Crystal's documentary aired globally and caused a huge response. People began paying attention to the Arctic and taking action to reduce carbon emissions. Crystal received letters from children worldwide, all promising to protect Earth. Dr. Chen said with satisfaction: "Your efforts have changed the world." Frost jumped happily: "Look! The glacier melting is slowing down!"
The expedition ended. Crystal stood on the ice, looking at the beautiful Arctic. The polar bear mother brought her healthy cub to say goodbye, thanking Crystal for her help. Frost solemnly said: "Crystal, you are now officially an Arctic Guardian. Remember, protecting the Arctic means protecting Earth's future." Crystal raised her right hand and made a solemn oath: "I will dedicate my life to protecting this white world."
