  1. Polar Bears go out on to sea ice to catch seals. Global warming is melting the sea ice.
  2. Polar bears live on the ice to live and catch food that is on land. Well, the sun is melting more and more of the ice, so there's no ice for teh bears to live on.
  3. Because of global warming the sun is increasing in temperature so it is melting the ice in the Artic. With the ice gone, it means the bears have less chance of catching prey [food] because the animals they eat live on land. They usually eat seals but because they live in the sea too, they can survive. Whilst the Polar Bear will just die because of the lack of food.
  4. polar bears swim in the water alot, but they depend on the ice on which to live. The global warming is melting the ice caps, so they have to swim out to go find other 1's. Sadly, they can not find other 1's cuz there are very little left. So they just keep swimming until they are exhausted and give up. Sad, isn't it??
  5. Global warming is heat that stays on earth. Too much can cause the melting of ice. Polar bears go in the water and stand on the ice. Well there's too much water not enough snow/ice.
  6. polar Bears live on the North pole and the noth pole dos not have land ,like the south pole , it is ice floating on the water now the ice is melting and in the end the polar bears will be swimming around with nowhere to call a home they will have to go to Alaska and get used to eating what is there ,problem is they like eating people when they cant find seals or fish
  7. The National Wildlife Federation's website has some good information http://www.nwf.org/polarbearsandglobalwarming/ Polar bears are exquisitely adapted for living and hunting on sea ice. They can swim steadily for many hours in near freezing water with their special adaptations of partially-webbed feet and water-repellent coats. However, global warming pollution is melting the Arctic sea ice at an alarming rate. According to the National Snow and Ice Data Center at the University of Colorado at Boulder, sea ice is declining at a rate of more than 23,000 square miles per year (or nearly nine percent per decade!). Polar bears are literally drowning from global warming, unable to swim the increasingly longer distances between land and receding sea ice. They depend on this sea ice to hunt their primary food source--seals. With ice forming later in the fall and breaking up sooner in the spring, the time period bears can forage for food is shrinking every year. A recent study by the U.S. Geological Survey's Alaska Science Center discovered a "very dramatic" change in cub survival and estimated that only about 43 percent of the polar bear cubs in Alaska' Beaufort Sea are surviving their first year as a result of shrinking ice habitat. Cub survival is down from about 65 percent survival measured in the late 1980s and early 1990s.
