How long has it been since you've seen the stars?
When you ask this question, you realize that you can't remember the last time you saw a starry sky.Starry sky, this again and again normal but natural phenomenon is becoming the illusion on the paper, look at the stars more and more become extravagant hopes.
Recently, small editor accidentally saw a documentary film "the dark side of light" shot by a German, let me see the other side of the light, also told me the culprit of the disappearance of the stars -- "artificial light", is also people have been concerned about but not effective control of the "light pollution" problem.
Ever since Edison invented the light bulb to illuminate the world, light has been a symbol of progress and luxury. Artificial light turns night into day, allowing people to play round the clock.Especially in today's China, driven by the economic and political factors of night travel, major cities are racing to create and improve urban night lighting. More and more buildings are wearing "light clothes", and the city lights are brilliant at night, as bright as day.But there is no denying that artificial light, while bringing convenience to people, also has a negative impact that cannot be ignored, not only affecting stargazing and animal behavior, and even affecting human health.
Today, I share this documentary, hoping to bring all lighting people thinking, in practical work can be reasonable light, moderate control of light, from the source to curb, for the global light pollution problem to do their part.
