Discuss the function of nature in this novel. Why do you think nature is very important to the characters in Frankenstein. plz help me

I'll answer your question concerning Shelley's
Frankenstein by looking at a different element or side of
nature.

Nature vs. Nurture is a central theme in the
novel.  Left to himself, without nurturing from his creator/father, the
creature turns into the monster.  Victor fails
his responsibility to take care of, to nurture, that which he
creates. 

The wild, natural man, then, does not turn out so
well.  Victor rejects him largely due only to his appearance.  As a result of this
rejection, the creature suffers from isolation, loneliness, emotional deprivation, and
eventually becomes a monster. 

Unusually, and perhaps
ironically, the creature, left to fend for himself in the world of nature so emphasized
by other romantic writers, does not absorb its goodness or touch the transcendent or
commune with it and experience transformation as in, for instance, Wordsworth's "Tintern
Abbey."  Nature does not lead the monster to acts of kindness.  His isolation leads to
acts of horror.
