They look just like ice and snow, so other animals can hardly find them easily. Polar bears are amazing swimmers. They can swim for a long time in cold water to catch seals and fish. They love sleeping in thick soft white snow. However, global warming makes the area warmer. The ice and snow melt quickly. Polar bears can hardly find safe places to live and enough food to eat. Their life becomes really hard. We can make animal profiles to share knowledge of polar bears. We can also take small actions to protect their home. 1.
