LIGHT POLLUTION
The light pollution is one of the problems of environment because
● the artificial light foul up the natural light. Today it’s so
serious that the humans don’t realize it.
● this kind of pollution hurts the wildlife of animals and plants.
For example some scientific studies show that pollution
alters the flowering of plants, the migrations of animal and
the relationship between predator and prey.
There are two types of light pollution:
the first is in the cities where the lights are very strong and white
the second is outside inhabited centers where orange light is diffused.
This skyglow overshadows the stars light in two thirds of the inhabited areas of planet earth
