Raise awareness about light pollution to preserve and protect the nighttime environment.
Light pollution is not easy to recognize, but it is a threat to our environment.
The effects of excessive artificial lights not only threaten astronomy and ecosystem, but also impact human health.
In fact, it is not hard to solve the problems.
Just turn off the necessary lights and reduce total light in the environment.
Everyone could help Earth to bring back the spectacular night sky.
