This week:Reducing light pollution has numerous benefits for the environmentThe future of natural gas in the U.S.Why poppies sprouted on Europe's battlefieldsReducing light pollution has numerous benefits for the environment(Christopher Kyba)Typically, when people think about pollution, it's a question of air quality. Using satellites to monitor the light that seeped upward into space, the study found that light pollution dropped by just 13 per cent, suggesting that there are other sources of light that are causing pollution. But there's another benefit to reducing light pollution: less light means less energy production. Robert Dick, former chair of the light pollution abatement committee at the Royal Astronomical Society of Canada, said light pollution should concern everyone. "[People] should care about light pollution the same way they should care about reducing environmental pollution and designing cities to be sustainable," he said.
