Classification of extreme survival

1. According to the difficulty, 1. Experiential outdoor extreme survival: This is what people usually play now, not in the deserted places, but in the remote mountains around the city or in the countryside (it is really difficult to find the limit, and most people are afraid to go because they find it difficult). Generally, they just bring a tent and a bunch of unnecessary survival tools (such as knives, magnesium sticks and kettles). 2. extreme survival experiment: customized lines, rules and tools, planned, organized and guaranteed experimental extreme survival activities, such as two series of Discovery Channel, Alaska Survival Experiment. This kind of activity is challenging, but it is also guaranteed. 3. Exploratory extreme survival: Go into unknown areas in a planned way, and carry survival tools as required, but unknown factors during the trip will cause great trouble. Although I have learned about the local topography and studied the vegetation types, my life is often in danger because of minor factors. (For example, Yu Chunshun was killed in Lop Nur because he missed a water supply point, and the friend of the protagonist at the beginning of the movie "Vertical Limit" turned back because of gunfire. Of course, there are also many successful cases. It is said that someone drove Chery QQ across Lop Nur several times. I wonder if it's true. What's the name of the guy walking in the no man's land in northern Tibet? The one who pushes the bike himself, let Du Niang go. These are also successful cases. 4. Disaster survival: The sudden fall of the sky or the tsunami and typhoon usually make people unprepared. At this time, if you can make full use of your survival skills and experience, you will bring more peace to yourself and the people around you. (Isn't there a family that has no worries after the Ya 'an earthquake, and no one in the family has prepared survival equipment? Of course, you may not need to be excited about this case. Second, according to the geographical features, 1. Jungle survival: For friends in inland areas, the most likely way to play extreme survival is to enter the jungle. Many people think that it is relatively easy to survive in the jungle, because there are many resources, water is easy to find and there are many things to eat. But on the contrary, the most dangerous living area is the jungle, especially the undeveloped virgin forest. Although there are many resources, there are also many dangers. (For example, carnivores such as lions, tigers, leopards, bears and wild boars, poisonous species such as snakes, scorpions and ants, eating some plants by mistake will also bring life risks, and the jungle scenery is complex, and it is easy to get lost or slip. ) I remind you with my personal experience of falling off a cliff: every step in the jungle is real, No.2. Desert survival: Many people think that the biggest killer in the desert is heat, and no one can stand it when there is water shortage. That's right, but don't forget that the cold at night in desert areas is also very deadly. There are poisonous snakes, scorpions and other species in desert areas that can also kill people. Of course, the most important thing is that you have to find the right direction, otherwise, no matter how much food and water you have, you can't go out. Therefore, personal advice: unless you have to go to the hinterland of the desert (I can't think of anything that makes people have to go), don't treat life as a joke. Thousands of kilometers are completely barren, with no species, let alone Bell. No one can go out. Don't believe the story of walking in the desert and reaching the oasis in programs such as Survival in the Wilderness. 3, island survival: shipwreck or plane crash, people may encounter islands to survive, some islands are actually very rich in resources, such as the island in Tom Hanks's "Survival on a Desert Island", which is simply a paradise, with coconuts and fresh water, but not every island is like that. It is possible that the place where you were washed away is just a reef, and you may be flooded at high tide. All survival manuals teach you not to drink sea water. It is true that the salt content of seawater is more than three times that of human body (0.9% for human body and 3% for seawater). Drinking seawater can lead to renal failure, brain water shortage, hallucinations and insanity one after another, and many people die because of drinking seawater. And those survivors who were rescued after the recorded shipwreck and drifted at sea for the longest time all drank seawater without exception (sigh: 4. Ice rink survival (snow): The biggest problem of ice rink is avalanche, which can be prevented if it is not prevented. The cause of the avalanche may be as subtle as a cough or a slight vibration like a cell phone ring. Of course, not to mention glaciers. The structure of the 10,000-ton ice shelf itself is unstable and may collapse at any time. There is also a big hidden danger that the snow covers up the geomorphological features, and you don't even know what you will step on next. Not to mention the low temperature. Many people don't know enough about living in a snow cave. They always feel cold, zero degrees anyway. Here's an explanation. Although zero degree is an absolute low temperature compared with our daily climate in temperate zone, it is an absolute high temperature that can guarantee human survival compared with the windy mountains and snowfields of MINUS ten or even dozens of degrees. Remarks: If you want to survive in the snow, you should go to low altitude areas as soon as possible. In the area above the snow line, the temperature will rise by about 65438 0.2 degrees for every 200 meters of sea level drop. 5, swamp survival: stay away from water, stay away from water, stay away from water that can't see the bottom of the water, and keep your feet dry. When it exceeds 1 1 hour, the wet skin of feet will rot, commonly known as trench feet. An American guy walked in Amazon for nine months, and there was no trench foot except a bug laying eggs on his scalp. Finally, he cut his scalp with a knife and saved his life. American alligator is the most important one. As a jungle river with a width of more than 300 kilometers, the Amazon River is definitely the most classic area for swamp survival. All I can say is, swamp survival It's okay. Stop calling it a swamp.
