how does Robert Frost caution the common man-fire & ice poem?

Dear Student, Robert Frost cautions the common man by warning him about the causes of the end of the world . He says that the world can end in any of the way fire and ice . Fire and ice not only refers to the physical damage but the damage of human mind. He uses complex metaphors to refer to the path humanity is going towards in today's world. Fire stand for words and feelings like fury,intolerance,lust and greed whereas ice stands for cruelty,coldness and hatred. According to Frost all these negatives can also be the end of the world.
