This comment is hurtful, a view of a clear cut in a forest is more sad than beautiful… behind this view are hundred of thousands / millions of insects that are killed, death and loss of habitats for numerous small and bigger mammals … trailing in a natural environment is good when it brings you closer to its needs, more aware of its fragility, what you call beautiful is a loss of biodiversity for human productivity purpose
