Ireland’s largest bookmaker Paddy Power is taking bets on the estimated global polar bear population on 31 December 2011 according to the world's largest independent conservation organization, the WWF.
WWF runs schemes  which enable people to adopt and sponsor polar bears, to help in their preservation.
The current WWF estimate places the polar bear population between 20,000 and 25,000 however Paddy Power’s odds predict a sharp decline in their population over the next two years and are offering odds of 13/8 that the number dips between 15,000 to 20,000.
The bookie is also offering odds on the number of critically endangered species that will appear on the IUCN Red List of Threatened Species in 2010 with between 3501 and 4000 the 11/8 favourite.
Paddy Power said “With global warming now generally agreed to be the most significant threat to the polar bear we predict that their population will move in only one direction. Punters seem to share this view as we are yet to take a single bet on the polar bear population increasing”
