In most situations, light helps us see. But nowadays humans are 
using too much light and it is in fact a kind of pollution.  
When it comes to looking at the night sky, too much light makes it 
difficult for us to watch some of life’s most wonderful sights: stars, 
planets(星球) and even galaxies(星系).According to scientific research, 
about 2, 500 stars can be seen by human eyes without using any special 
equipment. But because of light pollution, you can only see 200 to 300 
stars from today’s countryside, and no more than ten stars from a city. 
In most big cities, people cannot see the sky filled with stars as they did 
in their childhood.  
Light pollution affects more than just our view of sky. Research 
shows that lots of nighttime light can harm wildlife, too. When birds 
fly to another place over cities, they sometimes get lost by the

need dark beaches for laying eggs, but they can’t find their ideal 
places because of those bright lights.  
Too much light at night may even affect human health, but 
scientists are not sure of that. They are still learning more.  
In order to prevent things from going worse, governments and 
some organizations are working to reduce light pollution. Many cities 
and towns have taken action to reduce the use of lights at night. Lights 
are used only when and where they are truly needed. They also shine 
lights down at the ground instead of up into the sky and use lower 
brightness levels.  
Hopefully, in the near future, humans can enjoy the clear and 
beautiful sky again and all the wildlife will live a peaceful and 
undisturbed life, too.
