Why Education About Light Pollution Is Important

: Image via Wikipedia

Light pollution is a term that is hardly heard by people. There are many kinds of pollutions that are common these days. Water pollution, air pollution and other kinds of pollutions are very commonplace. In spite of the fact that these kind of pollutions are common, people do not bother about this. One other pollution that is rarely thought about is the light pollution. You can go to the website canada 411 to learn about the relevant information and places that can help you understand this fact.

The reason for the rarity with which light is heard about is because the light pollution is not something that can be very life threatening unlike the water and air pollutions. In spite of this, education about light pollutions is important because the light pollution has the potential to destroy the sight of people. These days, there are so many lights that in the night, if one is able to see the buildings that dot the landscape, it looks as if it is still day time.

There are many reasons for the education about light pollutants is important. As the increase in the intensity of the lights increase, it can lead to severe eye strain to the people. The eye strain can lead to early eye damage in any person who is exposed to continuous bright lights.
Other than the eye strain, the bright lights can also cause other problems in the person. They can lead to accidents because of the blinding lights that shine in the face of the person who is driving a vehicle. In fact, the number of accidents has increased because of the fact that there is a lot of light pollution.

Education about light pollution is important also because the night lights in various parts of the world cause the observatories not to be able to identify the starts and the other celestial bodies not to be observed properly. The high intensity lights have caused them to be difficult to identify.

Our Tiny Dot

Most everyone knows that the galaxy is an absolutely gargantuan place. Because of this tremendous size, it’s very easy to see how tiny we really are on this microscopic dot that we call the earth. While it may seem huge to us, on the cosmic scale it’s little more than a speck of dust.

The cosmic ballet around us stretches so far, but it can show us many interesting things about our own tiny dot. We can observe how massive amounts of things formed up by tracing their chemical components and watching them slowly spread apart. While a human lifetime is nothing to the stars above, our civilization can watch things change in the heavens and learn about how our own planet formed up all those billions of years ago. Of course, there are also some other lessons we can take in from all of this.

The most important lesson we will ever learn from the cosmos is the utterly beautiful nature of our own tiny pebble. While some people don’t think much about what the earth does for everyone and how hard it is to create such a planet, keep in mind that without earth no one you know could possibly survive. Also, considering how rare planets like earth are, doing anything to hurt the planet is more than just cruel and unjust. It’s more than a little stupid to purposely abuse your own ecosystem when you could be doing something far more constructive with your life.

What is Light Pollution? What Effects Does it Have on the World?

There is physical pollution, air pollution and even noise pollution. However many people do not realize that there is a thing known as light pollution. Although light pollution is all around the world and right next to a person, many people do not know about it or the harmful effects that it can have on the environment.

Light pollution is the term given to extreme artificial light that obstructs the night sky from any of the various areas. Light pollution is sometimes referred to as luminous pollution or photopollution.

Light pollution is usually caused by extreme artificial light, mostly from larger cities. These lights can come off of the surrounding buildings, advertisements and street lights. Anything that outwardly displays artificial light can be taken as light pollution in some way or shape.

The effects of light pollution can be extreme. The main effect that it has it that on the night sky. Most light pollution obstructs people’s view of the night sky and stars and prevents them from seeing the night sky naturally. In fact, in a recent study of the United States National Parks, it observed that every single national park in the United States is effected by some form of light pollution.

Another less obvious effect that light pollution has is that on the surrounding environment. Like the various other pollutions, light pollution can have major effects on the surrounding environment and ecosystems. For example, bats who are extremely light sensitive can often have problems with time and light if they are near a population that has extreme light pollution.

Some societies and governments have slowly started to address the issue of light pollution. In an effort to combat the amount of light pollution cities are implementing a strict curfew for large signs and building lights in an effort to try and reduce the amount of light that is visible in the environment.

How Education About Light Pollutions Can Decrease Health Problems

: Image via Wikipedia

Education about light pollutions is very important because it can help in the reduction of complications that occur because of the light pollution. There have been many people who have been affected by the light pollution, but they have not surfaced and become a issue because they are few in number. Compared to the other kinds of pollutions and the diseases that they cause, the problems caused by light pollution are not life threatening.

There are some common problems that occur in people who suffer from light pollution. The major problem is related with the eye. Increased strain to the eyes can lead to problems in the eye later in life. Other than the eye defects that are possible, there could be some permanent damage to the eyes too. In some rare cases, blindness can occur because of repeated stress to the eye over a period of many years.

The other problem that is common is that the person who is exposed to continuous light will suffer from confusion. The biological clock is programmed and the normal person will go to sleep as it becomes dark. The presence of light at all times makes it very difficult for the body to identify the normal rhythm and it is lost. This causes the person to have abnormal sleep. The decreased sleep because of the exposure to light can cause various chronic diseases like increased blood pressure and other severe complications like depression.

Adequate education about light pollutions can help the general public to learn the need to reduce light pollution. This will help to decrease the complications including health problems that occur due to the excessive exposure to light. Just like the other pollutions like noise, air and water pollutions, the light pollutions also need to be adequately controlled. This will help in preventing complications due to light pollution.

Light Pollutes in Two Ways

: Image via Wikipedia

Have you ever noticed that it’s rarely dark at night? Maybe youâ I’ve walked to your car after eating at a restaurant, or been driving down a deserted road at night, when you noticed the phenomenon. Not owing to the moon;s brilliance, the night is filled with light, and stars seem harder to see than in the past. It’s happening everywhere in the world, although America is near the forefront of the issue. The brightness at night is called light pollution, and it’s just another byproduct of human existence.

