It is only one skill to have in the wilderness and perhaps the most important. Fire provides Warmth. A raging fire can keep you warm and your articles dry in bad conditions. Protection: a strong fire can keep you safe from predators. Signal: a good fire can be seen for miles away at night and white smoke from adding greenery to a burning fire can be seen a long way during the day. Purifier: A hot fire can be used to boil water and to make your water safe. Learning several methods of making a fire or having a redundant supply of fire sources on hand while traveling can give you many different benefits when immersed in a survival situation.
