Light pollution happened slowly at first which was several decades ago it was a process that was hardly noticeable. A light here, a light there, burning way into the dark nighttime realm, helping us see in the darkness when people all their our beds fast asleep. The process still continues today, with little thought ever given to what we are stealing away. Our intentions are good but our methods need adjustment, and they needs to be done immediately. In fact, our methods should have been changed years ago, but nearly everyone has resisted, perhaps due to a profound lack of awareness. The use of too many lights at night can cause environmental pollution, known as light pollution. Light pollution can block our ability to see the original shining stars, which can affect people’s discoveries in astronomy. But since the lights are also very important for us at night when we are driving or walking alone on a street, I think there are certainly some solutions for protecting our natural environment while we can also use the lights at the same time. To admire the beautiful stars in the sky instead of looking at it in a picture, we can start to save energy resources by cutting off some unnecessary lights such as commercial building lights, outdoor residential lights, and by using shielded light to reduce the amount of light that we use in certain areas.
Light pollution is when sky glow produced by the scattering of artificial light caused by the poor quality of outdoor lighting (Nakata) causing too much wasted light dispersed upwards. Therefore recent studies show that “Nationally, more than 30% of the electricity generated for outdoor illumination is simply squandered by being misdirected into the sky. That comes to 4.5 billion dollars annually” (Lipsitz) for the electricity generated to send light into the sky and across property lines where it serves no benefit. Wasted light sent to the sky needlessly and seriously affects scientific research today for professional and amateur astronomers along with some NASA research. Astronauts have complained about this problem for years. Astronomical observatories are closing down because they can no longer see enough celestial objects to justify continuing their funding or research. For example, the Hubble telescope’s research is interrupted by light pollution, it was affected so much that astronomers did not get to see certa...

... studded with tiny points of light coming from countless miles away will return again where they belong, where they have always been since the dawn of time itself, and where they should remain for countless generations to come” (Haas,). Starting from today, we can do a little to help protecting our homeland that everybody shares, and give the chances to see the real stars in the future.

The USA should increase its funds towards NASA because the life on Earth will come to an end, and humans will need a new place to call their home. The Earth’s biosphere has merely one quarter of its life left (Garlick). The greenhouse effect is when gases, such as CO2, allow for sunlight to shine down, but prevent the floor from emitting its infrared heat simply back to space. Although the Sun is currently growing, leading to a decrease in CO2, the Sun’s gradual expansion will intensify the atmospheric concentration of...
Does one ever think of the potential catastrophic harm they’re causing by turning on the lights or by using their cars? Don’t we want a world where our grandchildren and great grandchildren can live safety and comfortably? At the rate were going this will not be possible; we’ve added more than 1.4 trillion tones of Carbon Dioxide (CO2) in just two hundred years, and its messing up our planet (Siegel 1).
More recently, many cities have adopted LED street lighting. It was only a couple of years ago when I first learned how to drive and got late from a weekend out that I noticed how rampant the use of LED lights is in the street of my town. Many of the roads that had orange lights are adorned with the more intense white light. Besides creating unwanted glares that make driving difficulty, these lights brighten the sky and take away the joy of stargazing. While the color rendition of the white light is outstanding, the high intensity takes away any pleasure for stargazers. Shielding the LEDs can reduce the glare and light spills (Falchi, Fabio, et al 2715). However, just a week ago, when I decided to write about light pollution, I got out of the house and realized how the snow is contributing to light pollution by reflecting light to the sky. Indeed, it is for this reason that the most light-polluted sky nights occur during the winter. LED lighting only helps in exacerbating the
Light pollution is one of the inevitable problems of the prosperous cities all around the world, including Hong Kong. The brightness of the night sky in Hong Kong is 82 times higher than the International Astronomical Union standard and the average night sky in urban is 15 times brighter than rural area (Daniel, Michael, Marina and Gregory, 2010), where Causeway bay, Tsim Sha Tsui and Mong Kok, are especially severe. Street lights, car headlights and advertising lights are the major sources of serious light pollution. In between, advertising lights are the easiest to be reduced while they impact on people’s lives the most. This essay will argue that advertising lights should be switched off after midnight to protect residents’ health and ecology.
