Could you turn off the lights?

During International Dark Sky Week, we're counting ourselves lucky to have this spectacular nighttime view, considering the astonishing fact that 83 percent of the global population lives under a light-polluted sky.

Not only does it waste money and energy, it also disrupts plants and animals, is believed to impact the climate, and blocks our view of the universe.
