Once upon a time Bob and Bill,two bears, lived in the North Pole with their best friend Sam , the seal. They loved playing together and discussing. The bears' parents didn't have a problem with this friendship but Sam's mum told him to be careful because the bears are dangerous.

" Fish are dying because they eat rubbish that people throw in the sea, my boy" Sam's mum said. "The need for food sometimes makes them do bad deeds."

"Don't worry ,mum. There is no way a bear harms me. They know that I'm a friend of Bob and Bill " Sam said.

But his mum was worried and didn't agree with him.

One day the three friends were discussing.

"We are very sad because our parents told us that we are leaving" said Bob.

"Why?" Sam asked.

"Because the ice is melting and we do not have food" Bill told him.

"Mum says that people are responsible for this situation but I don't know why"Bob added.

While they were discussing two hunters appeared and told them:

"Don't be scared, little bears. We just want a seal's skin."

"What do you want it for?" asked Bob.

"We make shoes and bags" a hunter answered.

Suddenly two big bears appeared . When the hunters saw the huge bears, they were terrified and they ran away.

Sam's mum saw everything and rushed to her boy.

"Did you see , mum?"Sam said. "You should be afraid of people, not animals."

In the end , Bob and Bill's parents decided to stay in the North Pole so that the three friends were together.
