Global warming is causing the thinning of sea ice, the polar ice caps are shrinking and the hunting grounds of polar bears are melting under their very feet. That is the essence of the problem facing these magnificent creatures. A recent report on global warming by over 300 scientists predict that by the end of this century the artic ice cap could shrink by half, or even disappear totally. If this happens,  it would cause the estimated population of 20,000-25,000 polar bears and countless other artic species to go extinct. Scientists, for the first time ever, have documented multiple deaths of polar bears off Alaska, where they more than likely drowning by being forced to swim long distances in the ocean. Prior to 2004, the spotting of a lone bear swimming in the ocean far from ice only happened about once every two years. A rare event. But not any more. The rules of the game have changed, the ice caps are melting and this is forcing these great creatures to swim farther in search of food, far beyond their normal range, and as a result they are dying. Polar bears can swim long distances but have evolved to mainly swim just between sheets of ice. In September of 2004, researchers counted 10 bears swimming as far as 60 miles offshore.

Another just as sinister a threat to these great animals is pollution from chemicals used in flame retardants and pesticides. Originating largely in the United States these chemicals are building up in their bodies and having toxic effects. The flame retardants, polybrominated diphenyls, or PBDEs, are one of the newest additions to hundreds of industrial compounds and pesticides carried to the Arctic by northbound winds and ocean currents. Accumulating in the fatty tissues of animals, many chemicals grow more concentrated as larger creatures eat smaller ones, turning the Arctic's top predators and native people into some of the most contaminated living organisms on Earth.

In polar bears, the effects are unknown. But in tests on laboratory animals, PBDEs disrupted thyroid and sex hormones and damaged developing brains, impairing motor skills and mental abilities, including memory and learning. Scientists say that other industrial chemicals with properties similar to PBDEs are already weakening the bears' immune systems, altering their bone structure, skewing their sex hormones and perhaps even causing small numbers of hermaphroditic bears.

IUCN - The World Conservation Union, through its Species Survival Commission (SSC) has for four decades been assessing the conservation status of species, subspecies, varieties and even selected subpopulations on a global scale in order to highlight species threatened with extinction, and therefore promote their conservation.
