HOW TO FIND WATER IN THE WILD
Getting lost in the wild is something that could happen to just anyone. The single most important thing you need to live is water. If you’re resourceful and know where to look, you can find or collect good drinking water in just about any environment on earth. Here are four top tips:
Find a muddy area
Dig a hole about a foot deep and one foot in diameter(直径) and wait. You may be surprised to find that the hole is soon filled with water, which will be muddy, but straining it through some cloth will clean it up, and it will get you by in the short term. It’s crucial to remember that any time you drink found water without purifying it, you’re taking a risk.
Look for plants
In a desert, look for where plants are growing, as they need water. Try to get up high and look downwards, as water is often found in low shaded areas.
Desalinate seawater
On an island you’re surrounded by undrinkable water. You can boil it and capture the steam in a cloth. When it’s soaking wet, you can wring out pure water.
Cut the ice
If you are in Arctic, eating snow doesn’t actually get you much water. And melting ice needs lots of fuel. One good way to get water is cutting through a frozen lake or river surface.
Warning: Beware of bad water
Never drink from water that has dead animals or animal remains in it. The water probably has lots of minerals in it and has become toxic. You have the same problem with seawater—it’s too salty to be healthy to drink. Sadly, birds and animals can sometimes drink water that’s unsafe for people, so you can’t ignore other clues if they’re drinking water that looks bad.
