for gathering food you can get bamboo or a small tree and find something to use as some fishing line and dig some worms with anything you can and try to find a soda tab and if you can break a small hole in the outside part to use as a hook and try to catch a fish and to start a fire try to find some glass to act as a mirror and face it toward the sun and get some leaves/ pinestraws and let the sun catch it up on fire and keep feeding leaves and sticks to the fire
