We can actually infer here that the  main function of the sentence “Unfortunately, these clouds are not natural; they are the result of a personal habit that negatively impacts others” in the paragraph is that: It gives more information about the clouds hovering around the doorway.
<h3>What is main function?</h3>
Main function actually refers to the sole duty of a particular thing. It actually tells what something was originally intended to do in a passage or in a place.
