POLAR BEAR SCARE

...

"Warnings about the future of the polar bear are often contrasted with the fact that worldwide population estimates have increased over the past 50 years and are relatively stable today.[200][201]

"Some estimates of the global population are around 5,000 to 10,000 in the early 1970s;[202] other estimates were 20,000 to 40,000 during the 1980s.[48][62]

"Current estimates put the global population at between 20,000 and 25,000[39] or 22,000 and 31,000.[2]

...

"There are several reasons for the apparent discordance between past and projected population trends: estimates from the 1950s and 1960s were based on stories from explorers and hunters rather than on scientific surveys.[203][204][205][206] 

"Second, controls of harvesting were introduced that allowed this previously overhunted species to recover.[203] 

"Third, the recent effects of climate change have affected sea ice abundance in different areas to varying degrees.[203]

"Debate over the listing of the polar bear under endangered species legislation has put conservation groups and Canada's Inuit at opposing positions;[43] the Nunavut government and many northern residents have condemned the U.S. initiative to list the polar bear under the Endangered Species Act.[207][208] 

"Many Inuit believe the polar bear population is increasing, and restrictions on commercial sport-hunting are likely to lead to a loss of income to their communities.[43][209]"
