In most ways, light helps us see things. But in recent years, because humans are using too much of it, it (cause) a kind of pollution. So it is difficult for us to see some of the most wonderful things in the life when we look up(watch) the night sky. In general, humans' eyes can see about 2,500 stars any special equipment. However, we can only see 200 to 300 stars from today's countryside, and no more than ten stars from a city.
, a study shows that lots of night time light can harm animals too. When birds fly to another place over cities, they sometimes get (lose) because of bright light and fly in (circle). Sea turtles (海龟) need dark beaches for (lay) eggs, but they can't find good places because of bright light.
In order to prevent things from going (bad), governments are working to reduce light pollution. Light is used only when and it is really needed. I hope humans and all the animals can live a good life under same blue sky again in the near future.
