For most human history, the stars sh one brightly in a dark night sky. But today, with many man- made lights, it is difficult for us to watch some wonderful sights: stars, planets and even galaxies(星系). This is in fact a kind of light pollution.
According to scientific research, you can see about 2,500 stars without using any special tools. But because of light pollution, you can only see 200 to 300 stars from the countryside, and no more than 10 stars from a city. In most big cities, people cannot see stars like they did in their childhood.
The main reasons of more brightness of the night sky are industrialization(工业化) and the growing use of outdoor LEDs, which are much brighter than traditional lighting. It brings a lot of bad results. Scientists find it hard to see the stars and planets. And too much light might make birds lose their ways at night. Some insects(昆虫) often fly towards light and may knock into buildings and lose lives. Sometimes light pollution makes us have sleeping problems.
Small actions, big changes. To stop things from going worse, we should use the right amount(数量) of light, in the right place and at the right time. Using yellow- colored light instead of white light, shining lights down at the ground instead of up into the sky are also helpful. We'd better remind people around us to help cut down light pollution as well.
Hopefully, in the near future, humans can enjoy the beauty of the night sky again and all wildlife will live a peaceful life!
① Scientists see stars clearly. ② Birds get lost easily.
③Many insects may die. ④Some people feel sick.
