___________
Answer: If you are in a desert environment, try to build an underground shade shelter to avoid prolonged sun exposure, obviously only for hot climates．So you can be more comfortable in cooler temperatures to avoid sweating．If your environment is damp, use branches laid and criss-crossed on top of one another to create a solid and dry foundation for an open bed pad．Raise the foundation above ground level as much as possible．
_________
Answer: Yes, I think so．For example, if you think the best survival course of action is to look for help and civilization, don’t wait 4 or 5 days before you come to this conclusion．Take action on the 1st or 2nd day if possible while you still have strength and endurance working for you．
_________
Answer: Use dry wood and sticks to start your fire．Fire is started by using three kinds of wood: tinder, kindling, and fuel．Tinder is any kind of flammable wood shavings, usually light and wispy．You can take two pieces of dry wood, sharpen one of them and use it to drill into the other piece．Place any highly flammable objects you can find next to the drill bit．The moment the flammable object catches a spark, use a rock to swiftly tip the object onto a nest of leaves and little branches．
__________
Answer: Get an ordinary block of wood and hit it with a rock repeatedly until the wood sharpens．In this case, use the rock as your sharpener．You could also take a rock and break off some of the edges and then use another rock and some water like a wet stone and sharpen．In an ideal situation, obsidian stone would be used for its infamous sharpness．
___________
Answer: Use two more sticks to hold up a “teepee”, similar to your shelter．Place an item of your choice you think an animal will come after, if you’re lucky, the animal will be trapped．Dig a hole in the ground about 2m-3m deep and 1m-2m across．Take two thin branches and place them criss-crossed across the hole．Cover it with leaves and put something the animals like to eat．You can also put a few wooden spikes sharpened by your knife at the bottom．Don’t forget to build a ladder or you might not be able to climb out of the hole．
