The polar bear is found in the Arctic Circle and some big land masses as far south as Newfoundland. While they are rare north of 88°, there is evidence that they range all the way across the Arctic, and as far south as James Bay in Canada. It is difficult to figure out a global population of polar bears as much of the range has been poorly studied; however, biologists calculate that there are about 20,000-25,000 polar bears worldwide.(www.hz123456.com)

Modern methods of  tracking polar bear populations have been employed only since the mid-1980s, and are expensive to perform consistently over a large area. In recent years some Inuit people in Nunavut have reported increases in bear sightings around human settlements, leading to a belief that populations are increasing. Scientists have responded by noting that hungry bears may be congregating around human settlements, leading to the illusion that populations are higher than they actually are. Of the nineteen recognized polar bear subpopulations, three are declining, six  are  stable, one is increasing, and nine lack enough data.

翻譯：北極熊通常生活在北極圈以及向南最遠(yuǎn)到紐芬蘭的一些大片的陸地上。雖然在北緯88°以北其較為罕見(jiàn)，但有證據(jù)表明，它們的活動(dòng)范圍甚至一直延伸到北極，向南則延伸到加拿大的詹姆斯灣。由于大部分有關(guān)其生活范圍的研究還很少，所以很難統(tǒng)計(jì)出全球北極熊的數(shù)量；不過(guò)，生物學(xué)家計(jì)算，全世界大約有2兩萬(wàn)到兩萬(wàn)五千頭北極熊。

翻譯：跟蹤北極熊種群的現(xiàn)代方法僅在20世紀(jì)80年代中期才被采用，而且，要在大范圍內(nèi)連續(xù)采用這種方法，其代價(jià)非常高昂。近年來(lái)，努納武特的一些因紐特人報(bào)告說(shuō)，在人類居住區(qū)周?chē)�看到北極熊的情況有所增加，這使人們認(rèn)為其數(shù)量在增加。而科學(xué)家們的解釋則是，有些北極熊由于饑餓可能會(huì)聚集在人類居住區(qū)周?chē)�（譯者注：由于氣候變暖，冰塊提前融化，導(dǎo)致北極熊覓食困難。），這就導(dǎo)致人們產(chǎn)生一種錯(cuò)覺(jué)，誤認(rèn)為北極熊的數(shù)量比其實(shí)有數(shù)量要多。實(shí)際上，當(dāng)前，其數(shù)量在19個(gè)公認(rèn)的北極熊亞種群中，3個(gè)在下降，6個(gè)較穩(wěn)定，1個(gè)在增加，9個(gè)缺乏足夠的數(shù)據(jù)。
