Via BoingBoing, a beautifully shot video by Sriram Murali showing the damage done by city lights.
Shot mostly in California, the movie shows how the view gets progressively better as you move away from the lights. Finding locations to shoot at every level of light pollution was a challenge and getting to the darkest skies with no light pollution was a journey in itself. Here’s why I think we should care more. The night skies remind us of our place in the Universe. Imagine if we lived under skies full of stars. That reminder we are a tiny part of this cosmos, the awe and a special connection with this remarkable world would make us much better beings – more thoughtful, inquisitive, empathetic, kind and caring. Imagine kids growing up passionate about astronomy looking for answers and how advanced humankind would be, how connected and caring we’d feel with one another, how noble and adventurous we’d be. How compassionate with fellow species on Earth and how one with Nature we’d feel.
This is an easy problem to fix. On the political front we could start by getting rid of billboards like the mayor of São Paulo did. On the technological front, there are a lot of lessons to learn from the lighting designers of the High Line in New York.
