The American Medical Association (AMA) has for years warned about the health effects of the glaringly bright white LED street lights. Skyglow. 50% of the light, due to poor shielding, is directed towards the sky, diminishing its view and hence, leading to energy wastage. Besides almost obliterating the stars from our night skies – more than a third of humanity is no longer able to see the Milky Way nowadays – light pollution has become a problem that goes as deep as the bottom of the sea. As a result, the world is slowly losing the beautiful dark sky view with the moon and the skies as well as other outer space objects. Per se, lighting that uses very powerful lights to light up the respective areas leads to a lot of energy wastage and serious environmental costs (carbon footprint).

She loves writing on topics related to space, environment, chemistry, biology, geology and geography. Alteration of the biological clock. Gegenschein is more pronounced in cities where the air is full of pollutants.2. With more lights, comes more needs for energy. Apart from the fact the individual businesses, homes, and public utilities pay for the lighting, the nation uses millions of money to generate electric power and loads of oil and non-renewable energy sources like coal are exploited to produce the ever needed power. (And Can They Choke on Raisins), Can Squirrels Eat Popcorn? Light pollution, the excessive or inappropriate use of outdoor artificial light, is affecting human health, wildlife behavior, and our ability to observe stars and other celestial objects. Working and living in artificially lighted environments have adverse effects on our organ systems leading to obesity, depression, sleep disorders, diabetes, cancers and more. According to environmentalists and researchers, light pollution causes visibility disruptions and nuisance especially from glares and the spillover effects which may lead to human health problems. In general, artificial lighting heavily impacts and threatens the balance of the ecosystem because numerous wildlife including plants and animals highly depend on the nocturnal and diurnal influences. Disturbing our body clocks has caused ill effects on the human body. But light pollution is not like water pollution, which is pollution of water. The devastating effects of light pollution on animals and ecosystems have been widely observed worldwide, especially near busy mega-cities, but this is the first study of its kind to look at what excessive artificial lighting is doing to creatures at the bottom of the sea, and to present actual measurements of its impact. 2. Effects of light pollution on health and wildlife. (And Which Foods to Avoid), Can Squirrels Eat Raisins? This is because artificial light disrupts our biological clock by altering the production of melatonin - the sleep hormone. Reduction of melatonin production in the body; hormone responsible for growth in the body. Light pollution is a side-effect of industrial civilization. © 2020 . The rhythm of life is orchestrated by the natural diurnal patterns of light and dark; so disruption to these patterns impacts the ecological dynamics. Linkages with health and wildlife have been a key focus in the geography literature. The port of Plymouth in southwest England, where research was conducted on the impact of artificial light on marine life. 1. The human eye is equipped to naturally adjust to the day and night patterns so as to see in the right manner. Luminous pollution has dire effects on our environment and resources of energy as well as wildlife ecology and astronomical research. The first issue that affects humans and the environment alike is energy consumption. The negative effects of light pollution impact many fields of study, including economics, ecology and, of course, astronomy. And that light that is scattered upwards is wasted and lost light. People are also at risk, however, from the direct impacts of living in areas where there are always lights on nearby. The researchers from the University of Plymouth spent four nights in 2018 studying the waters of Plymouth Sound and the Tamar estuary, looking for light infiltration – in the form of red, green and blue wavelengths – on the surface of the water, beneath the surface, and on the sea floor. Production for that energy commonly uses fossil fuels and non-renewable sources. Light pollution can disrupt animal health and behaviour; however, its effects on aquatic invertebrates are poorly understood. What is a Biome and What are Major Types of Biomes on Earth? When Light Pollution is bad enough, it has the ability to change the colour contrast of the night sky and eclipse natural starlight. Hormonal imbalances. Light pollution decreases the capacity of the zooplankton to consume algae from the water surface. Light Pollution is also defined as… “The Excessive, Invasive, or Misdirected Use of Artificial (manmade) Light. "Seventy-five per cent of the world's mega-cities are now located in coastal regions and coastal populations are projected to more than double by 2060," said Thomas Davies, the University of Plymouth marine conservation lecturer who led the study. Many wildlife animals such as mammals, birds, reptiles and insects are naturally photoperiodic. (And Which Foods Do They Actually Like), How Do Birds Mate? Effects of Noise & Light Pollution Noise pollution can cause stress, anxiety, headaches, irritability, hearing loss, and sleep loss resulting in decreased productivity. Numerous studies highlight immediate consequences on sleep. 3. Overpopulation. We found that unnatural light at n How Does Photosynthesis Take Place in Desert Plants? This is because when an open bulb releases light, most of it is directed upward, instead of focusing on a specific spot. You may love Christmas lights, but leaving them on all night is a form of pollution, as is leaving... 3. A study led by the University of Plymouth in the UK has found that the artificial light from coastal cities is affecting as many as three quarters of habitats on their neighboring sea floors. Beijing ICP prepared NO.16065310-3, Study shows light pollution reaches the sea floor, harming marine life. Baby sea turtles use moonlight reflecting on waves to reach the sea after hatching – unless artificial lights confuse them. In fact, light pollution can affect the areas surrounding our cities for tens or even hundreds of miles, reaching leaves no living thing ever untouched. Humans evolved to the rhythms of the natural light-dark cycle of day and night. While the studies found associations and not proof that light pollution causes diseases, some scientists theorize the suppression of melatonin could be directly responsible. Her passion for science education drove her to start EarthEclipse with the sole objective of finding and sharing fun and interesting science facts. The effects produced by light pollution affect not only human