In his article titled, “Let There Be Light”, Paul Bogard tries to convince readers that efforts should be taken to preserve natural darkness. He builds his argument using rhetorical devices such as a personal anecdote and concrete details to help persuade his audience that we should limit our use of artificial light at night. To introduce the reader to his argument, Bogard presents a personal anecdote of how dark the night sky was at his family’s cabin in Minnesota.
