April 20-26, is going to be observed as the International Dark Sky Week. This is organized by International Dark sky Association (IDA). The aim is to encourage people to turn off extra light and thus help combating light pollution. This event was first celebrated in 2003 in the U.S. and from2007, it is being observed internationally. Also, April 20th is going to be The World Night. All over the world, the night of 20 April is dedicated to the appreciation of starlight and the promotion activities that showcase the breathtaking spectacle of the universe at night.

Redirecting Light: A New Mexico Model April 8, 2009

Shielded versus unshielded light

Shielded versus unshielded light

Do you have an unshielded light in your home or shop? If yes, be careful, you will be charged $25! don’t be afraid, at least for now this is applicable only for New Mexicans. New Mexico has had a Night Sky Protection Act for almost a decade. Now this act has been modified by stating that people who violate the law will be charged $25. It is required by law that outdoor lighting should be aimed downwards and light sources should be shielded. Laurel Ladwig of the Museum of Natural History says: ” … we are moving towards that goal where we can really take down a lot of that light pollution and see a lot more of the night sky.”

Laws like this that require people’s cooperation in controlling light pollution is very much needed though we can’t be sure that they will be 100% efficiently carried out. Something is always better than nothing.

We Can Do Something… April 8, 2009

Shielded and unshielded lights

Shielded and unshielded lights

It’s always better to prevent something bad from happening than to wait until it happenst. But, if it has already happened, the only way is to find a solution as quickly as possible. Same with light pollution. It is here, beside you and me, so, what we need is a solution. As we created the problem, we need to solve it too. What can we do? One day, I was discussing this issue with my friends. Suddenly, one of them asked: “What can we do? Can we go up to the sky and catch the extra light in sacks and bring it back to the ground?”  But what’s the need of thinking ridiculous things like this when there are solutions as simple as the ones listed below?
1. The easiest solution is to direct light into the ground where it is needed, and thus prevent the spill out of light into the sky where it is not needed. For that, shielded lamps of light sources can be used.
2. Another way is to turn off lights when they are not in use. Here, there are two benefits. Besides controlling light pollution, if each person follows the above strategy, how much energy can we save?
3. Reducing the intensity of light is very important too. Most of the time, we use more light than we actually need. For example, in my room, we have got four electric lights and sometimes, all of them are turned on. The case is not different in the common area in our apartment.
4. Control the misuse of light- this is very important. Especially while decorating our shops or cities or even houses, think of the harms that light pollution can bring about.
These are the things that I can think of right now. But, there are still more. If you can think of any, why don’t you share?

Why Is It Still Unnoticed? March 11, 2009

difference

Today one of my friends asked me what my blog is about. When I told her that I was writing about light pollution, she was really surprised. She asked me: “Is there a pollution like that?” Here, who is to be blamed? As I had said in previous posts, most people are unaware of the existence of light pollution. When Ms. Jen brought up this issue in our homeroom, a few months ago, I was a little confused too. Once I did ask her why we call this phenomenon ‘light pollution’? When we say water pollution, we are referring to polluted water. Same in the case of soil, air or atmospheric pollutions. So, light pollution should refer to polluted light. But when we read the article “Our Vanishing Night”, the confusion regarding the name was no more. Before that we had no idea about light pollution. Though it is discussed by scientists almost all over the world, the public is still unaware of it. It is necessary that the issue should be given much importance because it is very harmful to the existence of both humans and other living beings. We have already seen some of the many negative effects of light pollultion. Who should raise awairness? Of course, us. Who else? We are causing light pollution, each and everyone of us contribute to it. So, it is our responsibility to bring it to attention. What we can do is that we can tell our friends and families that such a phenomenon exists and we are the reason behind it. A small change can make a big difference. If we try to reduce the amount of artificial light spilled out into the atmosphere, we can save our country from light pollution. It is totally possible because our countries are not that affected by it. If we don’t act now, as George Eslinger, the former director of the Los Angeles City Bureau of Steet Lighting says: “the entire globe will soon be wrapped in a glowing envelope through which none of the magic of the Universe can be seen by the naked eye.”