beings but also the flora and fauna exposed to it. That Earthly Sky Glow Light pollution is a global issue. It can confuse the migratory patterns of animals, alter competitive interactions of animals, change predator-prey relations, and cause physiological harm. Glares, light trespass, and clutter at night suggest some of the intricate aspects that have made the consequences of light pollution to be investigated. This type of light pollution cause what's called an 'artificial skyglow,' disrupting the natural biological cycles of the marine life living on sea floors which relies on the light of the moon to regulate itself for behaviors such as reproduction, sleep, food and protection from predators. Since peoples‘ sleep may be affected through light pollution, bad sleep can lead to all kinds of health conditions, including heart attack and … Irresponsible Use. When it seems that the city never sleeps – neither can we. And it is a direct result of both interior and exterior lighting in highly populated areas such as Edmonton. ", Copyright © 2020 CGTN. Poor Planning. Research suggests that artificial light at night can negatively affect human health, increasing risks for obesity, depression, sleep disorders, diabetes, breast cancer and more. "So unless we take action now, it is clear that biologically important light pollution on the sea floor is likely to be globally widespread, and increasing in intensity and extent, and putting marine habitats at risk. Sonia Madaan is a writer and founding editor of science education blog EarthEclipse. 4. Especially when they are feeding, sleeping, mating and also during migration cycles of all wildlife. Too much light can damage human eyes and even harm the hormone melatonin which is responsible for regulating diurnal and nocturnal visions. /VCG. This leads to an excessive algal bloom that may reduce the quality of water and also disturbs the life of flora of aquatic ecosystems. But there's another kind that poses a threat to humans and animals: light pollution. Waste of resources: It costs a lot of money to light up homes, public places, sports and commercial places. How do Rainbows Form? 2. Many characteristics of these animals’ behavior and physiology depend on the circadian rhythms, that is, the day and night influences. When she is not writing, she loves watching sci-fi movies on Netflix. Here are some of known side effects of light pollution. Light reflections can equally prevent natural UV rays from reaching the planet which is responsible for the continuity of plant life. Impact of Light Pollution on Health Light pollution also has clear health and environmental detriments, including harming abilities to sleep, increasing possible cancer, and harming animal behavior, including migration. Disrupted sleep patterns. Ways to reduce light pollution: Melatonin a hormone released according to the circadian rhythm of our bo… a street light designed to direct light downwards towards the street is more suited for its purpose. With respect to adverse health effects, many species, especi… The spread of artificial lighting means most of us no longer experience truly dark nights. Alteration of the life cycle of nocturnal animals. Light pollution negatively impacts on animal and plant physiology thereby modifying the competitive interactions of the animals, tampers with their migratory patterns, and distorts predator-prey relations. A light source that spills or scatters light in all directions is a major source of light pollution. The devastating effects of light pollution on animals and ecosystems have been widely observed worldwide, especially near busy mega-cities, but this is the first study of its kind to look at what excessive artificial lighting is doing to creatures at the bottom of the sea, and to present actual measurements of its impact. Can Squirrels Eat Bread? Hence, any amounts of artificial lights introduced in their respective environments can seriously alter their natural cycles and operations. Video of Learn about light pollution, including its effects on nature. On this regard, growth, development, reproduction, eating and locomotion all depend on the balance between day and night. It can create a disorienting experience for the wildlife if there is too much artificial light, especially during night time. In the case of humans, it can have the following negative health effects: 1. Light pollution also changes the natural illumination at night by brightening the skies and leads to the disruption of the ecosystem. Light pollution also affects the quality of life and safety of humans. The researchers are also investigating how individual species living on sea floors are affected by light pollution, while plans for global measurements involving an international team of scientists called Global Artificial Light Ocean Network (GLOW) have been postponed because of the COVID-19 pandemic. Another type of glow is known as ‘gegenschein’: this refers to the way that the sun’s rays illuminate gas and dust in the atmosphere causing a wide-ranging glow. (Albinism), Can Squirrels Eat Almonds? Learn about light pollution, including its effects on nature. Effects Of Light Pollution Light Pollution and its Effects. However, its effects can be felt beyond living beings, for example, in the impossibility of seeing the night sky, since light pollution prevents the vision of the stars and most other celestial phenomena during the night . According to environmentalists and researchers, light pollution causes visibility disruptions and nuisance especially from glares and the spillover effects which may lead to human health problems. Working at nights has become normal for a section of society that has become global and does not want to waste a moment of time. Artificial lighting pollution and the threat it poses to the animals, flora, and fauna including sea turtles | Britannica The placement of signage and street lights is planned by engineers, and if they do not take into... 2. Skyglow is the name for the reddish-yellow glow in the sky that persists throughout the night due to light pollution in the city below. Unlike other forms of pollution, light pollution has not been regarded as an important issue until lately. Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories, and, like any other form of pollution, disrupts ecosystems and has adverse health effects. The adverse effects of light pollution have also been observed in the aquatic ecosystem. The group behind the paper is hoping their research will trigger new policies looking into mitigating the negative impact of artificial lighting on the environment, and possibly reducing excessive lighting. Light pollutant Light pollution is the impact that anthropogenic light has on the visibility of the night sky. One of the negative effects of industrialization on human activity and the environment is the production of excessive light.
