Polar bears live in the ice and snow in the Arc­tic. Five coun­t­ries have polar bears: Den­mark, Nor­way, Rus­sia, the US and Ca­na­da. Polar bears have white fur. They are very big ani­mals. Male polar bears can be up to 3 m long and weigh 680 kg. Fe­ma­le polar bears can be up to 2.5 m long and weigh 250 kg. They live out­si­de, near the water. Polar bears eat other ani­mals like seals, wal­ru­ses and wha­les. They don’t eat every day, but they eat a lot when they have lots of food. Polar bears have to walk very slow­ly be­cau­se they are very big! They can run, but not very far. They can swim very well. They live for about 25 years. Polar bears are in trou­ble. People so­me­times kill polar bears for their fur. And the world is get­ting war­mer and the ice in the Arc­tic is mel­ting. Polar bears can’t hunt ani­mals wit­hout ice, so lots of polar bears are hungry.
