Of the many ways Earth is polluted, light pollution may be the least talked about. It's not an illusion; astronomers measure it from one to nine on the Bortle scale, and earlier this year, one study suggested that light pollution may be causing spring to come earlier. This short film, shot mainly in California by Sriram Murali, goes through all the levels of the scale, showing how the view of the cosmos gets better in less light-polluted areas.

About Short Film Showcase:
The Short Film Showcase spotlights exceptional short videos created by filmmakers from around the web and selected by National Geographic editors. We look for work that affirms National Geographic's belief in the power of science, exploration, and storytelling to change the world. The filmmakers created the content presented, and the opinions expressed are their own, not those of National Geographic Partners.
