NASA's new 'Black Marble' images of the nighttime Earth aren't so black. They reveal that our globe is heavily littered with excessive and wasteful lighting that produces light pollution – a bright glow over our cities that not only masks the stars but wastes vast amounts of energy. Fixing the problem would cut greenhouse gas emissions, save money, lessen our impact on the natural world, and improve visibility on the ground.
