Fire and Ice by Robert Frost

Some say the world will end in fire,

Some say in ice.

From what I've tasted of desire

I hold with those who favour fire.

But if it had to perish twice,

I think I know enough of hate

To say that for destruction ice

Is also great

And would suffice. 

In this short poem, Robert Frost tells us that if the world is to end, he would rather have it end in fire.  Frost compares the fire with desire and ice to hate, implying that the downfall of the human race could be caused by desire and hatred.  That, or Frost could have known about the 2012 end of the world situation, and he wants the world to end in fire.