While most people are aware of the long lasting, detrimental effects of discarded plastic shopping bags, rechargeable batteries, and nuclear sludge from nuclear power plants, many are unacquainted with a non-physical pollution. Sure, even auto emissions have some sort of dirty, measurable quantity to them, and nearly anyone can picture a ton of carbon dioxide, particularly after witnessing a large truck with a bad exhaust pipe let loose a huge cloud of black smoke. But light pollution is less identifiable as a pollution, because it seems to emit nothing harmful. However light does create pollution, in two ways.

One is the obvious brightening of the night sky. Over 90% of America is now affected by light pollution, meaning that in only 10% of the country’s real estate, can one gaze upwards at night and truly drink in an unspoiled view of the surrounding galaxies. Even deep in the mountains outside of Denver, or Salt Lake City, light from these metropolitan centers bleeds into the view many miles away. It’s worse where there aren’t mountains to block the direct lights.

The other sort of light pollution is less obvious, but becomes more so by tracing the power source. Each lightbulb requires energy, and that energy comes from a power plant. Most power plants burn coal to make power. This creates emissions, but occurs far away from the light switch. That’s something to remember when next you’re gazing at the stars.

What is Light Pollution?

Light pollution is excessive light from artificial sources. If such light is obstructive in nature, then this situation is called light pollution. One of the problems in the environment that we are facing is light pollution. When you were driving on a busy highway, did you dilate your eye to get a better view of the road? If you have pondered why this happened, then you are facing a situation called light pollution. This is a case of ineffective outdoor lighting that is hazardous for commuters on the road. Most of the accidents at night happen because people did not see something they should have seen.

When too much artificial light is present in the surroundings, it causes visibility problems. It also causes a waste of energy. Human health undergoes a lot of changes because of altered light sources that are different from natural light sources. Natural light is the best thing for humans to have. It is natural light that provides photo-nutrition for life on Earth. And even human beings need natural light.

Light pollution is a serious issue, with a solution wanting to happen. People have begun to take cognizance of this issue. Light pollution is said to cause disruption to star-light coming to Earth. It also causes poor performance of astronomical observatories. Just like other types of pollution, it causes health problems for human beings.

Light pollution is a result of the industrial growth of the human civilization. You can see light pollution everywhere. Illuminated billboards, glaring motel lights, offices with lit floors, and in many more manifestations. In heavily industrialized areas, light pollution is more significant by its presence.

Light pollution does not do well for energy conservation. It wastes a lot of energy with unwanted illumination. Light pollution can also be intrusive in nature. Many people would have experienced how an artificial light source of another building trespassed into their living or working areas. This annoying condition is called light trespass.

What is Light Pollution

Light pollution is essentially misused or misdirected light that results from the misuse of exterior lighting products. Types of light pollution are sky glow, glare, and light trespassing. These types of light pollution are not only bothersome, but can cause serious health risks for humans and animals while also affecting the environment.

Sky glow is a type of light pollution that means light is entering the night sky and causing a glow over urban and suburban areas. This can cause many nocturnal animals to have nowhere to go during their prime time to hunt and eat. This of course means their numbers are dropping, but as they provide us with food and keep many smaller animals’ population under control we as humans are affected as well.

Another type of light pollution, glare, is the kind of light that shines dangerously into people’s eyes as they walk or drive by a home. This type of light can make it difficult for astronomers and everyday people to find star patterns in our night sky. We can no longer just glance up and find the milky way. It is much to hard with amount of light being projected into the night sky. Not only can we not see our constellations as clearly, we cannot drive safely or take walks at night, as there is constant light being projected into our eyes from all directions.

Light trespass is unwanted light shining into a neighbors property or home. This is especially important for people living in urban neighborhoods with houses being built closely together. Many homeowners buy fog or spot lights for their home as an attempt at crime prevention. Unfortunately, these types of lights are intrusive to neighbors and may light up their whole yard as well as yours. Some obnoxious lights may even light up the inside of the neighbor’s home, causing them to have to buy black out curtains to block the light.

Light Pollution, Its Impact And A Romantic Solution To The Problem

: Image via Wikipedia

What is light pollution? How can excess light cause problems? Well, balance is very important in nature. That is a reason why we have days and nights. For every 11 to12 hours of sunlight, we have another 12 to13 hours of darkness as well. The same is true for seasons as well.

If you have three months of summer in your region, you also have three months of monsoon, spring and winter to balance the entire cycle of nature. In such a scenario, excessive use of lights by human beings will obviously spoil this balance.

We often presume that light pollution is something that affects birds and other animals only. That is not the case. Light pollution affects human beings as well. Being exposed to artificial light all the time causes problems in internal activities of the body. Natural sunlight is not just an option. Rather, it is a compulsion for our body. If we ignore this, we obviously are going to face problems.

Secondly, being exposed to harsh light all the time places strain our eyes and the nervous system. If you feel that this is an exaggeration, just take a look at all those individuals who put in a lot of time and effort under artificial lighting.

Excessive light in urban centers during night confuses birds and affects their body clock. Ideally speaking, human beings should sleep early and get up early. The morning hours are the most productive for our mind and body. However, we often end up spending more time staying up.

Installing dimmers in your house will help even if you cannot switch off the lights. One ancillary advantage of this approach is that you can have a romantic dinner with your spouse by simply dimming the lights to set up a candlelight atmosphere. Not only will you be helping the environment, you will also enjoy a good time with your spouse.
