Even though polar bears can cope with the cold, they just hate falling through the ice. They pick their way very carefully indeed. He spreads his legs to distribute his weight and progresses carefully. But it's not enough. For a hunting bear, it doesn't get much worse than this. The disappearing ice is also troubling the family. The ice is now so thin. It only supports the weight of the lighter cubs, leaving the mother struggling. On the way, she taught her cub the survival skills for what could be an ice-free future. More than anything, the cub learnt that curiosity is the key to survival.

Tom loved to explore. He went walk long miles in the mountains, looking for new things. One day, Tom and his best friend wanted to go to the top of a mountain. That mountain was almost unknown to other climbers. They would have to make their own path to the top. There, they found a cave. It was very dark inside. They took their flashlights and turned them on, so they could see where they were going. As they walked deeper into the cave, they found themselves in a big room. To their surprise, on the walls of the room there were drawings of deer, trees and people. Someone had been there long before and had made those drawings. They looked very old and fantastic. Tom took out his camera and took pictures of the drawings on the walls. When it was getting late, Tom and his friend had to leave the cave and go back. They decided to come again. Two weeks later, an earthquake destroyed the cave. So Tom and his friend never had the chance to see those drawings a second time. The pictures taken by Tom were the only proof of the existence of the cave.
