註釋On May 14, 2008, Interior Secretary Dirk Kempthorne announced the listing of polar bears as threatened under the Endangered Species Act (ESA). The listing itself was praised by some environmentalists, other parties, who opposed the listing itself, argued that the science supporting listing was weak, but felt that the regulations mitigated some of the economic impacts of the listing.
