Answer:
According to Wendell Berry, we consider a poem as "nature poem" if it has nature as a subject matter in the poem.
Since, the poem "There Will Come Soft Rains" describes the relation between nature and man made disasters. It describes how beautifully nature recovers all of the loss that we cause to earth.
It clearly has nature as a subject matter.
Thus, we can say that it is a nature poem.
