    This past summer I went on a journey to Canada’s Arctic with Students On Ice. When I left Calgary I wondered what I would find what I would learn and who I would meet. On the trip to Ottawa I was wrapped in a blanket of uncertainty and excitement. But when I first met the group of students, scientists and leaders, I knew that l didn’t have anything to worry about. The group was amazingly receptive and I was soon part of a big family setting out on an amazing adventure—an adventure of a lifetime!

When we reached the Arctic I saw a vast Land that appeared untouched and original. I was surprised by its great size and beauty and my senses were repeatedly shocked and amazed. I stood on the Kapitan Khlebnikov and saw twelve polar bears. They walked in search of seal holes, and patiently waited for a meal. I learned that polar bears are successful only one out of every twenty hunting attempts.

However, I learned that the Arctic and its people are being threatened by pollution and global warming. I learned that pollutants are carried by ocean and air and have a bad effect on all Arctic people. I learned that global warming has put polar bears at risk because a warmer climate means that they have a shorter time to hunt seals on the ice.

The trip was a feast (盛宴) for the senses. I have learned more about our environment, and particularly how alive and interesting the Arctic is and why it is so important to take care of it. I learned pollution, ignorance of individual and global problems need to be solved. The Arctic deserves to he preserved. My trip with Students On Ice has made me more determined to try to ensure that I do not leave harmful footprints on either Earth or its people.
