We often think the Arctic(北极)only has snow and ice. But in fact,
it
11
has far more than that!
The Arctic is on top of Earth. The Arctic Ocean
makes
12
up two-thirds of the Arctic, while one-third is made up of land in eight countries,
including
13
Russia, Canada, Finland and the US.
The Arctic lands are quite different
from
14
each other. There are forests, green tundra(冻原)and glaciers(冰川). Many plants are growing there. Though the natural
condition
15
is bad, the plants can grow in very cold temperatures.
The polar bear is the most famous Arctic animal. But in fact, the Arctic is home to more than 21,000 species of plants and animals. There are whales, Arctic foxes, walruses and many more. But
recently
16
, their place to live is smaller because the temperature is becoming higher and the ice is losing. So it is necessary for people to
protect
17
these animals.
You might think that the Arctic is too cold for people to live in.
But
18
surprisingly, there are about 9 million people living there. That's the same
population
19
as the city of Xuzhou in Jiangsu. About 10 percent people have been living there for many years, such
as
20
the Inuit(因纽特人)and Sami.
