Polar+Bears

Polar Bears are a type of bear that likes cold weather.
===They like it where the weather will be cold and everything will always be cold. Global warming has been taking a big toll on polar bears if we don't help them then they will die. ===

 * Body.** A polar bear has a long body and neck. Its head appears long and narrow with short, furry ears. Sharp teeth and curved claws help polar bears to catch their prey. From nose to tail, adult male polar bears measure from 7.5 to 8.5 feet long. Some weigh more than 1,300 pounds. Most adult female polar bears are about 6.5 feet long and weigh 330 to 550 pounds.


 * Food.** Polar bears feed mainly on seals—usually a small species of seal called the ringed seal and a larger species called the bearded seal. In the spring, polar bears hunt young ringed seals by killing them at their dens. Later, seals are hunted at holes in the ice when they come up for air. After the ice breaks up, polar bears may surprise seals resting on floating ice by swimming up and pouncing on them. Polar bears will eat many other things, including berries and grasses, birds’ eggs, ducks, geese, lemmings, reindeer, seaweed, walrus, certain whales, and sometimes other polar bears.


 * Polar bears and people.** Polar bears don't usually kill and hurt people. People threaten the survival of polar bears through pollution and hunting. Global warming can also reduce the ice on which the bears live and hunt, threatening their survival (see [|Global warming]). Laws protect polar bears in all places where they live.
