I think that Chris' reason for journying to Alaska was that it was probably one of the furthest places from home and it was beautiful there. He just wanted to get away from society and routine and his parents lies and live on his own with no responsibility. He lived his life to the fullest. Yes his death could have been prevented but it was definently an accident. He probably could have found different things to eat maybe. It means that you go out of society and into the wild. It was a good message and it teaches us how great nature is and how you should appreciate what you have and so on........
