Original: The night sky is getting 10% brighter every year. We're forgetting darkness

Light pollution is causing the night sky to grow roughly 10% brighter each year, erasing the natural darkness that stars depend on. The Guardian reports on how cities' outdoor lighting and weak regulation are driving the change, prompting concern among astronomers and environmentalists who say people are losing their connection to the dark sky.

Why now: A new Guardian report on accelerating light pollution has renewed debate over urban lighting rules and the loss of dark skies.
