You find yourself at the centre of an island that is one mile long and 100 yards wide. The vegetation is very dry from a long drought. Suddenly it catches fire at one end of the island, and a strong wind starts to blow it towards you. As the fire spreads it burns the whole width of the island. There's no beach, only sheer cliffs, and the sea is infested with sharks. 

What can you do to save yourself?
