There are loads of food in the wild and/or outdoor terrain, a few of these are pine trees: You can cut to the cambium layer in a pine tree and you can either eat it raw or just cook it for a better taste (maybe add salt to make chips but is not required as, because you are in a survival situation..). You can use the pine needles and boil them in water to make tea that is loaded with vitamin C but take them out of course or you might find it very unpleasant. Dandelions: You know the yellow flower that weeds just about everywhere you go? They are edible the whole flower to the leafs and root. The younger leafs that are just sprouting taste better as they are more sweet while the older ones or already grown ones are bitter-tasting but on the whole they are edible and have a decent amount of nutrition. Bears scrounge on these all the time as they are mostly scavengers than hunters. Insects: Please don't forget about insects/bugs as only a few are poisonous compared to the ones that are!! Ants, worms, even moths, are examples of edibles. For myself i would rather fry em up in a pan and maybe add a seasoning if you have any with you but are fine as they are or without season. You can dig in the dirt to find these bugs, look on trees, by natural water sources, plus sometimes on rocks or under them. These are just a few and maybe it helped if you didn't already know, But the ones who are willing to do this will most likely be the one's to survive in a survival situation for longer amounts of time. If anyone wants please mention other natural edibles so others can learn for last resort foods!!
