A Neighbor

I was looking over at a neighbor I have on the next hill over to my west, and for the past two weeks they have been burning trees and clearing the land and the edge of the hill. I have seen surveying going on over there and assume they are going to build on the land. Thing is they are taking down all of the trees including those on the down slope of the hill. It just looks so barren from what I can see since I still have all my trees at the edge of my hill. I am seeing this view high up on a ladder on my property.
