What this story suggests is that there is a sort of antagonistic relationship between people and nature, but that people need nature nonetheless.
At the end of the story, the fire consumes essentially everything that the people had made. People have set up all of this technology to separate themselves from nature. This shows that there is something of an antagonism there because people are trying to create a world that does not really include nature. Nature then gets revenge by destroying the house.
However, we also see that people really need nature. When they destroy the relationship between themselves and nature, they also destroy themselves. The technology that they love so much (that also separates them from nature) has now destroyed them. It seems that they needed nature.
