Suppose your friend told you that he or she was going to hike the Appalachian Trail, and this friend was completely ignorant about the threats posed by bears. In an expository essay, explain how hikers should protect themselves from bears. Since Bryson mentions the grizzly bear and the black bear, you may choose either bear as the focus for the essay. For this option, you will need to cite at least one wildlife expert as a source. Your thesis should answer this question: what are the most important precautions that a hiker should take to avoid being mauled by a bear and why?
