Isaac Newton is stranded on an island covered in forest.
One day, when the wind is blowing from the west, lightning strikes the west end of the island and sets fire to the forest. The fire is very violent, burning everything in its path, and without intervention the fire will burn the whole island, killing the man in the process.
There are cliffs around the island, so he cannot jump off.
How can the Isaac Newton survive the fire?
(There are no buckets or any other means to put out the fire.)
Also considering that he has got no other tools to dig the ground, would he survive till the end at that island?
