Knowing what to eat is a very important part of survival but the body can last much longer with out food than without enough water and adequate protection against the elements. Here are some ideas and tips that might come in handy.
Always carry a container for water when you go off on long walks or experditions, you can always fill it up again when you drink all the water you have. Its important to get a good supply of good water but if this is not available you must boil all your water for at least 15mins to destroy all bacteria and 'bugs' in it. If you find that the supply of water is brown and has bits in, filter the water through a sock or t-shirt first.
The most important thing you should carry with you is a good knife.
