The destruction of its habitat on the Arctic ice by global warming threatens the bear's survival as a species; it may become extinct within the century. Signs of this have already been observed at the southern edges of its range.http://www.biologicaldiversity.org/swcbd/species/polarbear/index.html There have been no proposals to date to transplant the species to some other environment, such as Antarctica.
