There are a lot of kinds of pollution that are around us such as water pollution, air pollution, and light pollution. Being a boy lives in a city, I can strong feel that the air is seriously polluted but what we have loss concern is about the light pollution, and it is always important because we use light all the time.
To define what is light pollution, we can separate it in to three kinds of light pollution: white light pollution, artificial daylight and IPL pollution.
White light pollution is cause by the sunlight. During daytime, when the sun light shines in to the city, it will reflect by those glass on the window, bricks and all kinds of material which can reflect light. You may just think it is just a piece of cake- it is just only a sun shine, but the harmful effect of the white light pollution are all direct to human’s body. Some researcher give a conclusion that those people who live and work in the atmosphere that have white light pollution will have some destroy on there eyes and decrease there eyesight. Also if you stay in a place that was full of strong sunlight, you may sometime feel dizzy and can make you feel down.
Artificial daylight is a kind of pollution that cause by the advertisement board during night. Because that light on the board is too shining and makes the city was just like the daytime so that’s why we called this artificial daylight. People who live in the all-day-light city can’t have a good sleeping time because the manmade light is too strong and makes people can’t go dream very well. Thus it will cause the people is not efficient on either working or studying. By the way, artificial daylight will also affect birds and insects.
IPL pollution in another way we can explain it to colorful light pollution, we can found this kind of pollution in the clubs or KTV. Why this beautiful light can harm our body? Because the UV they create is much stronger than what we can get from sunlight. As we all know, UV can cause a lot of health disease the most common one is skin cancer. Also those colorful lights are not good for our eyes and may affect our nervous system.
As we can see, those harmful effect can cause a lot of problems, so what we need to do is decrease and take control of it. To decrease the disadvantage of the light pollution, I think the key point is arrange of those light source carefully. This can solve the problem of the artificial daylight and the IPL pollution, because this two of the light resource is all create by our human, so if we arrange our light resource reasonable, I think this can slow down this problem. But how can we solve the white light pollution? Because the white light pollution is cause by the reflection so these may most occur in the city area, if we make a control on the building materials so that the reflection won’t be so strong this problem will be decrease. On the other hand, if the government have release some policy to control the lightness of those light in the city, this can cause those light not be so shine and ease a lot of problem. In addition, I think the most efficient way is to use new kind of energy-saving light resource, because those light resource is much clean than what we are use now and those light resource is not that spin on eyes so it will be good.

By considering the way to solve the light pollution, we must also thought about effect related after the solution. If we solve this problem by decrease the strengthen of the light in the city, it may someway solve the problem but on the other hand, it will also leads the road become more darker, in my opinion, the strengthen of the light in a city was been carefully calculated, so when the light gets darker it may increase the rate that a traffic problem is happened. Plus, if we make a regulation to some place like club, those light will not be stimulated to our eyes any more but if the light of the club was not that shine than before, it will decrease the customer in the club, because people tend to have that kind of atmosphere in the club. By the way, the club can’t earn that much money anymore and some may run out of business, it will leads them to pay less income tax and may not pay tax because corrupt. So the government can’t earn this part of money and loss some part of the money that can contribute to the society.
Hence we know that every coin has two sides, so does the solution due to the light pollution, what we needs to do is Take care of this problem and use the most effective way to do the right job to the society.
Also, from the Economic point of view, if we control the strengthen of the light in the city, it will have a negative effect on it. Just imagine that the place where you live is a tourism or a international city, it is necessary to let the light in the city become more bright to attract people’s eyes, so when more people come, in an other words, it will bring us more income and it can leads to the increase of GDP by the way. For example, Hongkong is a international city, when you were living in Hongkong, you may never feel that there has a night coming to you. Plus, if you were on plane and it is going to touch down, you will see how beautiful the city was by the creation of the light.
