In this lesson from POV, students will study the nesting process of the endangered loggerhead turtle species and watch a video clip that illustrates how artificial lighting along nesting beaches disorients turtle hatchlings and hinders their ability to reach the ocean successfully. Students will then identify ways that humans can reduce the threat of such lighting to natural habitat. The video clips provided with this lesson are from the film The City Dark, a documentary about light pollution and the disappearing night sky. The film asks viewers to stop and ponder what light, darkness and the stars mean to us, spiritually, physically, intellectually, socially and economically.
