Transcript of Polar Bears

Polar Bears Polar bear cubs are usually born in pairs, however there are three cubs and possibly only one cub. It is a rare occasion that there are four cubs. They are born in the months of December or early January in the Svalbard islands; a group of islands in the Arctic Oceans Islands. A traditional denning area for polar bears called Bogan Valley. These dens are found just below the ridge of Retzuis Mountain, which is in Svalbard.

Polar Bear Cubs Last year, the Secretary of the Interior, Dirk Kempthorne, proposed adding Polar Bears to the threatened species list. The decision will be made whether or not to include Polar Bears on the list in January of 2008. Polar bear deaths due to global warming are of increasing concern, and new studies speculate that Polar Bears may face possible extinction. Most dangerous is the fact that as global warming increases, Polar Bears will have a difficult time finding food. In fact, numerous polar bears are feeling the effects of a shortage of food and are facing starvation.

Global Warming There are an estimated 20,000 Polar Bears in the wild and they depend upon the arctic weather for their livelihood. Today, there are many accounts of Polar Bear, global warming deaths attributed to drowning. The Polar Bear is doomed if something isn’t done to reverse the dangers of global warming. Polar Bears depend upon the natural habitat of the Arctic, however global warming has contributed to the growing loss of Arctic Ice. In fact, polar bears have been photographed clinging to tiny ice formations as their natural environment simply melts away, leaving them at the mercy of a climate that they cannot survive in. One of the best ways to prevent the affects of global warming on polar bears is to stop (CO2) Carbon Dioxide emissions. Everyone can do their part to cut down on these terrible wastes and help save the planet. You can find ways to cut back on (CO2) Carbon Dioxide emissions from recycling and reusing products to using energy efficient appliances. The only way to see a halt in global warming is for everyone to make a change, no matter how small those changes may seem. It is everyone’s responsibility to do his or her part and give Polar Bears a chance. How to prevent the affects of global warming on polar bears? It may be the latest evidence of global warming: Polar bears are drowning.

Scientists for the first time have documented multiple deaths of polar bears off Alaska, where they likely drowned after swimming long distances in the ocean amid the melting of the Arctic ice shelf. The bears spend most of their time hunting and raising their young on ice floes.

In a quarter-century of aerial surveys of the Alaskan coastline before 2004, researchers from the U.S. Minerals Management Service said they typically spotted a lone polar bear swimming in the ocean far from ice about once every two years. Polar-bear drownings were so rare that they have never been documented in the surveys.

But in September 2004, when the polar ice cap had retreated a record 160 miles north of the northern coast of Alaska, researchers counted 10 polar bears swimming as far as 60 miles offshore. Polar bears can swim long distances but have evolved to mainly swim between sheets of ice, scientists say.
Is Global Warming Killing the Polar Bears? For years our governments have been pretending Global Warming doesn't exist. This is due to money and influence from certain coal and oil companies. Only recently have we seen a change in this and it is because of people like you. People like you have started to stop Climate Change on a local level in their communities and they have demanded that their governments take this seriously.
SAVE THE POLAR BEARS Polar Bears and Sea Ice

Scientists estimate that 20,000 to 25,000 polar bears live throughout the Northern Hemisphere in areas that are covered by sea ice for extensive periods.

Polar bears eat mostly seals and other fatty marine mammals that they hunt from the ice.

In some places—like the southern end of polar bear range in Canada's Hudson Bay—the sea ice melts in the summer. The bears then come onto land, where they have insufficient food until the sea ice refreezes in the fall.

Those bears, USGS's Amstrup said, may be the first to die off. As the sea ice melts sooner each summer, the bears will be forced to come ashore earlier and face food shortages before they have stored enough fat to last through the season

That's a position critics dispute after the 10.8-million gallon Exxon Valdez oil spill in 1989, a 200,000-gallon North Slope pipeline spill in March 2006, and the state-funded killing of more than 1,000 wolves and hundreds of black bears since 2003 to increase moose and caribou populations.

Polar bears are regulated by the federal government like whales and seals. They spend most of their lives on frozen ocean water, where their main prey, ringed seals, give birth to pups in lairs. Warming of Arctic waters has significantly diminished the sea ice.
