Since 1900, there have been 250 documented arrivals of polar bears to Iceland, with a particularly large number (at least 27) arriving during the winter of 1917-1918. Recent arrivals include two bears in 2008, one in 2010, and one in 2011. While some people argue for non-lethal removal of polar bears from populated areas, Icelandic law allows for killing bears if they pose a threat to people or livestock. A few of the polar bears that have been killed in Iceland have been stuffed and preserved in museums to educate people about these Arctic animals.
