In a survival situation, you're probably lost out there in the wilderness. If you want to go home, then I have some strategies for you! First, you want to create a fire. Find the biggest leaf you can. Set it on fire. At night, wave it in the air and someone might spot it and save you! Another strategy is if you are in an open area where someone can see you, you can spell out the words "help" in big using leaves, rock, and all sorts of materials. Planes will see the words and come down to rescue you.
