What is the central idea of the poem?

The poem "Fire and Ice" was written by Robert Frost, originally published in 1920. In "Fire and Ice," the speaker explores two powerful emotions or motivators that he thinks could potentially bring about the destruction of the world. This includes fire, which represents desire in all its intensity, and ice, which represents hate in all its cold and bitterness.
The speaker himself admits that his exposure to the intensity of desire has led him to believe that it may be the force that ends the world.

From what I’ve tasted of desire
I hold with those who favor fire.


He then admits though that the world ending from hatred is also completely probable to him. Exploring the intensity of these emotions and how they relate to the prominent issues facing our world today, such as climate change, dangerous egotism, war, and xenophobia, will allow for a very competent analysis!
