What is the author's tone in The River Mumma Wants Out by Lorna Goodison?

There is a tone of disinterest and lack of caring. Compassion and responsibility for the land, the people, and the culture, which were once foremost in the River Mumma's role, have been discarded, according to Goodison's poem. In seeking the material pleasures of life, the River Mumma has forsaken her environment.
