In fact, light pollution is also a very serious pollution, it will also harm the bodies of people and animals, and destroy the ecological balance. The public is always concerned about water pollution and air pollution, which are easy to detect. Few people remember how beautiful the starry sky was decades ago. I want to tell people through my efforts that it's time we start paying attention to light pollution.
