An endangered species is a population of an organism which is at risk of becoming extinct because it is either few in number, or threatened by changing environmental or predation parameters. An endangered species is usually a taxonomic species, but may be another evolutionary significant unit. The World Conservation Union (IUCN) has calculated the percentage of endangered species as 40 percent of all organisms based on the sample of species that have been evaluated through 2006.[2] (Note: the IUCN groups all threatened species for their summary purposes.) Many nations have laws offering protection to these species: for example, forbidding hunting, restricting land development or creating preserves. Only a few of the many species at risk of extinction actually make it to the lists and obtain legal protection. Many more species become extinct, or potentially will become extinct, without gaining public notice.
The conservation status of a species is an indicator of the likelihood of that endangered species not living. Many factors are taken into account when assessing the conservation status of a species; not simply the number remaining, but the overall increase or decrease in the population over time, breeding success rates, known threats, and so on. The IUCN Red List is the best known conservation status listing.
Internationally, 189 countries have signed an accord agreeing to create Biodiversity Action Plans to protect endangered and other threatened species. In the U.S. this plan is usually called a species Recovery Plan
The IUCN Red List of Threatened Species uses the term endangered species as a specific category of imperilment, rather than as a general term. Under the IUCN Categories and Criteria, endangered species is between critically endangered and vulnerable. Also critically endangered species may also be counted as endangered species and fill all the criteria
The more general term used by the IUCN for species at risk of extinction is threatened species, which also includes the less-at-risk category of vulnerable species together with endangered and critically endangered.
IUCN categories include:
Extinct: the last remaining member of the species had died, or is presumed beyond reasonable doubt to have died. Examples: Thylacine, Dodo, Passenger Pigeon
Extinct in the wild: captive individuals survive, but there is no free-living, natural population. Examples: Alagoas Curassow
Critically endangered: faces an extremely high risk of extinction in the immediate future. Examples: Ivory-billed Woodpecker, Arakan Forest Turtle, Javan Rhino
Endangered: faces a very high risk of extinction in the near future. Examples: Cheetah, Blue Whale, Snow Leopard, African Wild Dog
Vulnerable: faces a high risk of extinction in the medium-term. Examples: Gaur, Lion
Least Concern: no immediate threat to the survival of the species. Examples: Norway Rat, Nootka Cypress Hawaiian Hawk

First, I didn't know Polar Bears were American. Perhaps they can vote, which would be very helpful because politicians would want to keep them alive.
As much as we like the cute fellows, they are really vicious predators. I don't see anyone staying up all night crying over sabre-tooth tigers, so why should I cry over polar bears?

Due to Global Warming? The animation in An Inconvenient Truth was hilarious. The polar bear was swimming and couldn't find an ice chunk solid enough to support him. Most people in my class were sad and shocked. Me and my friend laughed our asses off.
