set a conservative quota in recent years. Recently, they proposed reducing their subsistence harvest from a total of 80 to a total of 70 polar bears per year – 35 for each country. Several threats could lead to the extinction of polar bears by 2100. The main of these threats are climate change, oil spills, habitat loss and disturbance through development and tourism, pollution, hunting and self-defense, cannibalism, and the capture of polar bears for public display in zoos.
Legislation has been created to address these threats at all levels of government in the five Arctic states. Many Alaska natives also support the border because it opens the door for their cousins across the Bering Strait to hunt legally for the first time in 65 years, he said. The fur tag acts as a certificate for legal trade and must be applied to the skin at all times. Polar bear pelts are sent to fur auctions that attract international buyers. Once a polar bear skin has passed through an auction house and sold to an international buyer, it is ready to be exported. A CITES export permit must be issued before a polar bear hide can be legally exported. Different regulations apply to the import of polar bear pelts depending on the importing country. In the United States and Mexico, the importation of polar bear skins and body parts is illegal, even if the parties have validated export permits. Fur traders often assure polar bear fur buyers that the hunt is limited and sustainable, and that the bear was captured during the subsistence hunt. This is not always true; Thus, some buyers buy polar bear skins without knowing the real circumstances and challenges of hunted bears. Trophy hunting in Svalbard was not as popular as in Alaska at the same time, but bears were still hunted relentlessly by sealers (22,018 bears), trappers (6,051 bears) and weather station workers (1,459 bears) from 1871 to 1973. In 1973, the Norwegian government banned polar bear hunting in Svalbard and trophy hunters had to find new areas for their activity.
Trophy hunting of polar bears has also been banned in Russia since 1956, in the United States since 1972 and in Greenland in 1973. Thus, the only remaining area for polar bear trophy hunting was the Canadian Arctic. Liodden sees Svalbard, a group of islands between Norway and the North Pole, as a model for the future.
