7. "Vulnerable" NOT "Endangered".

Vulnerable species

A Vulnerable species is one which has been categorised by the International Union for Conservation of Nature (IUCN) as likely to become Endangered unless the circumstances threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction. Vulnerable species are monitored and are becoming threatened. However, some species listed as "vulnerable" may in fact be quite abundant in captivity, examples being the blue poison dart frog.

More on Polar Bear and its status:
http://en.wikipedia.org/wiki/Polar_bear

The main threat to Polar Bears is NOT hunting, but Climate Change, even the Hunters know that (Through I do question if GOP Senators are that smart).

The list of the various status of animals is as follows:

Extinct (EX) – No known individuals remaining.
Extinct in the Wild (EW) – Known only to survive in captivity, or as a naturalized population outside its historic range.

Critically Endangered (CR) – Extremely high risk of extinction in the wild.
Endangered (EN) – High risk of extinction in the wild.
Vulnerable (VU) – High risk of endangerment in the wild.

Near Threatened (NT) – Likely to become endangered in the near future.
Least Concern (LC) – Lowest risk. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
Data Deficient (DD) – Not enough data to make an assessment of its risk of extinction.
Not Evaluated (NE) – Has not yet been evaluated against the criteria.

When discussing the IUCN Red List, the official term "threatened" is a grouping of three categories: Critically Endangered, Endangered, and Vulnerable.


The ICUN "Red List":

The Red list had a Statement that needs to be quoted:

Other population stress factors that may also operate to impact recruitment or survival include toxic contaminants, shipping, recreational viewing, oil and gas exploration and development. In addition to this comes a potential risk of over-harvest due to increased quotas, excessive quotas or no quotas in Canada and Greenland and poaching in Russia.

Yes, hunting is a problem, but Toxic contaminants, shipping, recreational viewing, oil and gas exploration and development are considered more serious problems.
