Survival fire principles (introduction to "firecraft") - Wilderness Arena Survival
In survival situations, the ability to build and light a fire can make the difference between life and death. You can use fire to purify water, sterilize bandages, signal for rescue, drive animals from their homes, efficiently modify the landscape, smoke and preserve food, softening tar for adhesives, making charcoal for medicinal purposes, and provide protection from insects and animals. Fire not only cooks and preserves food, it also provides warmth in the form of heated food that saves calories our body normally uses to produce body heat. It can be a psychological boost by providing warmth, peace of mind, and companionship. You can also use fire to manufacture tools and weapons.