Samsung and Apple are among the largest manufacturers and suppliers of smartphones in the current global market. Arguably, the need to produce an advanced cellphone that could do much more than just make or receive a phone call motivated the two companies to improve their products. The progress turned into two almost similar products that could offer the same service as the computer. Apple invented its technology back in 2007 and dominated the market for long, beating products like Nokia. Consumers loved the 1st generation iPhone’s cool screen touch features and multi-touch user interface. Although Apple has been successful throughout its progress in the Smartphone market,
For my citizen science project I will be helping to organize and collect data to measure the amount of light pollution that has been seen and growing throughout the years leading to “loss of the night”. No longer are you able to see stars in the sky like you were to hundreds of years ago but rather you are just able to see artificial lights that have, over time, intensified. For this project, I will be collecting visual data as well as computer/phone data. Through an app provided by the starters of the project, I will be taking photos of the sky, particularly at a certain stars to see how much of the night sky has been polluted with lamp designs. Through the data collection, I would be able to pay attention only to certain organisms, phenomena, and data because of the fact that these would be the main factors
There is a growing menace in today’s society known as light pollution. Light pollution is essentially excessive light from outside lighting fixtures that is misused and causes several negative effects. This increasing and perplexing issue is often magnified by industrialization and urban development which often neglects to consider the momentous problems light pollution causes. Despite serious efforts to minimize light pollution, “…light pollution rises about 6% every year” (Parks 30). One should know what light pollution entails, the adverse effects and costs of light pollution, ways it can be minimized, and how to appeal to the general public to help alleviate the problem.
“The world is nearly all parcelled out, and what there is left of it is being divided up, conquered and colonised. To think of these stars that you see overhead at night, these vast worlds which we cannot reach. I would annex the planets if I could; I often think of that. It makes me sad to see them so clear and yet so far.” (Shmoop Editorial Team)
Air pollution is caused by many things such as car fumes, burning of fossil fuels,
Light pollution affects the lives of people around the world. It comes in a variety of forms and can be a nuisance, wasteful, and harmful. It may be a street light shining in a window, a high energy bill, or the absence of stars in the sky. Light pollution is a growing problem as human populations continue to thrive, land is increasingly developed, and Earth’s precious resources are consumed. In order to reduce current levels of light pollution and to keep the problem from escalating out of control, action must take place.
You can take additional steps to reduce light pollution in your home and community by closing curtains and blinds to prevent light spill, educating neighbors about sky-friendly lighting practices, and proposing lighting ordinances to your local and state governments.
Light pollution is the “inappropriate or excessive usage of light causing glare, sky glow, and light trespass”. (IDA). Too much light washes out starlight in the night sky, which causes a lot of problems on earth (Haas). The more we educate ourselves on the effects of light pollution, the more effective we can be at minimizing the effects.
Earth Hour is an annual international event, organized by the World Wildlife Fund (WWF). This event actually asked us to think about what else we could be doing to make a difference to save our Earth. Countries that participate will switch off their lights for one hour to display a universal commitment to protect the one thing that unites us the entire planet. Unfortunately, most of us do not notice that this campaign will bring side effects, if we as a citizen participate in this campaign in a wrong way. Hence, the campaigns of Earth Hour has innumerable uses and like all campaigns, it has its drawbacks which encompass negative impact on human activities, enhancing energy reduction as well as releasing emission to the environment and perception of people about Earth Hour.
They are constantly researching, and modifying each other’s products in order to release their own with more innovative features. Both Apple and Samsung pour in billions of dollars for R&D (Research and Development) in order to stay ahead of each other. They both provide barriers against people who wish to enter the smartphone market through having built Brand Loyalty in its customers, and its constant R&D (Research & Development). Furthermore, Apple and Samsung are able to finance their own advertisements, and analyze their competitors and consumers through
Light pollution is a unique type indeed, also known as "sky glow" is a brightening of the sky at night caused by artificial lights being scattered by aerosol particles such as water droplets and dust in the air.
