Let’s imagine that I am marooned on a small uninhabited island in the middle of the Pacific Ocean. The first thing I will do will be investigating of the island to make sure that there is really nobody to help me. Then I will try to find the source of fresh water from a stream or waterfall on the island. Also, I will collect vegetables, fruits from the plants on the island. Of course, I will eat food that I know not to be poisonous like coconuts or bananas and will avoid potentially poisonous, unknown berries. Except this, I will hunt for fish and try to find mollusks, crabs, oysters, and seaweed. When the food and water problem will be solved, I will construct a sturdy shelter from the leaves and branches. I will be located under the trees. The shade from overhanging leaves will keep me cool during the day. After that, I will make a fire. It will keep me warm during the cold nights and I can use it to cook any fish or animals that I will catch. In the case of wild animals attack, I will make a sort of spear from the brunch to protect myself. Finally, I will solve the most important problem: how to leave the island. I will signal to passing ships and planes by making three large fires in a triangle If during few weeks nobody helps me, I will build a sturdy raft and leave the island on it.
