This video on the challenge of increasing light pollution is a part of collaboration between International Astronomical Union's Office for Astronomy Research (IAU OAO) and Kainaat Studios. A companion essay for this video is available at: https://www.iau.org/public/themes/light_pollution/Stars in the night sky have played a crucial role in the history of humans on this planet. They have not only helped us in providing appropriate times for planting crops and in finding directions in the middle of deserts and oceans, but our queries about their nature have also sparked some of the biggest revolutions in human perceptions of our place in the universe.
