Of course, having a topographic map, compass, GPS unit, or just paying attention to the jungle can save you a lot of trouble.
Finding Food
Since the jungle is such an abundant resource of plants and animals, the resources for finding food are everywhere. It's just a matter of how to get access to it. Here are some tips for getting food in the jungle.
Hunting/Trapping Animals:
Don't waste your energy and time hunting animals. Conserve your energy for other survival tasks instead.
Your best bet is to trap animals while you are sleeping.
Using a deadfall trap is an effective way to trap animals and you can set up many of them to increase your chances of catching more food.
