In each episode of "Into the Wild," Bell strands himself in a wild destination, a place where travelers often get lost and find themselves in distress. He'll parachute into tropical rainforests, then abseil down to deserts or lakes, and to the top of America's highest and most desolate mountaintops. In a real environment, Bell will use his professional survival skills to try to escape from danger and find a way back to human civilization. There are many more practical and exciting programs in wilderness survival. Among them, the most exciting one may be the food part in wilderness survival. Eating slugs, snake eggs and various insects raw makes us feel our Life is really happy. It also teaches us some principles of survival. In the wilderness, survival is the most important thing, and everything else can be put aside.
