In the survival environment, water is one of the most important requirements. Without water, people could not support how long, especially in hot areas, a large number of sweat has lost a lot of water. Even in cold areas, people need at least a day 2 quarts (2.3 liters) of water to maintain normal physiological needs (see chapter 3). Three-quarters of human body is made of water. Hot, cold, hard, tension will make human body lost moisture, loss of water must be added in order to maintain the body function properly (see chapter 3), so you are one of the most important task is to get enough water. To get water to some extent, almost any environment water. Note: if you don’t have a water bottle, cup, pot, or other types of water containers, you can use a plastic or temporary do a waterproof fabric. Fold plastic or waterproof cloth into a bowl, with a pin, sharp bone, or other suitable, even one who holds your hand and hold the place of the sale. If you don’t have a reliable source of water supplement, so be aware of the surrounding environment, all the way might help. Dew can also provide the moisture. Tie some clothes in the ankle or several beam of thin grass, before the sun rises through the dew covered with grass, when the clothes or grass beam absorption after the dew, put water into the container. You repeat the steps until to get enough water, or dew has evaporated. Some Australian aborigines can use this method in under an hour to get 1 quarts (1.1 liters) of water. Bees or ants climbing into a tree hole may indicate the hole with water. You can use the plastic tube to suck out the inside of the hole, water or made of temporary spoon to dig out the inside of the water, or put the clothes into the hole absorb water, and then twist the water out. Sometimes water accumulation in the tree farm, or in the cracks of the rock, in the same way mentioned above can get water. In arid regions, bird droppings may signal that near the cracks near the water. NenZhu Lin is a wonderful drinking water sources. To collect from the NenZhu water is clean, and no peculiar smell. When collecting water, put a NenZhu bending, the top will be tied to the ground, cut the top.
At night, the water will drip from bamboo. The old and cracked bamboo may have water storage inside. Warning: drink before must first to water purification. If it is found that banana and plantain trees, you can find water. Trees are broken, one foot (0.3 meters) high stumps left, in the center of the stump place to dig the mouth of a bowl, root water bowl infiltrated the immediately, the first three times of water might be a little bitter, but after the flow of water can drink. Stumps to be able to continue to supply 4 days of water, pay attention to taking something must cover the stumps, lest insects inside. Some tropical vine plants can also provide water. Cut a hole on the vine, the higher the better, and then cut off near the ground, make water droplets into the container, or directly drops in the entrance. If the water is sticky, cream-colored or taste bitter, then don’t drink it. Green (green), coconut juice is very good thirst drinks. But mature coconut juice contains a kind of oil, can cause diarrhea, so drink in moderation. Tropical regions in America, you will find some tall plants grew on the branches of many air plant, the overlap of these air plant or thick leaves may contain a lot of rain. A cloth filter to remove insects and debris. Some plants have stems soft juicy, you can also obtain the moisture. Cut a plant, squeezed the fleshy part of the SAP flow, in containers. The roots of plants can also provide the moisture. Dig out the plant root, cut into small pieces, the skins, then suck, usually suck water. Fleshy leaf or stem, such as bamboo stem, usually containing water. At the site of the section cut stem, pour out the water inside.
Trees can also provide water of the following:
Palm plants, such as flat palm, the coconut trees, arenga pinnata, nie lv, etc., all contain water, fracture of lower leaves, tree will come from “wound” water seepage.
Low travelers Manila in Madagascar have cup-shaped leaf sheath in leaf base, there often have water storage.
Low in west Africa tropical magnolia leaves and roots can provide water.
Low Australia
The northern plains and sand Africa baobab, cylindrical trunk can store water in the rainy season. Usually in the dry season are just a few weeks after the beginning of the can find water from these plants. Warning: the juice was obtained from the plants don’t save more than 24 hours, because it will start after fermentation, drinking can be very dangerous. Still need it to be all over the world, it can absorb moisture from the surface of the earth and plant, but you need special material for distiller, also need a relatively long time with distiller to collect water, collect 1 pint to 1 quart (0.6 ~ 1.1 liters) of water takes about an hour or so. Produce distiller: there are two types of distillation vessels are used in the ground and underground. Used in the ground, as shown in figure 5-6. You must be placed in a sloping ground with sunlight distiller.
Specific steps are as follows:
To remove the condensate in the distiller, to loose mouth, tilt the bag to make small stone out of condensate water. And tie your mouth again, place the bag, in order to obtain more water, for the ground below the distiller, you need a mining tools. To choose a place to be sure that the soil contains water (such as a dry riverbed, accumulate in low-lying point) or rain, there must be easy to dirt, and must be in the most of the time of the day to receive the sunlight.
Specific steps are as follows:
You can use a straw to drink water, so will not interfere with the distiller continue to work. You can also put some green plants in pits as water, if you want to do so, you need to be in the side of hole dug up a slope to place plants, the next step. If you are the only source of water is polluted, can from the distiller 10 inches (25 centimeters) edge dig a sink, sink deep approximately 10 inches (25 cm), about 3 inches (7.6 centimeters) wide, pour water into the sink, be careful, don’t let water splashed soil near the edge of the plastic film contact. Sink function is to store water, so water will first before flow into the distiller through mud filter, and then water condensation on the plastic film, drop into the container. When you are the only source of water is salty, this method is especially effective. How to purify water with a clean container to collect rain water, or to collect water from plants generally can be directly drinkable, but from lakes, ponds, swamps, spring, or streams, especially from those close to human settlements or tropical water water, must purify first before drinking. Obtained from plants or ground water, if possible, be sure to use iodine, chlorine disinfection sterilization, or boil. You can use the following method purify water
Note: to do so will only make more better the taste of water, before drinking or purification. You can use a few inches or a few layers of filtering material to do a filter, filter material can be used sand, gravel, charcoal, bamboo internal membrane, hollow logs, or a piece of cloth, etc. To remove the peculiar smell of the water, and charcoal can be put into the fire, placed more than 45 minutes to drink again.
