Light Pollution: Problems & Solutions
What Is Light Pollution?
No one can give the exact definition of light pollution but if the kinds are known, then it is possible to define the problem. As what Bakich mentioned in his article, light pollution has three types: needless light comes inside people's properties(light trespass), high deference between lit and unlit areas(glares) and ugly designed light groups(clutter)(2009,p.56).
What Are The Causes And What Do They Affect?
There are many sources of light pollution and they are easy to be recognized. Streetlights, for example, are the famous source of light pollution because the light they produce is not exactly directed to the street. This causes lots of distributed light quantities which pollutes the sky. Billboard light is a good way to waste the beauty of the sky & people's money(Serling, Bunch & Jones, 2009, p.38). Actually, these sources are using a lot of energy to produce light. To get that energy, electricity companies need to burn tons of petrol which will rise amount of carbon dioxide to the atmosphere. This in turns leads to the global warming(Astaire & Lot, 2008, p. 3).
How Can This Problem Be Solved?
It is easy to find a solution but people must be educated first. This is the government's responsibility to educate people and give them the solutions. Actually, people need to be told about the major effects and how that issue can affect them. After that long educating process, everything will be changed easily.
One of the solutions is to use motion sensors. Some people keep the light of their houses lit for a long time without switching it off. Using a motion sensor will help them to lit their houses at night automatically. Sometimes, people have small things to do
during the night and they don't need to use the light. They should get used to the dark, in fact, our eyes can see at night(Bakich, 2009, p.58).
Drivers, who drive at night, need to see the road perfectly. Rather than using streetlights to lit the dark areas in the roads, reflectors are recommended to be used so the pollution will be reduced. Also reflectors are much more cheaper and they cost nothing(Bakich, 2009, p. 58).
Conclusion
In other words, people must cooperate together to stop polluting their world and start a clean, beautiful and worthy life. The time is running and the issue will never stop by itself. As what Mr. Bakich said "with just a little bit of thought and effort, light pollution is one type of environmental problems that can be cleaned up without any side effects"(2009, p. 58).
Recommendations
Through a half century ago, Saudi Arabia has become one of the leading industrial countries in the Middle East. Many factories, stations and industrial cities have been established and built. Most of light used to lit these places is useless. The government needs to take care of this problem to prevent the occurrence of light pollution in the world. Some may say the world will not be affected by our carelessness. Actually, what affects one place has the chance to affect other places(Serling et al, 2009, p.38).
