Answer:
The conclusion of Frost´s poem is that human nature will most likely be the cause of the destruction of Earth and humanity.
Explanation:
In “Fire and Ice” (1920), by Robert Frost, the author reflects on the possible ways the world could come to an end, by fire or ice. He claims that fire is the most likely, in reference to the possibility of the sun becoming a red star that burns Earth. However, fire is a symbol of desire, meaning that Frost fears the human pursuit of fulfilling every desire could lead to the destruction of the earth, in reference to the gruesome outcome of World War I. Ice, symbolizing hate and indifference, is also an effective way to destroy humanity, according to Frost.
