There isn't much of a conventional setting in this poem, unless you consider the vague concept of "apocalypse" or the "end of the world" to be a setting.
but, "fire and Ice" starts off with two images of the end of the world. In the first image, the world is a great bubbling mess of fire, lava, and explosions. cities are melting and trees are burning. In the second vision, the world is an ice cube/a ice sphere. a extremely large cloud looms above the earth, and temperatures are so low that life cannot survive.
from there we move to a discussion from the speaker- we now have the image of him "tasting" desire, like Eve biting into the fateful apple in the Garden of Eden. then he rewinds the end of the world somehow, as if this were a film.
In the second apocalypse, things run different. Ice carries the day, driven by the hatred of people.
The natural fondness led to the domestication of pets like dogs. ... Many people no longer care about what happens to other humans The loyalty and the positive behaviors from pets make people feel comfortable around them.
I hope you understand.
My, your, our, and their are possessive pronouns since all of them describe themselves.
