Uninhabited Desert Island might seem like a scary proposition, but in reality your chances of survival are pretty high as long as you follow a few simple procedures and keep things in perspective. A desert island might have its own challenges but being close to the sea, having natural warmth and an abundant supply of food will all contribute to making your survival more likely than if you had found yourself washed up on an uninhabited polar coastline.
desert island or uninhabited island is an island that has yet to be (or is not currently) populated by humans. Uninhabited islands are often used in movies or stories about shipwrecked people, and are also used as stereotypes for the idea of "paradise". Some uninhabited islands are protected as nature reserves and some are privately owned. Devon Island in Canada is claimed to be the largest uninhabited island in the world.
Small coral atolls or islands usually have no source of fresh water, but at times a fresh water lens (Ghyben-Herzberg lens) can be reached with a well.
