The Arctic is home to over 21, 000 kinds of animals and plants. Two thirds of it is the Arctic Ocean. In winter, it is completely covered with sea ice. In summer, nearly 50 percent of these is ice.

It’s also home to about 4 million people, a group of whom are Inuit. Jim is an Inuit boy. At 6:30 am, he wakes up and gets ready to go to school in his fur coat. It keeps him warm in the freezing weather. Half an hour later, he gets to school on a ski or snowmobile. Some of his friends go by car instead. At 11 :30 am, it’s time for lunch. There’s fish and other meat in his lunchbox. He sometimes eats them uncooked. These foods give him enough energy. Besides local food, some people eat Western food. At 5:00 pm, the snow outside makes everything bright, so he wears snow goggles on his way back home, or his eyes may be hurt badly by the strong light. From December to March, the sun never rises. However, it always shines in the sky during the summer. At 10:00 pm, he goes to bed. Sometimes he stays in an ice house called igloo. It looks cold but it’s warm inside. Many local people live in houses made of wood.

The Inuit mainly make a living by hunting and fishing. Now, their life is greatly influenced by climate（气候）change. For example, many animals they hunt for food are disappearing. There is less food for the reindeer they keep, too. They face more terrible weather, such as snowstorms. Hunting becomes more dangerous. Hunters may accidentally fall into water if the ice becomes too thin. Actually, the temperature in the Arctic is 18℃ higher than it was 125 years ago. All Arctic ice may disappear during the summer in less than 100 years.
