"....All five counties that have Polar Bears now give these giants of the north special protection. In 1973, the U.S.S.R, Norway, Greenland, Canada and the United States signed the Oslo Agreement. The agreement tried to do three main things: it hoped to preserve the rights of Eskimos to hunt Polar Bears; it proposed rules to protect cubs and females with cubs and it sought to outlaw the killing of Polar Bears form airplanes and large boats.
The five countries have since passed laws based on the agreement. Except for a few non-native permits issued in Canada, only Eskimos can now hunt Polar Bears. All countries have outlawed the use of airplanes and large boats from hunting the bears. Cubs and females with cubs are protected in all countries except the United States. Eskimos kill about one thousand Polar Bears each year. This is less that in years past."
And the bears, of course, continue to hunt and kill anyone or anything they want.
