Big Toys!

I think I love polar bears most in the zoo. They are so cute and just look like big toys when they don’t move. So I spent a long time looking at them and took many pictures there.
Polar bears live in the Arctic Circle. As a reaction to the cold weather, they all have white thick fur which consists of a layer of dense underfur and an outer layer of guard hairs. In the zoo, I touched and felt one sample of their fur. It’s not that soft as I thought.
Even though polar bears are so cute, they are in danger now. I think global warming is the significant threat to the polar bears. Due to warm air temperature, ice melts earlier and earlier, driving the bears to shore before they have got enough food and built enough fat reserves to survive the period of scarce food. The pollution of industry and the expansion of human’s movement also lead the decrease.
If we don’t do something to protect polar bears, I think my children may only see polar bears through my pictures.

I love polar bears too!
We need to protect them otherwise they may leave us forever. For the sake of future generations,we really need to treat this problem seriously.

If we did not see the bears, maybe we will not think they are that special. But just being near them makes you realize they are worth protecting. I agree with you and Beth.
