Tagged since May 2009.| Survival skills are techniques a person may use in a dangerous situation (e.g. natural disasters) to save themselves or to save others (also see bushcraft.) Generally speaking, these techniques are meant to provide the basic necessities for human life: water, food, shelter, habitat, and the need to think straight, to signal for help, to navigate safely, to avoid unpleasant interactions with animals and plants, and for first aid. In addition, survival skills are often basic ideas and abilities that ancient humans had to use for thousands of years, so these skills are partially a reenactment of history. Many of these skills are the ways to enjoy extended periods of time in remote places, or a way to thrive in nature. Some people use these skills to better appreciate nature and for recreation, not just survival.

Secondary sources on survival skills, including those produced by the United States Army, and the Boy Scouts of America (priorities for an individual or group in a survival situation), formulate lists of needs to be met for survival. The needs for survival are differently conceptualized between sources; they may give six, or seven, or ten "needs" or "priorities." Furthermore, those sources often differ as to the relative priority of survival needs in a given survival situation. Some sources expressly acknowledge what seems manifest: that the order of priority of survival needs shifts according to the immediate situation faced. One widely circulated concept to help set priorities is called the "Rule of Three": Employing a mnemonic device, the Rule of Three states: 1. Humans cannot survive more than 3 hours without warmth (unless the individual uses proper gear to cope). Think: passengers of RMS Titanic surviving only a short time while dipped in the frigid water of the north Atlantic Ocean. 2. Humans cannot survive more than 3 days without water.
3. Humans cannot survive more than 3 weeks without food.
The Rule of Three is often otherwise formulated and is viewed by commentators as a rough guide. An aircrew reportedly lasted 8 days without water in a liferaft. People have survived without food for over twenty-one days; the survival of voluntary hunger strikes by persons in captivity over longer periods has been reported. In 1999, Alaskan fireman Robert Bogucki survived for 12 days without water and 36 days with nearly no food in the Great Sandy Desert, Western Australia, The Boy Scouts, in addition to listing seven priorities, use a mnemonic device, "STOP", to address the mental aspects of survival. "STOP" stands for "Stop, Think, Observe, Plan."  Shelter
Airmen of the United States Air Force construct a survival shelter during Arctic Survival Training in Alaska. Shelter is any thing that protects a person from his/her environment, including dangerous cold and heat and allow restful sleep, another human need. A shelter can range from a "natural shelter"; such as a cave or a fallen-down (cracked but not split) thickly-foliaged tree, to an intermediate form of man-made shelter such as a debris shelter, a ditch dug next to a tree log and covered with foliage, or a snow cave, to completely man-made structures such as a tarp,...
