Verlyn Klinkenborg, author of “Our Vanishing Night”, explains exactly why light pollution has spread. "We are diurnal creatures, with eyes adapted to living in the sun's light” (Klinkenborg pg.478). He explains that humans have filled the night with light, so we have an easier time adapting to the darkness. However, with this comes consequences with our actions. Klinkenborg is effective when persuading the audience that light pollution is a problem. Therefore, there need to be actions taken through sympathetic examples of animals that are affected, the trend of environmental activists, and scientific research. "Our Vanishing Night" explains the results of light pollution on the Earth. Throughout the article Klinkenborg uses examples of how

This is defined as Kairos, a promising moment for action. Which in this case, he makes the audience feel bad about the effects of light pollution on the environment in 2008. Klinkenborg speaks about an orange haze, “we've grown so used to this pervasive orange haze that the original glory of an unlit night—dark enough for the planet Venus to throw shadows on Earth—is wholly beyond our experience, beyond memory almost” (Klinkenborg pg.478). He brings this up to remind the reader that the night was dark but now the sky has a hint of light because of all the light pollution we have created. By trying to persuade the audience about the environmental issues that have come from this makes the reader want to learn more and maybe even contribute to help the cause. Klinkenborg uses another example dealing with the circadian rhythms of humans and animals, which is the cycle that tells the body when to sleep, wake, and eat. “The regular oscillation of waking and sleep in our lives—one of our circadian rhythms—is nothing less than a biological expression of the regular oscillation of light on Earth” (Klinkenborg pg.480). In this statement, he is influencing the reader with evidence that scientists have studied on the human and animal’s bodies through how the ecosystem works. By using the environment as a way to persuade the reader Klinkenborg gets his point across effectively and to back up his facts he follows this with scientific
