What is a quote from the book about the setting?

The novel Hatchet by Gary Paulsen is set in the Canadian wilderness.
After a plane crash, Brian is stranded in the wilderness, alone and terrified. The wilderness plays a very important role throughout the novel, as it pushes Brian to learn to survive. The only thing which Brian carries with him is a hatchet that his mother gave him.
Throughout the novel, Brian grows, develops his survival skills, and learns to work with wood, crafting weapons in order to hunt and fish. He quickly learns that self-pity has no place in the wilderness.
The wilderness is not some beautiful landscape to admire. It is dangerous and mistakes can be fatal. Often it is presented in stark contrast with the city, to which Brian is accustomed. Brian must learn to live in this new reality which is so unfamiliar for him. In the following quote, Brian reflects on how the wilderness forces you to be sharp and on your feet at all times. In the city, on the other hand, mistakes can more easily be rectified.

Small mistakes could turn into disasters, funny little mistakes could snowball so that while you were still smiling at the humor you could find yourself looking at death. In the city if he made a mistake usually there was a way to rectify it, make it all right. Now it was different.
